The judging is finished and the scores are in, we now have the winners of our third Ubuntu App Showdown! Over the course of six weeks, and using the Ubuntu SDK, our community of app developers were able to put together a number of stunningly beautiful, useful, and often highly entertaining apps.

We had everything from games to productivity tools submitted to the competition, written in QML, C++ and HTML5. Some were ports of apps that already existed on other platforms, but the vast majority were original apps created specifically for the Ubuntu platform.

Best of all, these apps are all available to download and install from the Apps Scope on Ubuntu phones and tablets, so if you have a Nexus device or one with a community image of Ubuntu, you can try these and many more for yourself. Now, on to the winners!

QML Apps: Project Dashboard

Judges were astounded by the beautifully crafted Project Dashboard app, the winner of the QML category. Not only the idea and execution were brilliant, but also the fact that it’s a convergent QML application that runs on phones, tablet and desktop got it those coveted extra points from the jury.

With Project Dashboard you can keep track of different projects you’re managing or participating right from your device, in a very intuitive and easy way. For the geeks in us who contribute in several Open Source project, the excellent integration with Github makes it a pleasure to participate or manage the day to day of projects hosted in there.

Well done Michael Spencer!

HTML5 Apps: BE Mobile

bemobile

Say you’re in Belgium and want to get quickly from A to B with public transport? Then you’ll definitely want to use the winner of the HTML5 apps category: BE Mobile.

BE Mobile helps travellers find the best routes and times to travel within Belgium by selecting a journey and searching through a list of public transport services that can be enabled or disabled at will. In addition to that, a set of Twitter feeds for the services are provided, so that commuters and occasional travellers get informed in real time of disruptions and news for the lines they’re wanting to use.

What’s beautiful about it is the way in which using the SDK’s HTML5 components the app blends into the system exactly as a QML app. Convergence is also well-catered for with a responsive HTML design.

Congrats to Jelmer Prins!

Ported Apps: 2048

2048

Whoever has been online lately has surely heard about or played 2048. This addictive game created by 19-year-old Gabriele Cirully has quicky reached Internet popularity status and quite a following. And now Ubuntu has got its own ported version thanks to developer Victor Thompson, who takes home the prize for the best ported app in this Showdown!

A simple yet beautiful UI, combined with an engaging game experience will certainly grant hours of fun trying to reach that craved for 2048 tile!

Chinese Apps: QmlTextReader and Simple Dict

Chinese apps: QmlTextReader on the left, Simple Dict on the right

Chinese apps: QmlTextReader on the left, Simple Dict on the right

As a new category, we added “Chinese apps” for this third round of the App Showdown. Boren Zhang, who is also a Core Apps developer, contributed QmlTextReader, which had a simple design as its focus. It allows you to read novels and other texts and works very well for Chinese text. Font size and encoding can be changed and you can jump to where you left the text before. Perfect for long rides on the train or bus! Shenjing Zhu submitted a simple English/Chinese dictionary which is easy to use and very straight-forward. Both apps are very useful for readers and will come in handy quite often.

Go and get them all!

With retail Ubuntu phones getting closer and closer, the third Ubuntu App Showdown Ubuntu was a good opportunity to put the Ubuntu SDK, our documentation and our general approach to apps in Ubuntu to the test. In particular our HTML5 story has evolved to be on par with QML, so thanks a lot to all community developers and the Webapps team Engineers who have made this possible. During the course of these six weeks we’ve received great feedback from our developer community, worked out a large number of bugs in the SDK, and added or plan to add many new features to our platform.

It was also great to see how quickly all the apps were published in the app store and how little time had to be spent in reviews. The great thing is: if you have a device to run Ubuntu on or use the emulator, you can very easily install all the apps and take them for a spin. Six weeks is not a long time to write an app and get it to completion, but everybody worked hard, got their app in and we are very likely going to see more updates to the apps in the coming weeks.

Once again congratulations to Boren Zhang, Jelmer Prins, Michael Spencer, Shengjing Zhu, Victor Thompson and a big thank you to everybody who participated or helped those who participated, and everyone who has worked on building the Ubuntu SDK, Click tools and the App Store. And if you’re an app developer, or want to become an app developer, now is your time to get started with the Ubuntu SDK!

?? for all the submissions everyone!

Shortly before the submission deadline last night we had some small technical hiccups in the Ubuntu Software Store. This was fixed resolved very quickly (thanks a lot everyone who worked on this!), but we decided to give everyone another day to make up for it.

The new deadline is today, 10th April 2014, 23:59 UTC.

Please all verify that your app still works, everythings is tidy, you submitted it to the store and filled out the submission form correctly. Here’s how.

Submit your app

This is obviously the most important bit and needs to happen first. Don’t leave this to the last minute. Your app might have to go through a couple of reviews before it’s accepted in the store. So plan in some time for that. Once it’s accepted and published in the store, you can always, much more quickly, publish an update.

Submit your app.

Register your participation

Once your app is in the store, you need to register your participation in the App Showdown. To make sure your application is registered for the contest and judges review it, you’ll need to fill in the participation form. You can start filling it in already and until the submission deadline, it should only take you 2 minutes to complete.

Fill out the submission form.

Questions?

If you have questions or need help, reach out (also rather sooner than later) to our great community of Ubuntu App Developers.

We’ve recently rolled out some changes to the submission process for Click Applications that should make it easier for you to submit new applications, and allow them to be approved more quickly.

Previously when submitting an application you would have to enter all the information about that application on the website, even when some of that information was already included in the package itself. This was firstly an irritation, but sometimes developers would make a mistake when re-entering this information, meaning that the app was rejected from review and they would have to go back and correct the mistake.

With the new changes, when you submit an application you will wait a few seconds while the package is examined by the system, and you will then be redirected to the same process as before. However this time some of the fields will be pre-filled with information from the package. You won’t have to type in the application name, as it will already be there. This will speed up the process, and should reduce the number of mistakes that happen at that stage.

We’ve also been working on a command-line interface for submitting applications. It’s not polished yet, but if you are intrepid you can try out click-toolbelt.

ubuntu-phone-three-1

There is lots of excitement around Ubuntu on phones and tablets. Especially with two handsets coming out later this year and features and more beauty landing every single week, it’s a lot of fun to watch the whole story unfold.

What many haven’t realised yet, is how easy it is to write apps for Ubuntu and that new apps are not only going to run on phones and tablets, but also on the desktop as well. To remedy that we put some work into making it easy to go out to events and give talks about Ubuntu and its app ecosystem.

What we have available now is:

  • improved presentation materials,
  • we made it easier for newcomers to step in, learn and present,
  • we reach out to app developer communities and our LoCo teams at the same time.

We have two great sets of events coming up soon: the Ubuntu Global Jam coming up in just 2 weeks and soon followed by the 14.04 release and its release parties.

Interested? So how do you prepare? Easy:

  • As somebody who can organise events, but might need to find a speaker: Ask in #ubuntu-app-devel on Freenode or on the ubuntu-app-devel@ mailing list, to see if anyone is in your area to give a talk. Ask on your LoCo’s or LUG’s mailing list as well. Even if somebody who’s into programming hasn’t developed using Ubuntu’s SDK yet, they should be able to familiarise themselves with the technologies quite easily.
  • As somebody who has written code before and didn’t find the Ubuntu app development materials too challenging, but might need to find some help with organising the event: Ask on the loco-contacts@ mailing list. There are LoCos all around the world and most of them will be happy to see somebody give a talk at an event.

Whichever camp you’re in:

  • Check out our docs. They explain what’s required to make the event a success.
  • Join our Q&A session. It’ll be at 27 March 2014, 18:00 UTC on Ubuntu on Air. (The video of session today is up here.)
  • Talk to us. Just comment on the blog post and we can surely help you out somehow.

Let’s make this happen together. Writing apps for Ubuntu and publishing them has never been easier, and they’ll make Ubuntu on phones/tablets much more interesting, and will run on the desktop as well.

Announcing the latest Ubuntu App Showdown contest!

image-app-showdown

????????

Today we are announcing our third Ubuntu App Showdown! Contestants will have six weeks to build and publish their apps using the new Ubuntu SDK and Ubuntu platform. Both original apps and ported apps, QML and HTML 5, will qualify for this competition.

Categories and prizes

This App Showdown is going to be very special, because we will have four dedicated categories in which you can participate and win a prize.

  1. QML: original apps written in QML or with a combination of QML and JavaScript/C++
  2. HTML5: original apps written using web technologies, be it pure HTML (and CSS/JavaScript) or with platform access using Apache Cordova
  3. Ported: apps ported from another platform, regardless of the technology used
  4. Chinese apps: apps in this category will have to be original and specific to China and the Chinese culture. They will be judged by two native experts in our jury.

The set of prizes will consist of a Nexus 7 (2013) per category for QML, HTML5 and ported apps.
Nexus7-2013


The top two Chinese apps will receive a Meizu device each.
Meizu-MX3

Review criteria

Apps in the HTML5/QML/Ported categories will be reviewed by a jury composed by an international team of five judges:

  • Jono Bacon, Ubuntu Community Manager
  • Adnane Belmadiaf, Ubuntu HTML5 expert
  • Lucas Romero di Benedetto, Ubuntu Community Design Team
  • Nekhelesh Ramananthan, Ubuntu Core App Developer
  • Joey-Elijah Sneddon, OMG!Ubuntu editor

The judges for the Chinese apps are:

  1. Shuduo Sang?Software Engineer in Canonical PES
  2. Joey Chan, Ubuntu Core App Developer
  3. Jack Yu, Ubuntu Kylin Lead/Ubuntu Member

The jury will judge applications according to the following criteria:

  • General Interest – apps that are of more interest to general phone users will be scored higher. We recommend identifying what most phone users want to see, and identifying gaps that your app could fill.
  • Convergence – apps that have a convergent layout that expands to dedicated tablet mode or optionally run well on the desktop will also be scored higher.
  • Features – a wide range of useful and interesting features.
  • Quality – a high quality, stable, and bug-free application experience.
  • Design – your app should harness the Ubuntu Design Guidelines so it looks, feels, and operates like an Ubuntu app.
  • Awareness / Promotion – we will award extra points to those of you who blog, tweet, facebook, Google+, reddit, and otherwise share updates and information about your app as it progresses.
  • Chinese culture – apps optionally submitted in the China category will be reviewed with the same criteria above, plus their relevance to Chinese users of the app. This can be by providing access to Chinese services, being related to Chinese culture or being generally useful to somebody in the People’s Republic of China.

We are starting a blog series where we interview our Ubuntu App Heroes. We want to learn more about how developers found the experience writing apps for Ubuntu, what their plans are, what they do and who they are.

Kicking off the series, we had a quick chat with the two guys working on the beautiful Weather app, Martin Borho and Raúl Yeguas.

Martin Borho Raúl Yeguas

Can you introduce yourselves?

Raúl: My name is Raúl Yeguas, I’m a frontend developer and I live in Seville in Spain. I studied IT at the University of Jaén where I organised some free software events. I’m a great Qt fan and a proud KDE user.

Martin: My name is Martin Borho, I’m 37 years old and I live in Hamburg, Germany. I work as a freelance programmer, mainly coding Python.

When and how did you get involved in the Ubuntu Core Apps project?

Martin: As Ubuntu Touch was announced, there was a little form at the webpage, asking for interested persons willing to contribute. As I was searching for a project I could join at that time, I filled it out….

Rául: I noticed Canonical’s call for developers on QtPlanet. When I subscribed to Canonical’s first announce I thought that it was for helping developers to write their own apps for their platform; but when I received the emails from them asking me what core app I wanted to work on I was so surprised and excited. I’m part of the Core Apps Developers from the beginning.

Have you developed apps before?

Martin: Yes, I’ve started doing a mobile app, named “Ask Ziggy”, on my Nokia N900 in 2010. In 2011 I’ve built an app for Google News called “NewsG” for WebOS. Which I later ported to Qt/QML, to get it on my Nokia N9/N950.

Raúl: Yes, mainly C++/Qt apps and HTML/JS webapps.

What was your experience learning everything involved to work on the Weather app?

Martin: Hmm, initially I had no idea what to expect. After all I have learned quite a few things (and still do). Contributing to a large scale project with people from all over the world is one, how various parts have to fit together is another one. It is fascinating to see how Ubuntu Touch has evolved over the last months.

Raúl: I have to say that this team is awesome. I learned too much from them, mainly about working in team with distant people and about designing new ways to interact with an app.

Weather App Designs

Weather App Designs

Is there anything you are proud of or feel is solved very well in the Weather app?

Raúl: Yes, the gestures to change between daily forecast and hourly forecast. I think is too easy to use and intuitive.

Martin: Hard to say, perhaps: It’s quite easy to add more weather data providers to the app, without having to deal much with the UI part. And having a distinction between fast and slow scrolling, to flip between days, respective hours, is quite nice.

What can new app developers learn from your app?

Martin: Can’t say… as I’m doing Qt/QML only in my spare time I don’t think it’s very sophisticated in that regard.

Raúl: I think that our app has well organised and differentiated graphics components so I think that it could be a good example for learning how to create complex QML components by creating simple parts. It also has a very good API to call weather info providers.

What can users of the app expect in the coming months?

Martin: The integration of Weather Channel as a second weather data provider is nearly finished and will be ready to get merged into trunk very soon. Apart from that, Raúl is currently working on new animated icons, which will be very nice when ready.

Raúl: Yes, expect some new animations for eye-candy and a new weather information provider.

Do you have any other hobbies apart from working on Ubuntu?

Martin: I like biking. And as the stadium of my favourite club is only a 5 minute walk away, I like watching football too … ;-)

Raúl: Yes, like non-IT people have. ;) I like watching movies, playing videogames and traveling. When I have enough time I produce electronic music. But I have to confess that sometimes I contribute on other open source projects \o/

Christmas has come early in Ubuntu this time around, with a finely wrapped present: dual-booting with Android.

We are thrilled to announce a preview of a new feature for developers: Ubuntu on mobile devices can now run alongside Android on a single handset.

For developers only

Dual boot is not a feature suitable for regular users. It is recommended to be installed only by developers who are comfortable with flashing devices and with their partition layout. Dual boot rewrites the Android recovery partition and those installing it should be intimately familiar with re-flashing it in case something goes wrong.

Multiple Android flavours are supported (AOSP or stock, CyanogenMod) and installation of Ubuntu can be done for all versions available in the phablet-flash channels.

Easy OS switch via apps

With dual boot, switching between OSs had never been easier. No more key combinations or command line interfaces to jump into the next OS: on each side, an app with a simple user interface will enable you to boot back and forth at the tap of a button.

Ubuntu dual boot on Android

The Android app manages the initial installation of Ubuntu, upgrades and rebooting into Ubuntu.

Ubuntu dual boot

On Ubuntu, the dual boot app provides an easy way to reboot into Android.

Installing dual boot

Installing and running dual boot can be done in a few easy steps. In a nutshell, it requires performing a one-off installation of the dual boot app in Android, which will enable you to both install the version of Ubuntu of your choice, and to reboot into Ubuntu.

Convergent File ManagerConvergence is going to be a major theme for Ubuntu 14.04, not just at the OS and Unity 8 levels, but also for the apps that run on it. The Core Apps, those apps that were developed by the community and included by default in the last release, are no exception to this. We want to make sure they all converge neatly and usefully on both a tablet and on the desktop. So once again we are asking for community design input, this time to take the existing application interfaces and extend them to new form factors.

How to submit your designs

We have detailed the kind of features we want to see for each of the Core Apps on a Convergence wiki page. If you have a convergence design idea you would like to submit, send it as a file attachment or link to it online in an email to design@canonical.com along with any additional notes, descriptions, or user stories.  The design team will be reviewing the submitted designs live on their bi-weekly Design Clinics (Dec 4th and Dec 18th) at 1400 UTC.  But before you submit your ideas, keep reading to see what they should include.

Extend what’s there

We don’t want to add too many features this cycle, there’s going to be enough work to do just building the convergence into the app.  Use the existing features and designs as your starting point, and re-imagine those same features and designs on a tablet or desktop.  Design new features or modify existing ones when it makes the experience better on a different form factor, but remember that we want the user to experience it as the same application across the board, so try and keep the differences to a minimum.

Form follows function

There’s more to a good design than just a good looking UI, especially when designing convergence.  Make sure that you take the user’s activity into account, plan out how they will access the different features of the app, make sure it’s both intuitive and simple.  The more detail you put into this the more likely you are to discover possible problems with your designs, or come up with better solutions that you had originally intended.

Think outside the screen

There is more to convergence that just a different screen size, and your designs should take that into consideration.  While it’s important to make good use of the added space in the UI, think about how the user is going to interact with it.  You hold a tablet differently than you do a phone, so make sure your designs work well there.

On the desktop you have even more to think about, when the user has a keyboard and mouse, but likely not a touch screen, you want to make sure the interface isn’t cumbersome.  Think about how scrolling will be different too, while it’s easy to swipe both vertically and horizontally on a phone or tablet, you usually only have a vertical scroll wheel on a desktop mouse.  But, you also have more precise control over a mouse pointer than you do with a finger-tip, so your interface should take advantage of that too.

Resources available to you

Now that you know what’s needed, here are some resources to help you.  Once again we have our community Balsamiq account available to anybody who wants to use it to create mockups (email me if you need an account).  I have created a new project for Core Apps Convergence that you can use to add your designs.  You can then submit links to your designs to the Design Team’s email above.  The Design Team has also provided a detailed Design Guide for Ubuntu SDK apps, including a section on Responsive Layouts that give some suggested patterns for different form factors.  You can also choose to use any tools you are comfortable with, as long as they Design Team and community developers can view it.

At the same time that Ubuntu 13.10 was released, we also went live with a new API documentation website here on the Ubuntu Developer Portal. This website will slowly replace our previous static docs, which came in a variety of formats, with a single structured place for all of our developer APIs. This new site, backed by Python and Django, will let us make our API documentation more easily discoverable, more comprehensive, and more interactive over time.

Screenshot from 2013-10-17 09:54:41

We launched the site with only the documentation for the Ubuntu UI Toolkit, as well as upstream QtQuick components. But in the past week we’ve added on to that API documentation for the new Content Hub, which allows confined apps to request access to files (pictures, music, etc) stored outside of their sandbox, as well as a full new section of HTML5 API docs covering the visual components developed to match the look and feel of their Qt/QML counterparts.

Today a major milestone in the history of Ubuntu and the mobile industry has been reached: we’re extremely proud to celebrate the release of Ubuntu 13.10, the free, open source operating system for smartphones, desktop and server.

A release for mobile developers

phone-apps-grid-extended-cut

As of today, Ubuntu is available on the desktop, on servers and on smartphones. Ubuntu’s first ever mobile edition provides an operating system with all applications phone users need for their day-to-day, in addition to a thriving app ecosystem and a platform application authors can target.

This is the first leap on the road to convergence and having an OS to rule all devices and form factors.

Native or web: your choice

The Ubuntu SDK enables developers to easily create applications that make use of the full capabilities of the platform and integrate naturally with the OS. It contains Qt Creator, a full-fledged IDE with code-editing, debugging and device deployment features; the UI toolkit, with a set of widgets and components to be used as building blocks for Ubuntu apps; and detailed developer documentation, including API docs and tutorials.

As part of the app developer story both native and web are first-class citizens. For the native approach, QML combined with JavaScript is the easiest way to write Ubuntu apps, while C++ is also fully supported. The SDK is powered by the widely used Qt framework.

For those writing or porting HTML5 applications, the SDK features various levels of support to cover all web developer needs:

  • HTML5 apps – use web technologies to write apps
  • HTML5 Cordova apps – use web technologies to access native device functions such as camera and sensors
  • Webapps – integrate a website with Ubuntu and launch it as an app

The SDK also uses the full capabilities of OpenGL ES graphics acceleration, providing high-quality 3D rendering for the most demanding games.

Community-driven core apps

app_shocase-700px

As a testament to the stunning result that can be achieved combining a vibrant community of developers, a team of designers and the Ubuntu SDK, we’re also thrilled to announce the availability of the 12 core apps for the phone. Core applications have been designed from the ground up to provide the basic functionality a user needs for their every day, and more. They include:

  • Daily apps: Music, Clock, Weather, Calendar, RSS reader, Calculator
  • Games: Sudoku, Dropping Letters
  • Developer tools: Terminal, File Manager

These apps complement the offer of pre-installed software on the phone, including Dialer, Messaging, Browser, Camera, Gallery, Notes, Contacts and a set of webapps such as Twitter and Facebook.

Core apps have been entirely created by teams of community contributors and Canonical designers. Volunteer contributions have ranged from development, design, QA to bug reporting and support.

We’d like to thank all developers and any contributors who have in any way made the core apps happen. The work you’ve done in the last few months and the commitment you’ve shown to the project is just unbelievable, you rock!

App Showdown Winners

The judging is finished and the scores are in, we now have the winners of this year’s Ubuntu App Showdown!  Over the course of six weeks, and using a beta release of the new Ubuntu SDK, our community of app developers were able to put together a number of stunningly beautiful, useful, and often highly entertaining apps.

We had everything from games to productivity tools submitted to the competition, written in QML, C++ and HTML5. Some were ports of apps that already existed on other platforms, but the vast majority were original apps created specifically for the Ubuntu platform. Best of all, these apps are all available to download and install from the new Click store on Ubuntu phones and tablets, so if you have a Nexus device or one with a community image of Ubuntu, you can try these and many more for yourself.  Now, on to the winners!

Original Apps #1: Karma Machine

karma_machine_subredditkarma_machine_contentkarma_machine_commentsKarma Machine is wonderful app for browsing Reddit, and what geek wouldn’t want a good Reddit app?  Developed by Brian Robles, Karma Machine has nearly everything you could want in a Reddit app, and takes advantage of touch gestures to make it easy to upvote and downvote both articles and comments.  It even supports user accounts so you can see your favorite subreddits easily.  On top of it’s functionality, Karma Machine is also visually appealing, with a good mix of animations, overlays and overall use of colors and layouts.  It is simply one of the best Reddit clients on any platform (having written my own Reddit client, that’s saying something!), and having it as an original Ubuntu app makes it a valuable addition to our ecosystem.  With all that, it’s little wonder that Karma Machine was tied for the top spot on the judges list!

Original Apps #1: Saucy Bacon

saucy_bacon_searchsaucy_bacon_toolbarsaucy_bacon_editSomething for the foodies among us, Saucy Bacon is a great way to find and manage recipes for your favorite dish. Backed by food2fork.com, this app lets you search for recipes from all over the web.  You can save them for future reference, and mark your favorites for easy access over and over again.  And since any serious cook is going to modify a recipe to their own tastes, Saucy Bacon even lets you edit recipes downloaded from somewhere else.  You can of course add your own unique recipe to the database as well.  It even lets you add photos to the recipe card directly from the camera, showing off some nice integration with the Ubuntu SDK’s sensor APIs and hardware capabilities.  All of this mouth-watering goodness secured developer Giulio Collura’s Saucy Bacon app a tie for the #1 stop for original Ubuntu apps in our contest.

Ported Apps #1: Snake

The game Snake has taken many forms on many platforms throughout the years.  It’s combination of simple rules and every-increasing difficulty has made it a popular way to kill time for decades.  Developer Brad Wells has taken this classic game from Nokia’s discontinued Meego/Harmattan mobile OS, which used a slightly older version of Qt for app development, and updated it to work on Ubuntu using the Ubuntu SDK components.  Meego had a large number of high quality apps written for it back in it’s day, and this game proves that Ubuntu for phones and tablets can give those apps a new lease on life.

Go and get them all!

The 2013 Ubuntu App Showdown was an opportunity for us to put the new Ubuntu SDK beta through some real-world testing, and kick off a new app ecosystem for Ubuntu.  During the course of these six weeks we’ve received great feedback from our developer community, worked out a large number of bugs in the SDK, and added or plan to add many new features to our platform.

In addition to being some of the first users of the Ubuntu SDK, the app developers were also among the first to use the new Click packaging format and tools as well as the new app upload process that we’ve been working on to reduce review times and ease the process of publishing apps.  The fact that all of the submitted apps have already been published in the new app store is a huge testament to the success of that work, and to the engineers involved in designing and delivering it.

Once again congratulations to Brian Robles, Giulio Collura and Brad Wells, and a big thank you to everybody who participated or helped those who participated, and all of the engineers who have worked on building the Ubuntu SDK, Click tools and app store.  And if you have a supported device, you should try out the latest Ubuntu images, and try these and the many other apps already available for it.  And if you’re an app developer, or want to become an app developer, now is your time to get started with the Ubuntu SDK!

The winners of this contest will each receive an LG Nexus 4 phone running Ubuntu Touch with their application pre-installed. Furthermore, each of the winners will have an opportunity to have their app included in the default Ubuntu install images for phones and tablets.

All valid entries will also become available for install on Ubuntu Touch devices from the Apps lens in the Dash, using the new Click packages and MyApps submission process.

Judges

The jury will be composed by a team of five judges:

  • Jono Bacon, Ubuntu Community Manager
  • Joey-Elijah Sneddon, writer and editor-in-chief of OMG!Ubuntu
  • Lisette Slegers, User Experience Designer at Canonical
  • Nekhelesh Ramananthan, Ubuntu Touch Core App developer
  • Bill Filler, Engineering Manager for the Phone & Tablet App Team

Review criteria

The jury will judge applications according to the following criteria:

  • General Interest – apps that are of more interest to general phone users will be scored higher. We recommend identifying what most phone users want to see, and identifying gaps that your app could fill.
  • Features – a wide range of useful and interesting features.
  • Quality – a high quality, stable, and bug-free application experience.
  • Design – your app should harness the Ubuntu Design Guidelines so it looks, feels, and operates like an Ubuntu app.
  • Awareness / Promotion – we will award extra points to those of you who blog, tweet, facebook, Google+, and otherwise share updates and information about your app as it progress.

If you are not a programmer and want to share some ideas for cool apps, be sure to add and vote apps on our reddit page.

Today we are pleased to announce the beta release of the Ubuntu SDK! The SDK is the toolkit that will power Ubuntu’s convergence revolution, giving you one platform and one API for all Ubuntu form factors. This lets you write your app one time, in one way, and it will work everywhere.  You can read the full Ubuntu SDK Beta announcement here.

For the developers who are already writing apps using the Ubuntu SDK most of the beta’s features will already be known, as they have been landing in the daily releases as they become finished. Here’s a list of the features that have been added since the alpha:

  • Cordova Ubuntu HTML5 app template – leverage the Apache Cordova APIs to write Ubuntu apps with web technologies: HTML, JavaScript and CSS. Write your first HTML5 with the Cordova Ubuntu tutorial.
  • Ubuntu SDK HTML5 theme – a companion to all HTML5 apps: stylesheets and JavaScript code to provide the same look and feel as native apps
  • Responsive layout – applications can now adopt a more natural layout depending on form factor (phone, tablet, desktop) and orientation
  • Scope template – Scopes enable operators to prioritise their content, to achieve differentiation without fragmentation. Now easier to create with a code template
  • Click packaging preview – initial implementation of the Click technology to distribute applications. Package your apps with Click at the press of a button
  • Theme engine improvements – a reworked theme engine to make it easier and more flexible to customise the look and feel of your app
  • Unified Actions API – define actions to be used across different Ubuntu technologies: the HUD, App Indicators, the Launcher, the Messaging Menu
  • U1DB integration – the SDK now provides a database API to easily synchronise documents between devices, using the Ubuntu One cloud

Some of the biggest news here is the Cordova support and HTML5 theme, which brings together our goal of making first class HTML5 app that look and feel like native apps.  Cordova support means that apps written using the PhoneGap framework can be easily ported to Ubuntu Touch, and the HTML5 themes, written largely by community developer Adnane Belmadiaf, will allow those apps to match the native SDK components in both the way they look as well as the way the user interacts with them.

The Responsive Layouts, which landed in the daily SDK packages weeks go, gives developers the ability to adjust their application’s GUI dynamically at runtime, depending on the amount of screen space available or any number of other variables.  This is one key to making convergent apps that can adapt to be useful on both small touch screens and large monitors with a keyboard and mouse.

We’ve also put out the first set of Click packaging tools, which will provide an easier way for developers to package and distribute their applications both on their own and through the Ubuntu Software Center.  There is still a lot more work to do before all of the Click infrastructure is in place, but for now developers can start trying getting a feel for it.

All of that and more is now available, so grab the latest SDK packages, read the QML and HTML5 app development tutorials, and get a head start building your convergent Ubuntu application today!

Help shaping up Ubuntu Touch by joining the core apps development teams

Community-driven apps that will power the next million phones

The Ubuntu Core Apps project started as an initiative born out of the initial Ubuntu Touch announcement, with a call to our community to participate in building the core set of applications which will be considered for shipping on Ubuntu phones.

With this, we started an exciting project that provides a unique opportunity for community members to create Free Software that could run on millions of handsets.

If you’re running Ubuntu Touch on a device, you can already see the results of the work our amazing volunteer developers have been doing: Calculator, Clock, Calendar, Weather, Terminal, File Manager… these apps and more are part of this project. Together with the Canonical designers and other community designers, we’ve also got a solid UX and design story for our applications.

In essence, each core app development team organizes their work and time in the way that works best for them, where the Canonical Community, Design and Engineering teams participate in several different areas:

  • Development infrastructure
  • Engineering management
  • Community mentorship and support
  • Design guidance

With this post I’d like to share how any developer can contribute to core apps and join the core dev teams. It’s not only an opportunity to shape up Ubuntu Touch, but also to work in a truly open development environment, with the best Open Source developers and designers out there!

Participating in the core apps project

Getting started to contributing to core apps is just a few minutes away. Here are some really easy steps for developers to get all set up.

Step 1: install all core apps

While some of the apps are already installed on the Ubuntu Touch image, you’ll be doing your development on the desktop. As part of the convergency story, core apps run equally well on phones, tablets or desktops, so the first step will be to get familiar with them and do some dogfooding.

  1. Open a terminal by pressing Ctrl+t and type the commands below, followed by Enter.
  2. Install the Ubuntu SDK: sudo add-apt-repository ppa:canonical-qt5-edgers/qt5-proper && sudo add-apt-repository ppa:ubuntu-sdk-team/ppa && sudo apt-get update && sudo apt-get install ubuntu-sdk
  3. Install the core apps: sudo add-apt-repository ppa:ubuntu-touch-coreapps-drivers/daily && sudo apt-get update && sudo apt-get install touch-coreapps

If you get stuck here, check out the SDK’s getting started page or ask on Ask Ubuntu

At this point you’ll be able to launch any of the core apps from the Dash.

  • Try opening the Dash clicking on the Ubuntu button in the Launcher, and type the first letters of each one of the apps to launch them. You should now be able to install:
    1. Calculator
    2. Calendar
    3. Clock
    4. Document viewer
    5. Dropping Letters
    6. Email
    7. File Manager
    8. Music
    9. RSS Reader
    10. Stock Ticker
    11. Sudoku
    12. Terminal
    13. Weather

Step 2: pick an app and find something to work on

Once you’ve road-tested all of the apps, you’ll have a good overview of their functionality, and where you think you can help. At this point, the best thing to do is to pick an app you’re interested in contributing to and find more about it:

  1. Go to the core apps overview page
  2. Click on the app you’re interested in. This will show you:
    • The public project where the app is being developed and where the code is hosted
    • The development team who is writing the app
    • The IRC channel where to discuss about the app’s development in real time
    • The blueprint we use to track the items to work on to implement the functional requirements
    • The burn-down chart we use to provide an overview of the status of the work

The best way to get started is to look at the existing code for the app. Here’s how:

  1. If you haven’t already, open a terminal with Ctrl+t and type this command to install the Bazaar revision control system: sudo apt-get install bzr
  2. Get a local copy of the code. Run this command, replacing ubuntu-clock-app by the app you’ve chosen. You’ll find the exact name to replace on the project section of the app’s detail page you opened earlier on: bzr branch lp:ubuntu-clock-app
  3. Start Qt Creator, the Ubuntu’s SDK IDE by clicking the Ubuntu button on the Launcher and typing “ubuntu sdk”
  4. In Qt Creator, press Ctrl+o to navigate to the location where you’ve just downloaded the code to and choose the .qmlproject file to open the app’s project in the IDE
  5. You can now study the code and launch it with either the Ctrl+r key combination or by pressing the big green “Run” button in Qt Creator

Before you start doing any changes in the code, you might want to get in touch with us to ensure no one is already working on what you’re intending to start on. Two good places to look at are:

Step 3: send a merge proposal with your contribution

In our distributed collaborative environment, where thousands of volunteers participate in Ubuntu from all over the world, we use a distributed version control system, Bazaar to manage the code’s revisions.  The code for all core apps is hosted in public projects in Launchpad, the online tool where we do all development.

You can easily do your changes to the code locally, publish them in a public branch and then send a request for the core app development teams to review and merge your code.

Check out the core apps development guide for the full details ›

Many ways to contribute

Although development is where you can make most of an impact at this point, there are many other ways to participate. You can:

Get in touch

We’d like to hear from you!. If you’ve got QML programming skills and would be interested in joining one of the core apps teams, get in touch with Michael Hall, David Planella or Alan Pope and we’ll gladly guide you in the first steps to becoming a core app dev.

You can also join any of the public IRC core app development meetings.

Looking forward to welcoming you in the core apps project!
