In Feburary 2012, Blackberry updated the OS for their 7″ Playbook tablet to v2.0. This introduced compatailbity with Android-based applications whereby developers can simply repackage, code sign, and submit their Android apps into BlackBerry App World. It also means you can take any Android app (that hasn’t gone through this process) and sideload the app yourself.
Since I develop mobile apps for iOS and Android using the Titanium platform, I was interested in how much effort it would be to get my existing apps working on the Playbook. There are plenty of posts on how to take an APK and sign it correctly for App World, but what took me a while to figure out, was which version on Titanium was compatible with the Playbook.
After some experimentation, I’ve found that if you package your app against Titanium SDK 1.7.5, it’ll work nicely on the Playbook. Version 1.8.x won’t work (hmm, maybe it’s V8 vs Rhino.. V8 definitely doesn’t work…). Certain pieces of code may also cause the app to crash (whereas it won’t crash on a proper Android device). The one thing I hit, was passing url:null, into Titanium.UI.createWindow will crash the app, whereas that’s absoutely fine on iOS and Android.
The other small advantage of using the 1.7.5 SDK is that the resulting APK is a lot smaller, although since the current Playbook only has Wifi this is less of an issue than it is on a mobile phone.
Now we have the APK, you just have to go through the app packaging/signing process as detailed elsewhere on the web, or in Blackberry’s official documentation. This new GUI-based tool looks like a good place to start if you don’t like working from the command line.
