ANDROID STUFF
All you need you get over here http://developer.android.com/index.html The SDK -> http://developer.android.com/sdk/index.html
SETUP
Import with Android-Studio should go seamlessly.
To run the app on the emulator or a phone you have to … … compile to the target SDK (Not min SDK) otherwise you'll get compile errors. … add the sudoq-model to your sudoq-app project's buildpath in case eclipse got that wrong. … create an assets folder called assets within the sudoq-app project and put the Sudokus folder which contains pre-generated Sudokus in it.
WORKING THE CODE
Some advise:
Keep any android specific code away from the model. In case you got stuck: http://xkcd.com/ or http://stackoverflow.com/questions/tagged/android
That should be all. In case of emergencies Don't Panic, and call one of the devs.
And don't forget your towel!
