Cyril, thanks for sharing, very useful! One question, beyond the subject though. I thought we need to compile the project with the minimum API defined for it, but I can see 'compileSdkVersion 18' in your build.gradle while 'minSdkVersion 14'.

Is it possible to read storePassword etc from external file? I don't want to put it in gradle file.

'git diff' can be replaced by 'git diff --shortstat'. I deleted a lot of files in a repo, and it made Gradle go out of memory. Took time to figure out what was going on ;)

BuildConfig.FLAVOR may return nothing when it is called from any extended class of ContentProvider. In my case, I use a singleton class to create a static content authority string from something similar to buildAuthority() and set android:authorities="${applicationId}.citybikes.provider.CityBikesProvider" in AndroidManifest.xml
