Random Android Gradle Tip: Different Icon per BuildType

Say you want to tell if the version of your installed app is a debug or release version just by looking at the icon on your device. Quick way to do this is to leverage Gradle’s Build type concept.
Build types allow you to create different versions of the same app from the same project. All projects have by default, a debug and release build type. If you want to have a different debug icon from your release icon.

All you have to do is create your launcher icon (debug version) and instead of placing the drawables in the main source set you would install them in the debug source-set. When your project is built in debug mode it would use the matching assets in the debug folder instead of the assets in main source folder. When you build the release version it will use the assets in the release folder if it exists or use the default ones in the main source set. This also holds for build variants.

Random Android Gradle Tip: App dependencies

If you need to see the dependency tree for your project you can run:
./gradlew :app:dependencies
and
./gradlew :app:androidDependencies
if you need to solve a conflict you could either exclude the conflicting module or use a resolution strategy to force a particular version of the library to be used .
