Android applications are built using the open source Gradle build system. Gradle is a state-of-the-art API that easily supports customizations and is widely used in the Java world. The Android plug-in for Gradle adds a wide range of features specific to Android apps, including build types, flavors, signing configurations, library projects, and more.
