2// This Gradle build file illustrates how to process Android
3// applications.
4// Usage:
5//     gradle -b android.gradle proguard
6//
7// If you're using the Android SDK, the Ant release build and Eclipse export
8// already take care of the proper settings. You only need to enable ProGuard
9// by commenting in the corresponding line in project.properties. You can still
10// add project-specific configuration in proguard-project.txt.
11//
12// This configuration file is for custom, stand-alone builds.
13
14// Tell Gradle where to find the ProGuard task.
