Use Proguard For Stripping Unused Support Lib Classes

I'm adding the Android Support library to my project and I've noticed the resulting APK file inflates in size quite a bit. What I'm trying to do is use Proguard to remove classes

Solution 1:

The Android SDK only applies ProGuard in release builds, not in debug builds.

Furthermore, the Android SDK (r20 or higher) typically looks for proguard-project.txt instead of proguard.txt in your project. This file can generally be empty, because the build process also reads the global file proguard-android.txt. You may want to update your project with

android update project -p MyProjectDirectory

Finally, the Android SDK (r20 or higher) disables ProGuard's optimization step by default (which can improve on its shrinking step). You can enable it by pointing to proguard-android-optimize.txt instead of proguard-android.txt in your project.properties.
