Shrink Your Code and Resources

Resource shrinking is available with the Android plugin for Gradle, which removes unused resources from your packaged app, including unused resources in code libraries. It works in conjunction with code shrinking such that once unused code has been removed, any resources no longer referenced can be safely removed as well.

For example, the following snippet from a build.gradle file enables code shrinking for the release build:

android {
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile(‘proguard-android.txt’),
‘proguard-rules.pro’
}
}

}
