For enabling Proguard configurations for your application you need to enable it in your module-level gradle file. You need to set the value of minifyEnabled
to true
.
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
The above code will apply your Proguard configurations contained in the default Android SDK combined with the "proguard-rules.pro" file on your module to your released apk.
