问题
My Activities , Fragments ,Services and BroadcastReceivers I want to implement a ProGuard taken to the safety of the classroom. Error I get when Proguard. What should I write into the file? -> proguard-android.txt ve proguard-rules.pro
I'd written into the grade.
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}

proguard-rules for butterknife:8.8.1

-keep public class * implements butterknife.Unbinder { public <init>(**, android.view.View); }
# Prevent obfuscation of types which use ButterKnife annotations since the simple name
