Android proguard file to remove log messages. This is tested and actually works with Android Studio 0.8.8 You need to add some lines to the build.gradle file (see notes below) Includes library-specific rules for Guava, Crashlytics, OkHttp, Retrofit, Otto

# To use this file, your project's build.gradle 'buildTypes' section should look like this:
#
#  buildTypes {
#           release {
#               minifyEnabled true
#               proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), '../proguard-rules.txt'
#
# the ../proguard-rules.txt should be the location of this file relative to the build.gradle file
#
# You can then build the obfuscated APK using ./gradlew assembleRelease

-keep class * extends android.app.Activity

# --------------------------------------------------------------------
# REMOVE all Log messages except warnings and errors

-assumenosideeffects class android.util.Log {
    public static *** d(...);

    public static *** i(...);
}

Hi Ben,

Thanks for your snippet 😄 Is there any way to ONLY remove log messages without having to config proguard for every single library?
