ProGuard rules for using Dagger 1.1.0 with gradle.

build.gradle

dependencies {
  def dagger_version = "1.1.0"
  compile "com.squareup.dagger:dagger:${dagger_version}"
  compile "com.squareup.dagger:dagger-compiler:${dagger_version}"
}

Just tried with dagger 1.2, does not work. Still getting a lot of proguard errors.

This is insufficient for Dagger 1.2 as module reflective fall-back was disabled, and the string-keys that Dagger uses are not obfuscatable. It should work for mere unused-code-stripping, but not for obfuscation.

Side note - you should do "-keepattributes Signature" as well if you have any generics.
