Службы Google Play с Proguard в Android Studio

Недавно я перешел от Eclipse к Android Studios. У меня было приложение, использующее Proguard через eclipse, и теперь, когда я двигаюсь, я получаю следующие ошибки.

Ошибка:

Для библиотеки «Picasso» вам просто нужно добавить это в свою конфигурацию ProGuard:

 -dontwarn com.squareup.okhttp.** 

Это связано с тем, что «Picasso» имеет дополнительную библиотеку, которая называется «OkHttp». Это не включено, но не нужно.

Для Служб Google Play существует некоторая несогласованность с библиотекой. Вы должны обновить файлы библиотеки и очистить проект.

Я закончил тем, что поставил следующие строки, так что Proguard перестала предупреждать меня. Сборка по-прежнему выполняется, как ожидалось.

 -dontwarn com.google.android.gms.auth.GoogleAuthUtil -dontwarn com.squareup.picasso.OkHttpLoader
