Usługi Google Play z Proguard w Android Studio

Question

Niedawno przeprowadziłem przejście z Eclipse do Android Studios. Moja aplikacja używa Proguard przez zaćmienie, a teraz, gdy się poruszam, otrzymuję następujące błędy.

Błąd:

ProGuard: [myApp] Warning: com.google.android.gms.auth.GoogleAuthUtil: can't find referenced field 'int auth_client_availability_notification_title' in class com.google.android.gms.R$string

plik Proguard:

# This is a configuration file for ProGuard. 
# http://proguard.sourceforge.net/index.html#manual/usage.html 

-dontusemixedcaseclassnames 
-dontskipnonpubliclibraryclasses 
-verbose 

# Optimization is turned off by default. Dex does not like code run 
# through the ProGuard optimize and preverify steps (and performs some 
# of these optimizations on its own). 
-dontoptimize 
-dontpreverify 
-dontshrink 

# If you want to enable optimization, you should include the 
# following: 
# -optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/* 
# -optimizationpasses 5 
# -allowaccessmodification 
# 
# Note that you cannot just include these flags in your own 
# configuration file; if you are including this file, optimization 
# will be turned off. You'll need to either edit this file, or 
# duplicate the contents of this file and remove the include of this 
# file from your project's proguard.config path property.

Answer 1

Skończyło się na tym, że wprowadziłem poniższe linie, aby Proguard przestał mnie ostrzegać. Kompilacja nadal działa zgodnie z oczekiwaniami.

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

Answer 2

dla biblioteki "Picasso", po prostu trzeba dodać to do konfiguracji PROGUARD:

-dontwarn com.squareup.okhttp.** 

To jest ponieważ "Picasso" posiada opcjonalną bibliotekę "OKHttp". Nie jest to uwzględnione, ale nie jest potrzebne.

W przypadku Usług Google Play wydaje się, że istnieją pewne niespójności z biblioteką. Powinieneś zaktualizować swoje pliki biblioteki i wyczyścić projekt.
