Varios Proguard nuevas publican los servicios de Google Play v10.2.6 a v11.0.0 en un proyecto Multidex

He actualizado nuestra aplicación para utilizar la versión más reciente del Android Firebase SDK v11.0.0 ( https://firebase.google.com/support/release-notes/android#20170607 ) y de repente aparecen muchos nuevos errores proguard, FYI Todo estaba funcionando bien antes con proguard.

Antes de:

compile 'com.google.firebase:firebase-messaging:10.2.6' compile 'com.google.android.gms:play-services-vision:10.2.6' 

Después:

 compile 'com.google.firebase:firebase-messaging:11.0.0' compile 'com.google.android.gms:play-services-vision:11.0.0' 

El problema es que no parece ser una simple nueva entrada de proguarda desaparecida, pero parece que se rompió todo, de repente varias otras bibliotecas parecían verse afectadas por este cambio.

Estos son los problemas de Proguard relacionados con el GMS:

 Note: the configuration keeps the entry point 'com.google.android.gms.ads.identifier.AdvertisingIdClient { com.google.android.gms.internal.zzfd zza(android.content.Context,com.google.android.gms.common.zza); }', but not the descriptor class 'com.google.android.gms.common.zza' Note: the configuration keeps the entry point 'com.google.android.gms.flags.impl.FlagProviderImpl { void init(com.google.android.gms.dynamic.IObjectWrapper); }', but not the descriptor class 'com.google.android.gms.dynamic.IObjectWrapper' Note: the configuration keeps the entry point 'com.google.android.gms.measurement.AppMeasurement { AppMeasurement(com.google.android.gms.internal.zzchx); }', but not the descriptor class 'com.google.android.gms.internal.zzchx' Note: the configuration keeps the entry point 'com.google.android.gms.measurement.AppMeasurement { void setEventInterceptor(com.google.android.gms.measurement.AppMeasurement$EventInterceptor); }', but not the descriptor class 'com.google.android.gms.measurement.AppMeasurement$EventInterceptor' Note: the configuration keeps the entry point 'com.google.android.gms.measurement.AppMeasurement { void registerOnMeasurementEventListener(com.google.android.gms.measurement.AppMeasurement$OnEventListener); }', but not the descriptor class 'com.google.android.gms.measurement.AppMeasurement$OnEventListener' Note: the configuration keeps the entry point 'com.google.android.gms.measurement.AppMeasurement { void unregisterOnMeasurementEventListener(com.google.android.gms.measurement.AppMeasurement$OnEventListener); }', but not the descriptor class 'com.google.android.gms.measurement.AppMeasurement$OnEventListener' Note: the configuration keeps the entry point 'com.google.android.gms.measurement.AppMeasurement { void registerOnScreenChangeCallback(com.google.android.gms.measurement.AppMeasurement$zza); }', but not the descriptor class 'com.google.android.gms.measurement.AppMeasurement$zza' Note: the configuration keeps the entry point 'com.google.android.gms.measurement.AppMeasurement { void unregisterOnScreenChangeCallback(com.google.android.gms.measurement.AppMeasurement$zza); }', but not the descriptor class 'com.google.android.gms.measurement.AppMeasurement$zza' Note: the configuration keeps the entry point 'com.google.firebase.analytics.FirebaseAnalytics { FirebaseAnalytics(com.google.android.gms.internal.zzchx); }', but not the descriptor class 'com.google.android.gms.internal.zzchx' Note: the configuration keeps the entry point 'com.google.firebase.iid.FirebaseInstanceId { com.google.firebase.iid.FirebaseInstanceId getInstance(com.google.firebase.FirebaseApp); }', but not the descriptor class 'com.google.firebase.FirebaseApp'

Parece que el Android Firebase SDK v11.0.0 está condenado, el Android Firebase SDK v11.0.1 lo arregló sin ningún cambio adicional.

Es posible que desee comprobar este manual de Proguard Resolución de problemas donde se observó que para las advertencias encontradas, the configuration keeps the entry pointbut not the descriptor class :

Su configuración contiene una opción -keep para conservar el método (o campo) dado, pero no la opción -keep para la clase dada que es un tipo de argumento o un tipo de retorno en el descriptor del método. Usted puede entonces desear guardar la clase también. De lo contrario, ProGuard ofuscará su nombre, cambiando así la firma del método. El método podría entonces ser no identificable como un punto de entrada. Puede conservar automáticamente tales clases de descriptor con el modificador de opción -keep includeescriptorclasses (-keep, includedescriptorclasses …). Puede desactivar estas notas especificando la opción -dontnote .

Para obtener información adicional, estas publicaciones de SO también pueden ayudar:

  • Proguard: no se puede encontrar la clase referenciada
  • Proguard no resuelve referencias a clases

En resumen, puede intentar agregar estas dos líneas al archivo de configuración de Proguard:
