Google Play Services v23 configurazione Proguard

Question

Dopo l'aggiornamento a Google Play v23 servizi, vedo questo messaggio quando si tenta di esportare domanda firmata in Eclipse:

Proguard returned with error code 1. See console 
Warning: com.google.android.gms.common.GooglePlayServicesUtil: can't find referenced class android.content.pm.PackageInstaller

ho aggiunto questo, come specificato nel documentation

-keep class * extends java.util.ListResourceBundle { 
    protected Object[][] getContents(); 
} 

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable { 
    public static final *** NULL; 
} 

-keepnames @com.google.android.gms.common.annotation.KeepName class * 
-keepclassmembernames class * { 
    @com.google.android.gms.common.annotation.KeepName *; 
} 

-keepnames class * implements android.os.Parcelable { 
    public static final ** CREATOR; 
} 

e provato ad aggiungere

-keep class android.content.pm.PackageInstaller.** 

a proguard-project.txt, ma questo non ha aiutato.

Cosa mi manca?

Answer 1

hey ho avuto lo stesso errore esatto ho riparato con l'aggiunta di:

-keep class com.google.android.gms.** { *; } 
-dontwarn com.google.android.gms.** 

alla mia proguard.cfg

Answer 2

Ho lo stesso problema, ma utilizzando Android Studio. Basato sulla soluzione di Lary Ciminera, ho aggiunto

-dontwarn com.google.android.gms.** 

a proguard-project.txt.

Answer 3

ho riparato aggiungendo questo per Proguard-project.txt:

-keep class android.content.pm.PackageInstaller 
-keep class android.content.pm.PackageInstaller$SessionInfo 
-keep class android.content.pm.PackageManager 

-dontwarn android.content.pm.PackageInstaller 
-dontwarn android.content.pm.PackageInstaller$SessionInfo 
-dontwarn android.content.pm.PackageManager 

-keep class android.webkit.WebSettings 
-dontwarn android.webkit.WebSettings 

Answer 4

Aggiornamento versione di destinazione SDK per almeno 21 dovrebbe risolvere questo problema. PackageInstaller e le classi associate sono state aggiunte nella versione 21 dell'API: https://developer.android.com/reference/android/content/pm/PackageInstaller.html
