tamaño - La aplicación Android para ofuscar que usa proguard sigue confundiendo los archivos de la biblioteca, ¿o no?
proguard android studio tutorial (2)
Tuve un problema similar cuando proGuard cifró la jsoup lib. Lo arreglé agregando lo siguiente a mi proguard-rules.txt :
-keep class org.jsoup** {
*;
}
Así que el build.gradle terminará con la siguiente sección:
release {
minifyEnabled true
proguardFiles getDefaultProguardFile(''proguard-android.txt''), ''proguard-rules.txt''
}
Soy nuevo en usar Proguard, así que probablemente estoy cometiendo un error de novato. Tengo una aplicación que después de ejecutar la versión de lanzamiento (que utiliza Proguard para ofuscar) se bloquea muy rápidamente. Creo que lo he reducido al hecho de que parece estar ocultando mis bibliotecas de referencia. En mi caso, mis bibliotecas de referencia se usan para definir mis clases de mensajes que estoy usando para comunicarme con otro dispositivo usando Google Protobuffers. Estoy construyendo usando, lanzamiento de hormigas. Mi configuración de programa es:
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-keepclasseswithmembernames class *
{
native <methods>;
}
-keepclasseswithmembernames class *
{
public <init>(android.content.Context, android.util.AttributeSet);
}
-keepclasseswithmembernames class *
{
public <init>(android.content.Context, android.util.AttributeSet, int);
}
-keepclassmembers enum *
{
public static **[] values();
public static ** valueOf(java.lang.String);
}
-keep class * implements android.os.Parcelable
{
public static final android.os.Parcelable$Creator *;
}
En mi archivo ant build.xml tengo definido lo siguiente:

Apreciaría cualquier idea. Copié la mayor parte de mi configuración de compilación y programación de las plantillas en línea, sospecho que en realidad estoy introduciendo a Proguard para ofuscar los archivos de la biblioteca o tengo algo configurado. Estoy viendo la siguiente salida en mi ventana de cmd al final de la compilación:
[proguard] Writing output...

¡Gracias!
Usted ha comentado las directivas de la biblioteca en la configuración de Proguard.
Cambio:
# -libraryjars /libs/protobuf-2.3.0.jar
# -libraryjars /libs/libmessaging.jar
a:
-libraryjars /libs/protobuf-2.3.0.jar
-libraryjars /libs/libmessaging.jar
(y luego no te molestes en definir los archivos de tu biblioteca en tu build.xml)
EDITAR:
Encontré otra manera de hacer que Proguard deje los frascos de la biblioteca solo y pedirle que conservara los nombres de sus paquetes, por ejemplo:
-keep class javax.** { *; }
-keep class org.** { *; }
-keep class twitter4j.** { *; }
