ofuscar ActionBarSherlock con Proguard

Question

que estoy tratando de ocultar mi aplicación Android usando proguard y ant (eclipse + proguard nunca funciona, siempre falla con error 1). Pero recibo class file ... unexpectedly contains class ... advirtiendo a todos del lugar y la construcción falla. También probé con la opción -ignorewarnings en proguard. La compilación tiene éxito pero obtengo un paquete inutilizable.

Aquí está la salida de hormigas:

¿Cómo puedo solucionar esto?

Answer 1

Asegúrese de que el archivo de configuración Proguard tiene la recommended exclusions para ActionBarSherlock:

-keep class android.support.v4.app.** { *; } 
-keep interface android.support.v4.app.** { *; } 
-keep class com.actionbarsherlock.** { *; } 
-keep interface com.actionbarsherlock.** { *; } 
-keepattributes *Annotation* 

También intente añadir

-keepclassmembers class **.R$* { 
    public static <fields>; 
} 

como se sugiere here.

Answer 2

Cfr. Manual ProGuard> Solución de problemas>Warning: class file ... unexpectedly contains class ...

Se debe especificar el directorio base adecuada en su ruta de clase de entrada: "-injars ...... /clases".
