Java – use Proguard to confuse actionbarsherlock

I'm trying to blur my Android application with Proguard and ant (eclipse Proguard never works, always fails, error 1) But I'm getting class files... Accidentally containing classes... Warning all places and build failures I also tried to use the - ignore warnings option in Proguard The build succeeded, but I got a package that I couldn't use

This is the ant output:

-post-compile:

How can I solve it?

Solution

Ensure that your Proguard profile has recommended exclusions for actionbarsherlock:

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

Also try adding

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