This is i am getting from ACRA lib init method as we have getAnnotation method in it. I have used -keepattributes *Annotation* and -keep class org.acra.ACRA {*;}

but not any luck...

Does anyone have idea?

Thanks,
Jim.

You may not require to obfuscate ACRA code as it is not a secret library. So you can do something like:

# Keep all the ACRA classes
-keep class org.acra.** { *; }

Or if you are very particular, you could try configuring ACRA using: https://github.com/ACRA/acra/wiki/Proguard by including the following in your config file:

# keep this class so that logging will show 'ACRA' and not a obfuscated name like 'a'.
# Note: if you are removing log messages elsewhere in this file then this isn't necessary
-keep class org.acra.ACRA {
    *;
}

# keep this around for some enums that ACRA needs
-keep class org.acra.ReportingInteractionMode {
    *;
}

-keepnames class org.acra.sender.HttpSender$** {
    *;
}

-keepnames class org.acra.ReportField {
    *;
}

# keep this otherwise it is removed by ProGuard
-keep public class org.acra.ErrorReporter
{
    public void addCustomData(java.lang.String,java.lang.String);
    public void putCustomData(java.lang.String,java.lang.String);
    public void removeCustomData(java.lang.String);
}

# keep this otherwise it is removed by ProGuard
-keep public class org.acra.ErrorReporter
{
    public void handleSilentException(java.lang.Throwable);
}
