bug after obfuscating android app with ACRA

Question

After obfuscating with proguard using ADT I have the following error when executing the app:

05-20 19:59:20.158: E/AndroidRuntime(14515): FATAL EXCEPTION: main 
05-20 19:59:20.158: E/AndroidRuntime(14515): java.lang.NoSuchFieldError: PUT

It seems to be due to missing acra libraries. The progaurd-project.txt is:

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose
-dontoptimize
-dontpreverify

-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService

-keepclassmembers public class * extends android.view.View {

}

# We want to keep methods in Activity that could be used in the XML attribute onClick

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations

-keepclassmembers class **.R$* {

}

How could I exclude the obfuscation off all external libraries?, to prevent these type of errors.

Answer 1

I don't know of a way to prevent obfuscation of all external libs, but hopefully this doc will get you past your ACRA-specific issues.

In general, most Android 3rdparty libs will include a section in their documentation about how to configure Proguard to play nice with the lib.
