ProGuard has removed the optional attributes SourceFile and LineNumberTable from the obfuscated application. As a result, the stack traces don't have line numbers, causing some ambiguity. ReTrace prints out a list of possible alternatives for each line of the stack trace.
You can get stack traces that are easier to interpret by adding the following lines to your proguard-project.txt
:
-renamesourcefileattribute MyApplication
-keepattributes SourceFile,LineNumberTable
