I need to remove lines from my proguard.trace file like E/AndroidRuntime(10237): in order for retrace to work. Basically I am looking at log file and need to remove this lines or retrace does not work. Am I missing something or do I need to do this for every stacktrace? Basically its the information before that appears at the beginning of a stacktrace line like

```
 E/AndroidRuntime(10237):  at com.test.a.b.c(UnnownSource) :134

```

Here is the whole stacktrace:

```
E/AndroidRuntime(10237): FATAL EXCEPTION: main
E/AndroidRuntime(10237): java.lang.ArithmeticException: divide by zero
E/AndroidRuntime(10237):    at ub.a(SourceFile:180)
E/AndroidRuntime(10237):    at wp.getView(SourceFile:290)

E/AndroidRuntime(10237):    at android.app.ActivityThread.main(ActivityThread.java:4627)
E/AndroidRuntime(10237):    at java.lang.reflect.Method.invokeNative(Native Method)
E/AndroidRuntime(10237):    at java.lang.reflect.Method.invoke(Method.java:521)
E/AndroidRuntime(10237):    at  com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:858)
E/AndroidRuntime(10237):    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)
E/AndroidRuntime(10237):    at dalvik.system.NativeStart.main(Native Method)
      etc
E/        ( 2623): Dumpstate > /data/log/dumpstate_app_error

```

So I am running ./retrace.sh mapping.txt proguard.retrace the contents of which is above. It will not retrace unless I remove E/AndroidRuntime(10237): 
Am I missing some options to retrace. How do trace files need to be prepared for this to work? I don't think its the mapping file because it works after I remove the first part of the line.
