Proguard Retrace无法使用stacktrace运行时信息，例如E/AndroidRuntime(10237):

问题描述

我需要从proguard.trace文件(如E/AndroidRuntime(10237):)中删除行，以使跟踪工作.基本上，我正在查看日志文件，需要删除此行，否则回溯将不起作用.我是否缺少某些东西，还是需要为每个堆栈跟踪执行此操作?基本上，之前的信息会出现在堆栈跟踪行的开头，例如

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

这是整个堆栈跟踪:

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

因此，我正在运行./retrace.sh mapping.txt proguard.retrace，其内容已在上方.除非删除E/AndroidRuntime(10237)，否则它不会回溯:我是否缺少一些回溯选项.如何为此准备跟踪文件?我不认为它是映射文件，因为在删除该行的第一部分后它就可以工作.

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.

推荐答案

Proguard希望将每个"at"放在单独的行中，并且仅在其前面有空格.如果在at之前看到空白以外的任何内容，则不会对其进行模糊处理.

Proguard wants each "at" on a separate line, and only with white space before it. If it sees anything but white space before the at, it will not unobfuscate it.
