This simple script acts as a filter to adb logcat and resolves addresses and
libraries in native stack traces by their corresponding symbol and originating
source file line. Simply put, it turns this:
I/DEBUG ( 80): #00 pc 00011070 /system/lib/libc.so
...
I/DEBUG ( 80): #12 pc 0001cdc6 /system/lib/libsurfaceflinger.so
into this:
I/DEBUG ( 80): #00 pthread_mutex_lock bionic/libc/bionic/pthread.c:1022
...
I/DEBUG ( 80): #12 android::LayerBase::drawWithOpenGL(android::Region const&, android::Texture const&) const frameworks/base/services/surfaceflinger/LayerBase.cpp:486
Simply pipe the output of adb logcat into this script:
$ adb logcat |logcatresolve.py
This script requires a couple of environment variables to be declared. They
are usually set by the Android configuration macros, e.g. lunch or
choosecombo, so if you set them according to the build you are using you
should be able to use it directly. The configuration must also be built.
It simply calls addr2line on the right library file in your build directory
to lookup the symbol corresponding to the stack trace addresses and replaces
them with the output.
