'ndk-stack' is a simple tool that allows you to analyze stack traces as they appear in the output of 'adb logcat' and replace any address inside a shared library with the corresponding:values.

In the output of 'adb logcat', you may see something like the followings, and we must translate those:

I/DEBUG   (   31): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
I/DEBUG   (   31): Build fingerprint: 'generic/google_sdk/generic/:2.2/FRF91/43546:eng/test-keys'

How to use this tool

If you succeed in building Cocos2d-x android project, it will generate shared libraries in $PROJECT_PATH/obj/local/abi, where 'abi' stands for your device's ABI (i.e.'armeabi' by default);

You can feed the logcat text either as direct input to the program, e.g.:

adb logcat | $NDK/ndk-stack -sym $PROJECT_PATH/obj/local/armeabi

Or you can use the -dump option to specify the logcat as an input file, e.g.:

adb logcat > /tmp/foo.txt
$NDK/ndk-stack -sym $PROJECT_PATH/obj/local/armeabi -dump foo.txt

After that, you will get the more readable output:

********** Crash dump: **********

Stack frame #06  pc 0000d362  /system/lib/libc.so

IMPORTANT

The tool looks for the initial line containing starts in the logcat output, i.e.something this looks like:

*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***

When copy/pasting traces, don't forget this line from the traces, or ndk-stack won't work correctly.

Now both the versions(linux/windows/mac) of ndk-stack are available at Android Developer .
