Android native crash log分析

找到两种方法一种是使用google 的stack工具，一种是使用Analyze android-ndk stack trace.

参考：

android-ndk-stacktrace-analyzer用法

android-ndk/android-ndk-1.6_r1/build/prebuilt/linux-x86/arm-eabi-4.2.1/bin/arm-eabi-objdump -S mylib.so > mylib.asm

python parse_stack.py mylib.asm logcat.txt

举例:

D:\stack>python parse_stack.py libslpi.asm logcat.txt

0x000b7e80: pjsua_acc_unregister + 0x0068

D:\stack>ls

libslpi.asm libslpi.so logcat.txt parse_stack.py stack.py

stack用法:

python stack.py logcat.txt

说明:stack看起来是google内部使用的工具，在windows上跑不起来，需要在Linux环境下，还有使用的时候会提示so文件的位置不存在，按照它的要求，建立相应的目录，并放入so文件就可以了。举例:

root@impjq:~/stack# python stack.py logcat.txt

make: build/core/envsetup.mk: No such file or directory

make: *** No rule to make target `build/core/envsetup.mk'.

pjsua_acc_unregister

指定路径:

root@impjq:~/stack# python stack.py --symbols-dir=. logcat.txt

这样会提示某些lib不存在

按照它的提示，建立相应的目录就可以了，其中libc.so我是直接从ndk里拷贝过来的，这样正常的运行结果如下：

make: build/core/envsetup.mk: No such file or directory

make: *** No rule to make target `build/core/envsetup.mk'. Stop.
