Android NDK日志符号化 查找crash原因

例子：

1. 每次发布后，保留　frameworks\runtime-src\proj.android\obj\local\armeabi\lib***.so

   这个 so 是带调试信息的

2. logcat 抓到宕机的文件保存为 a.txt

3. ndk-stack -sym libcocos2dlua.so -dump a1.txt　可以查看宕机的数据

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

Crash dump is completed

4. arm-linux-androideabi-addr2line.exe 可以查看报错的行

C:\Users\zxujie>C:\android-ndk-r10d\toolchains\arm-linux-androideabi-4.8\prebuilt\windows-x86_64\bin\arm-linux-

androideabi-addr2line.exe -e libcocos2dlua.so -a 003362ca

0x003362ca

/Users/Shared/cocos_publish/bigdevil/program/frameworks/runtime-src/proj.android/../../cocos2d-x/cocos//editor-

support/cocostudio/CCArmature.cpp:142

查找闪退，保留几个版本的　proj.android\obj\local\armeabi\libcocos2dlua.so 是比较必要的
