两步使用arm-linux-androideabi-addr2line定位JNI动态库中C代码错误位置

1、使用Android Studio调试APP代码时，出现如下错误，很明显是C代码报错了

2、如何定位呢？可以使用SDK目录中的arm-linux-androideabi-addr2line工具，我本地的目录如下：

**androidsdk dk-bundle oolchainsarm-linux-androideabi-4.9prebuiltwindows-x86_64inarm-linux-androideabi-addr2line.exe

使用方法：

第一步：cmd到报错的动态库目录下，位置在obj目录下,并非libs目录下生成的so文件，我的目录是**（项目目录）jnilibsrcmainobjlocalarmeabi**

第二步：使用如下命令定位错误：**androidsdk dk-bundle oolchainsarm-linux-androideabi-4.9prebuiltwindows-x86_64inarm-linux-androideabi-addr2line -C -f -e              libxxx.so 0x#####(address)
