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\ndk-bundle\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-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）\jnilib\src\main\obj\local\armeabi\**
第二步：使用如下命令定位错误：**\androidsdk\ndk-bundle\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-addr2line -C -f -e libxxx.so 0x#####(address)
