一、在Android开发中，我们经常遇到以下错误：

其中backtrace下面就是报错的位置二、找到出错的内存地址
这里我们就找到了“libnative-lib.so”的错误地址是“00013e86”，这样就定位到了C++代码出错的地址了。
三、转换获取出错的具体文件和行数，下面是完成执行命令
G:\wangqi\AndroidStudio\Android\Sdk\android-ndk-r16b\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin> .\arm-linux-androideabi-addr2line.exe -C -f -e G:\wangqi\work\a8541camera2Push\app\build\intermediates\cmake\debug\obj\armeabi-v7a\libnative-lib.so 00013bb7
