Android如何定位JNI错误行数

1.ndk-stack.cmd位置
   M:\Android\Sdk\ndk\21.1.6352462
2.aarch64-linux-android-addr2line.exe位置
   M:\Android\Sdk\ndk\21.1.6352462\toolchains\aarch64-linux-android-4.9\prebuilt\windows-x86_64\bin

本文用的是arm64架构的，如果是其它架构，注意自己根据当前电脑环境将这两个位置加入到path环境变量中

1.用ndk-stack得到错误信息的具体内存地址

rem 注意，native的so库需要merged_native_libs目录里的而不是stripped_native_libs目录里的，stripped拿不到c++错误的具体位置的，得到的c++位置是?:??
adb logcat | ndk-stack -sym D:\ASProject\SurfaceWork\app\build\intermediates\merged_native_libs\debug\out\lib\arm64-v8a > ndkdump.txt

2.打开ndkdump.txt拿到出错的内存地址0x0000000000000a84, 注意报错地址后面一般是我们出错的.so文件（这一步其实应该可以直接拿到了我们cpp错误信息了，例如surfacework.cpp:46:41表示surfacework.cpp文件第46行41列这个位置，主要关注行数，列数可能会存在偏差）

3.使用addr2line拿到出错的cpp文件信息和具体的行数

aarch64-linux-android-addr2line -f -C -e D:\ASProject\SurfaceWork\app\build\intermediates\merged_native_libs\debug\out\lib\arm64-v8a\libsurfacework.so 0x0000000000000a84
