背景
版本发布后，收集到到异常上报，有部分记录到是native crash。
而上报的native信息，无法直接定位到错误位置。
解决方案：
一，针对可以复现到场景
1,本地debug版本进行复现，crash复现后找到debug版本的so文件（debug版本的so包含调试信息）
$ find . -name "libitlogin.so" | xargs ls -lhs

可以找到最大的那个so文件，这个so文件会比正常包含在apk中的so文件大N倍，
一般可以在obj/local 或者 debug/ 目录下找到。
2，根据堆栈信息，查找错误。（下面是一个实际发生的错误堆栈）

第一行堆栈信息
#00 pc 006e3136 /data/app/***-kELvojZn3xlCIubKv5Vtsw==/lib/arm/libmoa_content.so
#00 表示堆栈序号
pc 006e3136 表示崩溃发生时 程序计数器 位于 libmoa_content.so 偏移 006e3136 处
3，使用命令查找错误的具体位置。
$ arm-linux-androideabi-addr2line -C -f -e /lib/armeabi-v7a/libmoa_content.so 006e3136
arm-linux-androideabi-addr2line 路径 NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64/bin
二，针对发版后的crash日志收集
针对发版本的apk，需要在编译阶段归档debug类的so文件。 这样在发生crash时候，才能通过归档的so文件来定位到具体的crash位置。
