关键点就在最后一句
#47 pc 0000000000003edc /data/app/~~tVaSKAxiJWSXvsD1y19YvA==/com.exemple.test-P6Nt-CeYxb48yv-4c2KiXQ==/lib/arm64/libtest.so (BuildId: e8db9578fbb84b6267d28e3300a51e048bf04d6c)
#47 是调用帧
0000000000003edc 是错误发生的相对偏移地址
/data/app/~~tVaSKAxiJWSXvsD1y19YvA==/com.exemple.test-P6Nt-CeYxb48yv-4c2KiXQ==/lib/arm64/libtest.so 是错误发生的动态库
BuildId:e8db9578fbb84b6267d28e3300a51e048bf04d6c 是动态库的唯一标识。
要还原报错方法的地址就要借助 llvm-addr2line 工具。这个工具一般在 /Users/username/Library/Android/sdk/ndk/21.1.6352462/toolchains/llvm/prebuilt/darwin-x86_64/bin/llvm-addr2line 下面。 然后只要在命令行执行
/Users/username/Library/Android/sdk/ndk/21.1.6352462/toolchains/llvm/prebuilt/darwin-x86_64/bin/llvm-addr2line -e /Users/username/Project/app/build/intermediates/merged_native_libs/Debug/out/lib/arm64-v8a/libtest.so 0x0000000000003edc 就会输出具体的方法地址。
我得到的是：
/Users/username/app/lib/src/main/cpp/Test.cpp:406
所以就是错误发生的代码是在Test.cpp文件的第406行。
