注意关键信息'arm64-v8a' ABI: 'arm64' 这里指arm64的崩溃，找对应的arm64-v8a的符号表，其他符号表依这个逻辑查找;libil2cpp指libil2cpp.sym.so文件，libunity指libunity.sym.so
so 文件位置:项目导出cache路径下
{项目编译后路径}\Temp\StagingArea\symbols
在unity的安装目录下找到addr2line
D:\Program Files\Unity\2020.3.33f1\Editor\Data\PlaybackEngines\AndroidPlayer\NDK\toolchains\llvm\prebuilt\windows-x86_64\bin

执行命令
aarch64-linux-android-addr2line.exe 这个是arm64的
arm-linux-androideabi-addr2line.exe 这个是arm32的
cd 到addr2line.exe目录
.\aarch64-linux-android-addr2line.exe -f -C -e C:\Users\xxx\Downloads\arm64-v8a\libunity.sym.so 0x2fa89c 0x418288 0x417f38 0x407010 0x406660 0x874aac 0x577224 0x57748c 0x3c92f0 0x3b4190 0x3b4d40 0x3cb078
