关键信息解释：

注意关键信息’arm64-v8a’ ABI: ‘arm64’ 这里是指arm64的崩溃，需要找arm64-v8a的符号表，其它符号表按照次逻辑查找。
libil2cpp指libil2cpp.sym.so文件
libunity指libunity.sym.so文件

so文件位置：

有两种获取方式：
1、项目目录下临时目录

{项目编译后路径}\Temp\StagingArea\symbols

2、导出安卓工程的时候，选择Create symbols.zip，此时符号表压缩包会在导出安卓工程目录下面

符号化工具位置：

E:\software\unity\2019.4.30f1\Editor\Data\PlaybackEngines\AndroidPlayer\NDK\toolchains\llvm\prebuilt\windows-x86_64\bin

aarch64-linux-android-addr2line 这个是arm64的
arm-linux-androideabi-addr2line 这个是arm32的

cd到addr2line目录

.\aarch64-linux-android-addr2line.exe -f -C -e C:\Users\jisufeichi\Desktop\symbols\arm64-v8a\libunity.sym.so 0x032cf78 0x032e1a4 0x032fe70 0x0092694
