Unity Android Bugly 报错地址查询

借助Android NDK arm-linux-androideabi-addr2line.exe 对报错的地址转换成对应代码行。

一、报错信息，例如来自Firebase 报错如下：

Fatal Exception: Tombstone: Version '2020.3.33f1 (915a7af8b0d5)', Build type 'Release', Scripting Backend 'il2cpp', CPU 'armeabi-v7a'

注意关键信息：Backend 'il2cpp' 、CPU 'armeabi-v7a'、与 libunity.so，那我们去找ill2cpp目录下armeabi-v7a目录下libunity.sym.so，注意这里符号表比多了一个sym命名。具体路径在unity安装目录下，参考如下：

xxx\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\il2cpp\Release\Symbols\armeabi-v7a\

二、找到NDK中arm-linux-androideabi-addr2line.exe目录

• xxx\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\

三、执行命令

• arm-linux-androideabi-addr2line.exe -f -C -e so的地址 报错内存地址

• 如上报错示例参考

  arm-linux-androideabi-addr2line.exe -f -C -e libunity.sym.so r0 85f58a00 r1 001fffe9 r2 00000001 r3 001fffdc r4 00000000 r5 00000000 r6 00000010 r7 00020000 r8 00020000 r9 b6cf7ec0 r10 00020010 r11 00001d10 ip 000000ff sp 7c83f188 lr 979c86a9 pc 9807e81a
