什么是符号表？

符号表是内存地址与函数名、文件名、行号的映射表。符号表元素如下所示：

为什么要配置符号表？

为了能快速并准确地定位用户APP发生Crash的代码位置，Bugly使用符号表对APP发生Crash的程序堆栈进行解析和还原。

第一步：

接入bugly sdk，具体参照bugly官网
符号表位置

第二步：

因为符号表需要so文件，在Editor文件夹下编写获取复制so文件脚本

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEditor.Build;
using UnityEditor.Callbacks;
using System.IO;

        }

        //            break;
        //        }

        //    default:

    }


    const string libpath = "/../Temp/StagingArea/symbols/";

            Debug.Log("sourcefileARM: " + sourcefileARM);
        }
        catch (Exception e)
        {

        CreateDir(symbolsDir + "/arm64-v8a/");

    {
        if (Directory.Exists(path))
            return;

这样打包的时候就会将so文件复制出来 接下来写上传so文件脚本

第三步：

编译apk，这里要注意 要改成IL2CPP模式 不然复制不到so文件

第四步

第三步编辑完成后直接上传so文件
