几个注意点：
1.Unity BuildSettings中勾选Copy PDB files、Development Build、Autoconnect profiler（自动连接性能分析）、Script Debugging选项。
2.打包程序后，Unity会自动连接Profiler，打开Unity中的Profiler即可查看cpu、gpu、内存等使用情况。
3.在Unity的Console中的Editor会自动连接运行中程序的Debug日志并输出，若没有连接，可尝试输入目标主机的IP地址，来回切换一下Unity界面和程序，验证正常输出日志后，再进行功能调试。
4.在playersetting—>othersetting下的logging，None表示，只显示 日志，不显示跟踪；ScriptOnly:显示日志，并显示脚本调用关系，不显示堆栈信息。
5.Use Player Log选项勾选后，原先在Unity IDE中会输出在Console中的调试信息，会被保存到output_log中，output_log在老版unity(好像是2017之前)会保存在导出XX.exe同路径的XX_Data文件中，新版unity则会保存至C:\user\YourUserName\AppData\LocalLow(或Local)\Company Name\Product Name中，这个文件夹中还保存了一些Crash Report。
6.安卓调试同样适用，使用Usb连接手机后，打开USB调试，可在真机运行的同时，查看profiler及Console日志，Unity界面中Console面板-Editor选择AndroidPlayer。
附上一个Debugger脚本工具，同样适用安卓调试的日志输出。
