一，工具集成
Logcat是開發者必備的工具，調試app時的閃退，異常，等問題都可以在這里看到。
Android Logcat包是在Unity Editor中顯示來自Android設備的堆棧跟蹤和日志等消息。
1.1 注意事項
Android Logcat軟件包需要Unity 2019.4或更高版本以及Android支持模塊。需要添加Android模塊：
導入前需要注意：確保你的工程已加載Android模塊，并且可以切到Android平臺。
確認后在“build Settings”窗口中切換到Android構建目標。
1.2 導入插件
在Package Manager(Window” --> PackageManager)界面中導入：
插件簡介：
Android Logcat軟件包支持：
Android：日志消息
Android：應用程序內存統計
Android：屏幕捕獲
Android：屏幕記錄器
Stacktrace：實用程序
可以通過“Window > Analysis > Android Logcat ”在Unity Editor中訪問該窗口。
窗口打開快捷鍵：Windows 按“Alt+6”；macOS “Option+6”
二，連接設備
Android Logcat軟件包支持USB和無線連接。本節介紹如何將Android設備連接到Android Logcat窗口。
2.1 使用USB連接
當您打開Android Logcat窗口時，Unity會自動將任何USB連接的Android設備添加到設備列表中。
手機連接上USB之后，需要選擇：傳輸文件。若沒有此選項，則需要打開開發者模式。
PS: 在手機版本上多次點擊才可以喚醒出開發者模式，再次點擊則有吐司提示您已處于開發者模式，這時再去更多設置中去找開發者模式并開啟即可。
檢測上之后，即可在窗口中看到實時日志了：

2.2 無線連接
要將Android設備連接到Android Logcat窗口：
無線連接，還是得先使用2.1方式使用USB鏈接一下，然后打開Android Logcat窗口，從工具欄中，選擇“設備選擇器”。
選擇其他連接選項：
在打開的窗口中，找到對應設備點擊Connect：
連接成功提示：（不使用USB方式鏈接，直接輸入IP地址，總是鏈接失敗，不知道為什么[\疑惑]）
連接成功后，拔掉USB連接，就可以在可用設備窗口，找到Wifi鏈接的了：
PS：一次只能連接到一個設備。要選擇要連接的設備，請使用Android Logcat窗口中的設備列表。此列表包含已連接設備的設備ID。
可以看到實時日志了：
若需要斷開連接，可以在連接窗口對應設備后點擊“Disconnect”：
再次連接，直接點最下面的Connect鏈接，即可鏈接成功。
三，實用功能介紹
3.1 通用介紹
1.篩選包名查看日志
點擊No Filter，在彈出的下拉菜單中，即可選擇當前運行應用的包名，進行查看當前應用的相關日志：
2.篩選日志信息
Logcat工具支持在搜索框輸入正則表達式檢索和區分大小寫功能:
3.Reconnect重新連接，Disconnect斷開鏈接
當我們出現一個問題，需要查看日志時，為了防止日志太多將需要查看的日志刷過去，則可以點擊Disconnect斷開鏈接，停止捕獲更新日志信息。需要再次查看日志時，點擊Reconnect重新連接。
3.2 堆棧跟蹤工具 – 解析Bugly捕獲報錯
在Tools下拉菜單下選擇Stacktrace Utility 可以打開工具面板：
準備工作：指定符號表）
在Project Setting面板 -> Analysis -> Android Logcat Settings 中設置：
PS：打包時用的哪個就導入哪個，看你打包時的工程設置：Player -> Configuration

若不指定會在解析時報錯提示：
At least one symbol path needs to be specified.
Click Configure Symbol Paths and add the necessary symbol path.
舉個例子：解析Bugly捕獲報錯
操作步驟：復制Bugly報錯到工具Original界面，然后點擊Resolve Stacktraces 即可：
