一，工具集成

Logcat是开发者必备的工具，调试app时的闪退，异常，等问题都可以在这里看到。

Android Logcat包是在Unity Editor中显示来自Android设备的堆栈跟踪和日志等消息。

1.1 注意事项

Android Logcat软件包需要Unity 2019.4或更高版本以及Android支持模块。需要添加Android模块：

导入前需要注意：确保你的工程已加载Android模块，并且可以切到Android平台。

确认后在“build Settings”窗口中切换到Android构建目标。

---

1.2 导入插件

在Package Manager(Window” --> PackageManager)界面中导入：

插件简介：

Android Logcat软件包支持：

• Android：日志消息

• Android：应用程序内存统计

• Android：屏幕捕获

• Android：屏幕记录器

• Stacktrace：实用程序

可以通过“Window > Analysis > Android Logcat ”在Unity Editor中访问该窗口。

窗口打开快捷键：Windows 按“Alt+6”；macOS “Option+6”

---

二，连接设备

Android Logcat软件包支持USB和无线连接。本节介绍如何将Android设备连接到Android Logcat窗口。

2.1 使用USB连接

当您打开Android Logcat窗口时，Unity会自动将任何USB连接的Android设备添加到设备列表中。

手机连接上USB之后，需要选择：传输文件。若没有此选项，则需要打开开发者模式。

PS: 在手机版本上多次点击才可以唤醒出开发者模式，再次点击则有吐司提示您已处于开发者模式，这时再去更多设置中去找开发者模式并开启即可。

检测上之后，即可在窗口中看到实时日志了：

2.2 无线连接

要将Android设备连接到Android Logcat窗口：

无线连接，还是得先使用2.1方式使用USB链接一下，然后打开Android Logcat窗口，从工具栏中，选择“设备选择器”。

选择其他连接选项：

在打开的窗口中，找到对应设备点击Connect：

连接成功提示：（不使用USB方式链接，直接输入IP地址，总是链接失败，不知道为什么[\疑惑]）

连接成功后，拔掉USB连接，就可以在可用设备窗口，找到Wifi链接的了：

PS：一次只能连接到一个设备。要选择要连接的设备，请使用Android Logcat窗口中的设备列表。此列表包含已连接设备的设备ID。

可以看到实时日志了：

若需要断开连接，可以在连接窗口对应设备后点击“Disconnect”：

再次连接，直接点最下面的Connect链接，即可链接成功。

三，实用功能介绍

3.1 通用介绍

1. 筛选包名查看日志
   点击No Filter，在弹出的下拉菜单中，即可选择当前运行应用的包名，进行查看当前应用的相关日志：
   

2. 筛选日志信息
   Logcat工具支持在搜索框输入正则表达式检索和区分大小写功能:
   

3. Reconnect重新连接，Disconnect断开链接
   当我们出现一个问题，需要查看日志时，为了防止日志太多将需要查看的日志刷过去，则可以点击Disconnect断开链接，停止捕获更新日志信息。需要再次查看日志时，点击Reconnect重新连接。

3.2 堆栈跟踪工具 – 解析Bugly捕获报错

在Tools下拉菜单下选择Stacktrace Utility 可以打开工具面板：

准备工作：指定符号表）

在Project Setting面板 -> Analysis -> Android Logcat Settings 中设置：

PS：打包时用的哪个就导入哪个，看你打包时的工程设置：Player -> Configuration

若不指定会在解析时报错提示：

At least one symbol path needs to be specified.
Click Configure Symbol Paths and add the necessary symbol path.

举个例子：解析Bugly捕获报错

操作步骤：复制Bugly报错到工具Original界面，然后点击Resolve Stacktraces 即可：
