Android设备连接Unity Profiler性能分析器

原网址

Unity提供两种方式让Developer的Android设备连接Profiler进行性能分析：

1、通过wifi，Android设备和计算机处于同一个Wlan中。

2、通过USB ADB

一般情况我们的计算机都是网线，所以我们采用ADB的方式。相比与wifi，ADB也更及时的反应设备性能。

官方的英文文档如下：

http://docs.unity3d.com/Manual/Profiler.html

For ADB profiling, follow these steps:

Attach your device to your Mac/PC via cable and make sure ADB recognizes the device (i.e. it shows in adb devices list).
Check the “Development Build” checkbox in Unity’s build settings dialog, and hit “Build & Run”.
When the app launches on the device, open the profiler window in Unity Editor (Window->Profiler)
Select the AndroidProfiler(ADB@127.0.0.1:54999) from the Profiler Window Active Profiler drop down menu. Note: The Unity editor will automatically create an adb tunnel for your application when you press “Build & Run”. If you want to profile another application or you restart the adb server you have to setup this tunnel manually. To do this, open a Terminal window / CMD prompt and enter adb forward tcp:54999 localabstract:Unityinsert bundle identifier here

Note: The entry in the drop down menu is only visible when the selected target is Android.

If you are using a firewall, you need to make sure that ports 54998 to 55511 are open in the firewall’s outbound rules - these are the ports used by Unity for remote profiling.

按照文档的步骤，这里我来翻译一下：
首先我们先设置ADB：

打开CMD命令行窗口，输入以下命令：

adb forward tcp:54999 localabstract:Unity-com.thisisgame.gamedemo

然后 从Unity中Export Android 工程的时候一定要勾选 Development Build

然后在手机上打开游戏。

打开Unity Profiler窗口选择(ADB@127.0.0.1:54999)

然后就能在Profiler进行性能分析了。
