摘自：http://blog.youkuaiyun.com/u011240877/article/details/51019819 

使用命令adb shell am start -W activity_name

例如：

 adb shell am start -W com.media.painter/com.media.painter.PainterMainActivity
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.media.painter/.PainterMainActivity }
Status: ok
Activity: com.media.painter/.PainterMainActivity
ThisTime: 355
TotalTime: 355
WaitTime: 365
Complete

其中WaitTime就是启动应用总的时间，详细介绍请看原文。
