使用实例：

如启动一个 Activity：

格式：
adb shell am start -n 包名/包名＋类名（-n 类名,-a action,-d date,-m MIME-TYPE,-c category,-e 扩展数据,等）。

实例1：

C:UsersAdministrator>adb shell am start -n com.android.camera/.Camera
Starting: Intent { cmp=com.android.camera/.Camera }

实例2：（带extra 的 intent）

C:UsersAdministrator>adb shell am start -n com.android.camera/.Camera -e abc hello
Starting: Intent { cmp=com.android.camera/.Camera (has extras) }

其中 extra 的 key 为 abc ,value 为字串 "hello"

还可以发送命令模拟手机低电环境：

实例：

adb shell am broadcast -a android.intent.action.BATTERY_CHANGED --ei "level" 3 --ei "scale" 100
