        -e <NAME> <VALUE>: set argument <NAME> to <VALUE>
        -p <FILE>: write profiling data to <FILE>
        -w: wait for instrumentation to finish before returning

    start profiling: am profile <PROCESS> start <FILE>

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

 

实例2：（带extra 的 intent）

C:\Users\Administrator>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"
