启动activity

usage: am start [-D] [-W] [-P <FILE>] [--start-profiler <FILE>]
               [--sampling INTERVAL] [-R COUNT] [-S] [--opengl-trace]
               [--user <USER_ID> | current] <INTENT>

am start: start an Activity.  Options are:
    //开启debug模式
    -D: enable debugging
    
    //等待启动完成
    -W: wait for launch to complete

    //将profiler中的结果输出到指定文件中
    --start-profiler <FILE>: start profiler and send results to <FILE>

    //采样，需和start-profiler一起使用
    --sampling INTERVAL: use sample profiling with INTERVAL microseconds
        between samples (use with --start-profiler)

    //和--start-profiler一样，区别在于，在app进入idle状态时profiler结束
    -P <FILE>: like above, but profiling stops when app goes idle

    //重复启动Activity，但每次重复启动都会关闭掉最上面的Activity
    -R: repeat the activity launch <COUNT> times.  Prior to each repeat,
        the top activity will be finished.

    //关闭Activity所属的App进程后再启动Activity
    -S: force stop the target app before starting the activity

    //开启OpenGL tracing
    --opengl-trace: enable tracing of OpenGL functions

    //使用指定的用户来启动activity，如果不输入，则使用当前用户执行
    --user <USER_ID> | current: Specify which user to run as; if not
        specified then run as the current user.

示例：

• -n 使用组件名方式启动照相机功能

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

• -p 先停止目标应用，再启动

C:\Users>adb shell am start -S com.android.camera/.Camera
Stopping: com.android.camera
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.android.camera/.Camera }

• -w 等待应用完成启动

C:\Users>adb shell am start -W com.android.camera/.Camera
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.android.camera/.Camera }
Status: ok
Activity: com.android.camera/.Camera
ThisTime: 295
TotalTime: 295
WaitTime: 314
Complete

• -a Intent加参数

//打开拨号界面，并传递一个DATA_URI数据给拨号界面
am start -a android.intent.action.CALL -d tel:10086

//加Extra, 键值对
adb shell am start -a com.example.bianji.changedata -e lon 31.23037123456 -e lan 121.4737123456

//给特定号码发送短信
C:\Users>adb shell am start -a android.intent.action.SENDTO -d sms:10086 --es sms_body cxye
Starting: Intent { act=android.intent.action.SENDTO dat=sms:xxxxx (has extras) }

//打开某个app的应用信息界面
C:\Users\user>adb shell am start -a android.settings.APPLICATION_DETAILS_SETTINGS -d  package:com.zhihu.android
Starting: Intent { act=android.settings.APPLICATION_DETAILS_SETTINGS dat=package:com.zhihu.android }

• 反编译调试

//微信
adb shell am start -D -W -n com.tencent.mm/com.tencent.mm.ui.LauncherUI

//微博
adb shell am start -D -W -n com.sina.weibo/com.sina.weibo.SplashActivity

其他参数 如 CATEGORY、MIME_TYPE再探讨。

service 与 broadcast

启动service与broadcast用法与activity类似

  //toolAPP中两种方法拷贝文字：
  am broadcast -a com.example.copy.text -e "content" "12345678"
  am startservice  -a com.example.copy.text.second -e  "content" "12345678"
