am start: start an Activity. Options are:
-D: enable debugging
-W: wait for launch to complete
--start-profiler : start profiler and send results to
--sampling INTERVAL: use sample profiling with INTERVAL microseconds
between samples (use with --start-profiler)
-P : like above, but profiling stops when app goes idle
-R: repeat the activity launch times. Prior to each repeat,
the top activity will be finished.
-S: force stop the target app before starting the activity
--opengl-trace: enable tracing of OpenGL functions
--user | current: Specify which user to run as; if not
specified then run as the current user.
am startservice: start a Service. Options are:
--user | current: Specify which user to run as; if not
specified then run as the current user.
am stopservice: stop a Service. Options are:
--user | current: Specify which user to run as; if not
specified then run as the current user.
am force-stop: force stop everything associated with .
--user | all | current: Specify user to force stop;
all users if not specified.
am kill: Kill all processes associated with . Only kills.
processes that are safe to kill -- that is, will not impact the user
experience.
--user | all | current: Specify user whose processes to kill;
all users if not specified.
am kill-all: Kill all background processes.
am broadcast: send a broadcast Intent. Options are:
--user | all | current: Specify which user to send to; if not
specified then send to all users.
--receiver-permission : Require receiver to hold permission.
am instrument: start an Instrumentation. Typically this target
is the form /. Options are:
-r: print raw results (otherwise decode REPORT_KEY_STREAMRESULT). Use with
[-e perf true] to generate raw output for performance measurements.
-e : set argument to . For test runners a
common form is [-e [,...]].
-p : write profiling data to
-w: wait for instrumentation to finish before returning. Required for
test runners.
--user | current: Specify user instrumentation runs in;
current user if not specified.
--no-window-animation: turn off window animations while running.
--abi : Launch the instrumented process with the selected ABI.
This assumes that the process supports the selected ABI.
am profile: start and stop profiler on a process. The given argument
may be either a process name or pid. Options are:
--user | current: When supplying a process name,
specify user of process to profile; uses current user if not specified.
am dumpheap: dump the heap of a process. The given argument may
be either a process name or pid. Options are:
-n: dump native heap instead of managed heap
--user | current: When supplying a process name,
specify user of process to dump; uses current user if not specified.
am set-debug-app: set application to debug. Options are:
-w: wait for debugger when application starts
--persistent: retain this value
am clear-debug-app: clear the previously set-debug-app.
am bug-report: request bug report generation; will launch UI
when done to select where it should be delivered.
am monitor: start monitoring for crashes or ANRs.
--gdb: start gdbserv on the given port at crash/ANR
am hang: hang the system.
--allow-restart: allow watchdog to perform normal system restart
am restart: restart the user-space system.
am idle-maintenance: perform idle maintenance now.
am screen-compat: control screen compatibility mode of .
am to-uri: print the given Intent specification as a URI.
am to-intent-uri: print the given Intent specification as an intent: URI.
am to-app-uri: print the given Intent specification as an android-app: URI.
am switch-user: switch to put USER_ID in the foreground, starting
execution of that user if it is currently stopped.
am start-user: start USER_ID in background if it is currently stopped,
use switch-user if you want to start the user in foreground.
am stop-user: stop execution of USER_ID, not allowing it to run any
code until a later explicit start or switch to it.
am stack start: start a new activity on using .
am stack movetask: move from its current stack to the top (true) or bottom (false) of .
am stack resize: change size and position to .
am stack list: list all of the activity stacks and their sizes.
am stack info: display the information about activity stack .
am lock-task: bring to the front and don't allow other tasks to run
am get-config: retrieve the configuration and any recent configurations
of the device

[ | | ] 前置条件：
1、首先理解一下这几个概念的意思，参考资料
活动(Activity) - 用于表现功能
服务(Service) - 相当于后台运行的 Activity
广播(Broadcast) - 用于发送广播
广播接收器(BroadcastReceiver) - 用于接收广播
Intent - 用于连接以上各个组件，并在其间传递消息
2、Intent.Action相关知识
am start 启动应用
格式：adb shell am start 包名/.类名
或 adb shell am start 包名/类的全名
后面跟的参数的意思分别是：
| 参数名 | 解释 |
|---|---|
| -a | 传入动作 |
| -n | 传入组件（package） |
| -t | 传入类型 |
| -d | 传入数据 |
1.拨打一个电话：
`am start -a android.intent.action.CALL -d tel:10086`
2.打开一个网页：
am start -a android.intent.action.VIEW -d http://www.baidu.com 3.打开音乐播放器：
adb shell am start -n com.android.bbkmusic/.WidgetToTrackActivity4.启动一个服务：
am startservice <服务名称>
例如：am startservice -n com.android.music/com.android.music.MediaPlaybackService
或者 am startservice -a com.smz.myservice
5.发送一个广播：
am broadcast -a <广播动作>
例如： am broadcast -a com.smz.mybroadcast
6.adb shell am monitor 监控 crash 与 ANR
7.am force-stop , 后跟包名，结束应用
值得注意的是，不同手机的相同类型应用，如相机，因为他们的package都可能是不一样的，所以要把package提取出来，再抽离为公共的方法。
