am start: start an Activity.  Options are:
    -D: enable debugging
    -W: wait for launch to complete
    --start-profiler <FILE>: start profiler and send results to <FILE>
    -P <FILE>: like above, but profiling stops when app goes idle
    -R: repeat the activity launch <COUNT> 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 <USER_ID> | current: Specify which user to run as; if not
        specified then run as the current user.

am startservice: start a Service.  Options are:
    --user <USER_ID> | current: Specify which user to run as; if not
        specified then run as the current user.

am force-stop: force stop everything associated with <PACKAGE>.
    --user <USER_ID> | all | current: Specify user to force stop;
        all users if not specified.

am kill: Kill all processes associated with <PACKAGE>.  Only kills.
  processes that are safe to kill -- that is, will not impact the user
  experience.
    --user <USER_ID> | 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 <USER_ID> | all | current: Specify which user to send to; if not
        specified then send to all users.
    --receiver-permission <PERMISSION>: Require receiver to hold permission.

am instrument: start an Instrumentation.  Typically this target <COMPONENT>
  is the form <TEST_PACKAGE>/<RUNNER_CLASS>.  Options are:
    -r: print raw results (otherwise decode REPORT_KEY_STREAMRESULT).  Use with
        [-e perf true] to generate raw output for performance measurements.
    -e <NAME> <VALUE>: set argument <NAME> to <VALUE>.  For test runners a
        common form is [-e <testrunner_flag> <value>[,<value>...]].
    -p <FILE>: write profiling data to <FILE>
    -w: wait for instrumentation to finish before returning.  Required for
        test runners.
    --user <USER_ID> | current: Specify user instrumentation runs in;
        current user if not specified.
    --no-window-animation: turn off window animations will running.

am profile: start and stop profiler on a process.  The given <PROCESS> argument
  may be either a process name or pid.  Options are:
    --user <USER_ID> | 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 <PROCESS> argument may
  be either a process name or pid.  Options are:
    -n: dump native heap instead of managed heap
    --user <USER_ID> | current: When supplying a process name,
        specify user of process to dump; uses current user if not specified.

am set-debug-app: set application <PACKAGE> 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 screen-compat: control screen compatibility mode of <PACKAGE>.

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 switch-user: switch to put USER_ID in the foreground, starting
  execution of that user if it is currently stopped.

am stop-user: stop execution of USER_ID, not allowing it to run any
  code until a later explicit switch to it.
