       am get-config

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

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 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.
