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

am startservice: start a Service.

am force-stop: force stop everything associated with <PACKAGE>.

am kill: Kill all processes associated with <PACKAGE>.  Only kills.
  processes that are safe to kill -- that is, will not impact the user
  experience.

am kill-all: Kill all background processes.

am broadcast: send a broadcast Intent.

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.
    --no-window-animation: turn off window animations will running.

am profile: start and stop profiler on a process.

am dumpheap: dump the heap of a process.  Options are:
    -n: dump native heap instead of managed heap

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 monitor: start monitoring for crashes or ANRs.
    --gdb: start gdbserv on the given port at crash/ANR

am screen-compat: control screen compatibility mode of <PACKAGE>.

am display-size: override display size.

am to-uri: print the given Intent specification as a URI.

am to-intent-uri: print the given Intent specification as an intent: URI.
