adbshellamadbshellam的功能使用此命令从cmd控制台启动活动和服务；发送广播等：C:UsersAdministrator˃adbshellamsage:am[subcommand][options]startanActivity:amstart[-D][-W]-D:enabledebugging-W:waitfora
adb shell am 的功能
adb shell am
使用此命令可以从cmd控制台启动 activity, services；发送 broadcast等等：
C:UsersAdministrator>adb shell am
usage: am [subcommand] [options]
start an Activity: am start [-D] [-W] <INTENT>
-D: enable debugging
-W: wait for launch to complete
start a Service: am startservice <INTENT>
send a broadcast Intent: am broadcast <INTENT>
start an Instrumentation: am instrument [flags] <COMPONENT>
-r: print raw results (otherwise decode REPORT_KEY_STREAMRESULT)
-e <NAME> <VALUE>: set argument <NAME> to <VALUE>
-p <FILE>: write profiling data to <FILE>
-w: wait for instrumentation to finish before returning
start profiling: am profile <PROCESS> start <FILE>
stop profiling: am profile <PROCESS> stop
start monitoring: am monitor [--gdb <port>]
--gdb: start gdbserv on the given port at crash/ANR
<INTENT> specifications include these flags:
[-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>]
[-c <CATEGORY> [-c <CATEGORY>] ...]
[-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...]
[--esn <EXTRA_KEY> ...]

使用实例：
如启动一个 Activity：
格式：
adb shell am start -n 包名/包名＋类名（-n 类名,-a action,-d date,-m MIME-TYPE,-c category,-e 扩展数据,等）。
实例1：
C:UsersAdministrator>adb shell am start -n com.android.camera/.Camera
Starting: Intent { cmp=com.android.camera/.Camera }
Starting: Intent { cmp=com.android.camera/.Camera (has extras) }
Starting: Intent { cmp=com.android.camera/.Camera }
实例2：（带extra 的 intent）
C:UsersAdministrator>adb shell am start -n com.android.camera/.Camera -e abc helloStarting: Intent { cmp=com.android.camera/.Camera (has extras) }
其中 extra 的 key 为 abc ,value 为字串 "hello"
