adb shell am
使用此命令可以从cmd控制台启动 activity, services；发送 broadcast等等：
1 C:UsersAdministrator>adb shell am 2 usage: am [subcommand] [options] 3 4 start an Activity: am start [-D] [-W] <INTENT> 5 -D: enable debugging 6 -W: wait for launch to complete 7 8 start a Service: am startservice <INTENT> 9 10 send a broadcast Intent: am broadcast <INTENT> 11 12 start an Instrumentation: am instrument [flags] <COMPONENT> 13 -r: print raw results (otherwise decode REPORT_KEY_STREAMRESULT) 14 -e <NAME> <VALUE>: set argument <NAME> to <VALUE> 15 -p <FILE>: write profiling data to <FILE> 16 -w: wait for instrumentation to finish before returning 17 18 start profiling: am profile <PROCESS> start <FILE> 19 stop profiling: am profile <PROCESS> stop 20 21 start monitoring: am monitor [--gdb <port>] 22 --gdb: start gdbserv on the given port at crash/ANR 23 24 <INTENT> specifications include these flags: 25 [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>] 26 [-c <CATEGORY> [-c <CATEGORY>] ...] 27 [-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...] 28 [--esn <EXTRA_KEY> ...] 29 [--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...] 30 [-e|--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...] 31 [-n <COMPONENT>] [-f <FLAGS>] 32 [--grant-read-uri-permission] [--grant-write-uri-permission] 33 [--debug-log-resolution] 34 [--activity-brought-to-front] [--activity-clear-top] 35 [--activity-clear-when-task-reset] [--activity-exclude-from-recents] 36 [--activity-launched-from-history] [--activity-multiple-task] 37 [--activity-no-animation] [--activity-no-history] 38 [--activity-no-user-action] [--activity-previous-is-top] 39 [--activity-reorder-to-front] [--activity-reset-task-if-needed] 40 [--activity-single-top] 41 [--receiver-registered-only] [--receiver-replace-pending] 42 [<URI>]
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"
还可以发送命令模拟手机低电环境：
实例：
adb shell am broadcast -a android.intent.action.BATTERY_CHANGED --ei "level" 3 --ei "scale" 100
