adb shell am使用此命令可以從cmd控制台啟動 activity, services；發送 broadcast等等： 

 1 C:\Users\Administrator>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 returning17 18     start profiling: am profile <PROCESS> start <FILE>19     stop profiling: am profile <PROCESS> stop20 21     start monitoring: am monitor [--gdb <port>]22         --gdb: start gdbserv on the given port at crash/ANR23 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>]

 

使用執行個體：如啟動一個 Activity： 

格式：adb shell am start -n 包名/包名＋類名（-n 類名,-a action,-d date,-m MIME-TYPE,-c category,-e 擴充資料,等）。

執行個體1：

C:\Users\Administrator>adb shell am start -n com.android.camera/.Camera
Starting: Intent { cmp=com.android.camera/.Camera }
 執行個體2：（帶extra 的 intent）C:\Users\Administrator>adb shell am start -n com.android.camera/.Camera -e abc hello
Starting: Intent { cmp=com.android.camera/.Camera (has extras) }其中 extra 的 key 為 abc ,value 為字串 "hello" 還可以發送命令類比手機低電環境：

執行個體：

adb shell am broadcast -a android.intent.action.BATTERY_CHANGED --ei "level" 3 --ei "scale" 100
