        -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
 
    <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> ...]
        [--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...]
        [-e|--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...]
        [-n <COMPONENT>] [-f <FLAGS>]
        [--grant-read-uri-permission] [--grant-write-uri-permission]
        [--debug-log-resolution]
        [--activity-brought-to-front] [--activity-clear-top]
        [--activity-clear-when-task-reset] [--activity-exclude-from-recents]
        [--activity-launched-from-history] [--activity-multiple-task]
        [--activity-no-animation] [--activity-no-history]
        [--activity-no-user-action] [--activity-previous-is-top]
        [--activity-reorder-to-front] [--activity-reset-task-if-needed]
        [--activity-single-top]
        [--receiver-registered-only] [--receiver-replace-pending]
        [<URI>]


'''使用举例:'''<br>
 am start -n com.google.android.browser/com.google.android.browser.BrowserActivity
 am start -a android.intent.action.VIEW -d http://www.google.com/
 am start -a android.intent.action.CALL -d tel:123456789


设置
 am start -n com.android.settings/com.android.settings.Settings


am实际上是对[[app_process]]的一个简单的脚本封装。整个am源码如下所示：

<source lang="bash">
cat am
# Script to start "am" on the device, which has a very rudimentary
# shell.
#
base=/system
export CLASSPATH=$base/framework/am.jar
exec app_process $base/bin com.android.commands.am.Am "$@"
</source>
