am命令作用：管理Activity 
usage: am [start|broadcast|instrument|profile] 
am start -D INTENT 
am broadcast INTENT 
am instrument [-r] [-e <ARG_NAME> <ARG_VALUE>] [-p <PROF_FILE>] 
[-w] <COMPONENT> 
am profile <PROCESS> [start <PROF_FILE>|stop] 
INTENT is described with: 
[-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>] 
[-c <CATEGORY> [-c <CATEGORY>] ...] 
[-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...] 
[--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...] 
[-e|--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...] 
[-n <COMPONENT>] [-f <FLAGS>] [<URI>] 
The start command starts activity. Use -D option to make 'DebugOption' true. 
The broadcast command sends broadcast. 
The instrument command starts instrumentation. 
Use -r option to make 'rawMode' true.

打开一个应用可以adb shell进去命令模式之后，

再运行

am start -n 包名/应用名

包名和应用名可以在Androidmanifest.xml文件查看到

例如打开应用程序可以使用命令：

am start -n com.android.settings/com.android.settings.ApplicationSettings
