The Startup method is

$ adb shell

The entry class of the program can be obtained from each application's Androidmanifest.xml file, with the calculator (calculator) as an example, its

Package= "Com.android.calculator2" ...

The starting method for this calculator (calculator) is:

# AM Start-n com.android.calculator2/com.android.calculator2.calculator

For the helloactivity example project, Androidmanifest.xml looks like this:

Package= "Com.example.android.helloactivity" ...>

The starting method for this is:

# AM Start-n com.example.android.helloactivity/com.example.android.helloactivity.helloactivity

Some of the other application startup commands are as follows:

The calendar is started by:

# AM Start-n com.android.calendar/com.android.calendar.launchactivity

AlarmClock (alarm) is started by:

# AM Start-n Com.android.alarmclock/com.android.alarmclock.alarmclock

As a general rule, an Android app corresponds to a project. It is worth noting that some projects have multiple activities, while others use a project. For example: In the Android interface, music and video are two applications, but they use the Packages/apps/music project. In this project, the Androidmanifest.xml file contains different activities.


The starting methods for music and video are:

# AM Start-n com.android.music/com.android.music.musicbrowseractivity

# AM Start-n com.android.music/com.android.music.videobrowseractivity

# AM Start-n com.android.music/com.android.music.mediaplaybackactivity


The camera startup method is:

# AM Start-n Com.android.camera/com.android.camera.camera


The Browser (browser) Startup method is:

# AM Start-n com.android.browser/com.android.browser.browseractivity
