How to reboot emulator to test ACTION_BOOT_COMPLETED?

Question

You can use the following command from adb:

adb shell am activity/service/broadcast -a ACTION -c CATEGORY -n NAME

for example:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n package_name/class_name

Note that class name and package names need to be as defined in the Manifest.

This will generate the Intent you want , directed only to the component you want (otherwise you system will go crazy with BOOT_COMPLETED sent...)

Or another way (also from the command line):

adb shell stop
adb shell start

First, make sure that USB Debugging is enabled from within the emulator:

click:

• the Home icon
• Menu icon
• 'Settings'
• 'Applications'
• 'Development'
• make sure that the box next to 'USB debugging' contains a check mark

from a command-line:

adb -e reboot

EDIT:

This definitely doesn't work... very strange. I tested it and could not make the emulator reboot. It just hangs.

To emulate a broadcast action, you can connect via adb to the emulator/device and open a shell:

adb shell

Then, you can broadcast the action you want to test:

am broadcast -a android.intent.action.BOOT_COMPLETED

Please note that, in the latest Android versions, broadcasting the *android.intent.action.BOOT_COMPLETED* action will actually reboot your emulator/device.
