Question

I want to do something when the mobile device is closing, but I don’t know what is the method; could you tell me how to detect if mobile device is shutting down?

I know the method about mobile restart android.intent.action.BOOT_COMPLETED, but I cannot find similar power off.

Answer 1

http://developer.android.com/reference/android/content/Intent.html#ACTION_SHUTDOWN

public static final String
ACTION_SHUTDOWN

Since: API Level 4 Broadcast Action:
Device is shutting down. This is
broadcast when the device is being
shut down (completely turned off, not
sleeping). Once the broadcast is
complete, the final shutdown will
proceed and all unsaved data lost.
Apps will not normally need to handle
this, since the foreground activity
will be paused as well. This is a
protected intent that can only be sent
by the system.

Constant Value:
“android.intent.action.ACTION_SHUTDOWN”

This would appear to be it? I just Googled your command and it was on the Standard Broadcast Actions list. 🙂
