My Service is running in standby but only if USB is connected. Why?

I have created (i'm a noob!!!!) a good app that use a service开发者_JS百科 to do some periodic operations.

When the phone is connected to pc via USB (using eclipse with device connected) during test, the service run even in stadby, in the best way possible.

I can see it in logcat and by the result operation...

But when the phone is disconnected the service is running only if the phone is wake up!

How i can solve it without wakelock ?

I mean obtain something like RADIO FM, understand? ;-)

Thanx to all friends!

That is probably because the device is not actually in "standby".

You can't.

Use AlarmManager and something like my WakefulIntentService for this.

Android does not have "RADIO FM".
