Android: Detect touch from service

Question

I am trying to find a way to detect when a user touches the screen in any way while my services is running in the background. For example, I want to be able to detect when a user presses on an app icon on the home screen. Is this possible and if so how would it be implemented?

Please see this explanation of services. You should be able to send a message to your service using a Messenger. So on your onClick event you will call your messenger ... example:

        try {
            Message msg = Message.obtain(null,
                    MessengerService.MSG_BUTTON_CLICKED);
            msg.replyTo = mMessenger;
            mService.send(msg);

            // Give it some value as an example.
            msg = Message.obtain(null,
                    MessengerService.MSG_SET_VALUE, this.hashCode(), 0);
            mService.send(msg);
        } catch (RemoteException e) {
            // In this case the service has crashed before we could even
            // do anything with it; we can count on soon being
            // disconnected (and then reconnected if it can be restarted)
            // so there is no need to do anything here.
        }
