[android-developers] broadcast receiver priority question

the symptom: I have a broadcast receiver that listen to sms, when a
sms is received, i call an activity to display.

It works all fine if the screen is on and not locked.

But when screen is locked, and as soon as i received the sms, the
activity popup for a second then disappeared.

and I use the code to unlock the screen

getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
| WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);

I think it might be the competitions with phone default sms program
( the sms default program shows a notification only). I am wondering
is there a way to set priority to broadcast receivers or even the
activity that receiver stared, to avoid the conflicts between multiple
receivers. or set orders to execute one by one?

I have tried to thread.sleep my receiver for a second, still not
working. Any idea to solve the issue? help please.

Thanks a lot.

Kev
