android how to ensure broadcast receiver receives the first broadcast?

            
As we all know, android broadcast event can be registered to receive many of which broadcast receivers, for example, I signed up for a broadcast system calls, mute the first 10 seconds after handling system calls in onRecevie () where, however, the system comes also broadcast a call, it will trigger the MediaPlayer to play ringtones, so, I can not guarantee that whoever receives the broadcasting system calls, so sometimes appeared before the system comes with a broadcast receiver receives the broadcast (lead first play ringtone) Sometimes I registered a broadcast receiver receives the first broadcast (mute after 10 seconds to play ringtones). How to prevent this randomness there, so I never registered the first received broadcast radio?
PS: setting priorities does not seem to maximum use, there will be random, like, because I suspect the trigger MediaPlayer to play ringtones receiver also set the maximum priority.

However, this player might like telephone system should be the highest priority, there may be a different phone system kernel has been modified have different effects.
