[android-developers] Broadcast Receiver

I have created a simple Broadcast Receiver and it working absolutely fine except that if i turned on/off the Air Plane Mode,
it is taking nearly 150 seconds to receive the broadcasted message using onReceive(). Another thing is only this is causing a
problem if we launch the application and then if i change Air plane Mode (on/off), Then it taking too long to receive the message.


*** If there is Mode change before launching the application it didn't affect the time to receive the message in onReceive().

I have attached the sample project with in this topic.
