I was working on creating a wifi service for my application. When I ran into a strange error detailing "Error receiving broadcast Intent ..." and stating that there was a NullPointerException. I was finally able to track this issue down. What I discovered was a broadcast intent action like WifiManager.WIFI_STATE_CHANGED_ACTION is "sticky". Context.registerReceiver() documentation states that
"The system may broadcast Intents that are "sticky" -- these stay around after the broadcast as finished, to be sent to any later registrations. If your IntentFilter matches one of these sticky Intents, that Intent will be returned by this function and sent to your receiver as if it had just been broadcast." When my broadcastReceiver received the initial sticky broadcast it caused the NullPointerException error. Note I am working on OS1.6 - api level 4 so BroadcastReceiver's isInitialStickyBroadcast() is not available. I hope what I discovered for myself is helpful to others with this error. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
