BroadcastReceiver crashes Android application when connection state changes

I have the following code:

 private BroadcastReceiver mConnReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { /* boolean noConnectivity = intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false); String reason = intent.getStringExtra(ConnectivityManager.EXTRA_REASON); boolean isFailover = intent.getBooleanExtra(ConnectivityManager.EXTRA_IS_FAILOVER, false); NetworkInfo currentNetworkInfo = (NetworkInfo) intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO); NetworkInfo otherNetworkInfo = (NetworkInfo) intent.getParcelableExtra(ConnectivityManager.EXTRA_OTHER_NETWORK_INFO); */ // do application-specific task(s) based on the current network state, such // as enabling queuing of HTTP requests when currentNetworkInfo is connected etc. // Toast.makeText(getApplicationContext(), "test", Toast.LENGTH_LONG).show(); // if(!check3G()||!checkWifi()) updateUI(); } }; /* * method to be invoked to register the receiver */ private void registerReceivers() { registerReceiver(mConnReceiver, new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION)); } 

And I register the receiver in the oncreate method like so:

 public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main_menu); registerReceivers(); /* Code omitted*/ } 

And in ondestroy as

 public void onDestroy(){ unregisterReceiver(mConnReceiver); super.onDestroy(); } 

Now whenever the connection state changes, I want to call updateUI();

But when it does change, the function is called, but the application crashes. I am unsure what I am doing wrong and any suggestions would be helpful.

Thanks
