连接状态更改时，BroadcastReceiver使Android应用程序崩溃

Question

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

Answer 1

It turns out the issue was some legacy code. There was an additional ConnectivityReceiver registered in the Manifest that was never instantiated that was caused the application to crash.

I will post the legacy code shortly.

Thanks for all your help.
