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

我有以下代码：

    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));
       }

我在oncreate方法中注册接收器，如下所示：

   public void onCreate(Bundle savedInstanceState) {

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

在ondestroy作为

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

现在，每当连接状态改变时，我都要调用updateUI（）

但当它确实发生更改时，会调用该函数，但应用程序会崩溃。我不确定我做错了什么，任何建议都会有帮助

谢谢

原来问题是一些遗留代码。清单中还注册了一个从未实例化的ConnectionTyReceiver，导致应用程序崩溃

我将很快发布遗留代码

感谢您的帮助。

请发布stacktrace和updateUI方法的内容。我认为updateUI方法中没有问题，因为它也会在我的测试土司上崩溃。尽管如此，我还是会发布代码和堆栈跟踪。@AviC:ConnectivityReceiver.class在哪里？？确保您已将其正确注册到清单中或添加到正确的包中。我认为，如果您以编程方式添加了broadcastreceiver，您就不必将其添加到清单中。这可能是问题所在-你能帮我修改代码吗？我必须这样做才能确保它按预期工作？请发布stacktrace和updateUI方法的内容。我不认为updateUI方法存在问题，因为它也会在我的测试土司上崩溃。尽管如此，我还是会发布代码和堆栈跟踪。@AviC:ConnectivityReceiver.class在哪里？？确保您已将其正确注册到清单中或添加到正确的包中。我认为，如果您以编程方式添加了broadcastreceiver，您就不必将其添加到清单中。这可能是个问题——你能帮我修改代码吗？我必须这样做才能确保它按预期工作？
