Android后台服务或接收器，用于在后台检查互联网连接,android,service,broadcastreceiver,Android,Service,Broadcastreceiver,在我的应用程序中，我总是在互联网的帮助下连接到openfire服务器。现在，如果连接在这段时间内丢失或断开，我希望它应该弹出一个窗口，按下OK按钮，它应该重新登录此人（就像与服务器的连接丢失一样，即使断开了1秒钟）我正在使用以下代码： public class ConnectionCheck extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) {

在我的应用程序中，我总是在互联网的帮助下连接到openfire服务器。现在，如果连接在这段时间内丢失或断开，我希望它应该弹出一个窗口，按下OK按钮，它应该重新登录此人（就像与服务器的连接丢失一样，即使断开了1秒钟）

我正在使用以下代码：

public class ConnectionCheck extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub

        ConnectivityManager connectivityManager =  (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();
        NetworkInfo mobileNetInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

        if(activeNetInfo!=null){
            Toast.makeText( context, "Active Network Type : " + activeNetInfo.getTypeName(), Toast.LENGTH_SHORT ).show();
        }

         if( mobileNetInfo != null )
            {
              Toast.makeText( context, "Mobile Network Type : " + mobileNetInfo.getTypeName(), Toast.LENGTH_SHORT ).show();
            }

    }

假设wifi断开连接后，它再次连接到移动网络（但在内部，用户未连接到服务器）

我应该怎么做，也就是说，当用户断开连接时——即使是与服务器断开一秒钟，它也会弹出一个窗口

有可能吗

谢谢

-您的上述代码只会检查您的android设备与wifi路由器或手机数据包服务的连接，但它不会检查wifi是否真的有互联网连接。

DRY

（不要重复自己的原则）在这里被滥用了。因此，在生产网络中使用时，请重构代码并将重复的代码转换为方法，即转换为一个

我需要做一些定制的工作…但是我已经准备好了
我的代码在关闭时从Wifi切换到移动网络
我正在使用端口37上的TimeService，以知道当wifi连接仍然打开时，互联网已断开
现在我在这里放了一个完整的工作代码。请原谅，
DRY
（不要重复自己的原则）在这里被滥用了。因此，在生产网络中使用时，请重构代码并将重复的代码转换为方法，即转换为一个
单一的合理位置

/////---------------------------Intial Available Network Checking private boolean checkConnection(){ boolean connected = false; ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); if (cm != null) { NetworkInfo[] netInfo = cm.getAllNetworkInfo(); for (NetworkInfo ni : netInfo) { if ((ni.getTypeName().equalsIgnoreCase("WIFI") || ni.getTypeName().equalsIgnoreCase("MOBILE")) & ni.isConnected() & ni.isAvailable()) { connected = true; } } } return connected; } /////---------------------------Intial Available Network Checking
/////-------------------------------检查工作的Internet连接

public boolean inetAddr(){ boolean x1 = false; try { Socket s = new Socket("utcnist.colorado.edu", 37); InputStream i = s.getInputStream(); Scanner scan = new Scanner(i); while(scan.hasNextLine()){ System.out.println(scan.nextLine()); x1 = true; } } catch (Exception e) { x1 = false; } return x1; } /////-------------------------------Check for the working Internet Connection ////-------------------------------Check Mobile Conectivity Again public boolean mobileConnect(){ boolean conn = false; ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo activeNet = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE); if(activeNet != null){ conn = true; }else{ conn = false; } return conn; } ////------------------------------Check Mobile Conectivity Again
我在这里使用上述方法……

您也可以尝试此服务类。只需将时间间隔设置为秒，并将url设置为ping：

只需记住将服务添加到清单文件，并添加权限

@GauravArora我通常在通过internet拨打电话之前使用此代码，因此您可以在那里使用它以避免不必要的开销，或者如果您愿意，也可以在广播接收器中使用此代码，但那会有点重…但我的情况是不同的兄弟。我想一直检查，因为我的应用程序总是连接到服务器。如果它没有连接到服务器，那么我必须给出一个popup@KumarVivekMitra关于不存在的数据或internet，您提出的另一个问题是，死网络使用url和端口。现在，如果我使用任何url和端口

，那么它应该能工作吗？@GauravArora我通常在通过互联网打电话之前使用此代码，因此您可以在那里使用它以避免不必要的开销，或者如果您愿意，您可以在广播接收器中使用此代码，但这会有点重……但我的情况是，如果不同的兄弟。我想一直检查，因为我的应用程序总是连接到服务器。如果它没有连接到服务器，那么我必须给出一个popup@KumarVivekMitra关于不存在的数据或internet，您提出的另一个问题是，死网络使用url和端口。现在，如果我使用任何url和端口
