Question

现在，我正在使用适用于WiFi的应用程序，但是当我要访问移动服务提供商网络时，我的应用程序无效。我维护了一个检查网络的后台服务，但是我没有得到如何处理移动和移动到WiFi的网络交换机WiFi？我没有得到如何处理WiFi到移动网络交换机，因为已启用WiFi并且我不在WiFi覆盖区域;在这种情况下，我希望自动切换到移动网络，反之亦然。我的方法如下，不起作用：

String networkStatus = "disconnected";
            int netType = 0;
            try{
            ConnectivityManager connectivityManager =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
            if(connectivityManager != null ){
                    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

                    if(networkInfo != null){
                        netType = networkInfo.getType();
                        Log.d("Log", "connetion is available");
                    }else {
                        Log.d("Log", "connetion is  not available");
                        return networkStatus;
                    }

                //  if(networkInfo.isAvailable()){  // Old one
if(networkInfo.isAvailable() && networkInfo.isConnected()){  // New change added here
                        if(netType == ConnectivityManager.TYPE_WIFI)
                            {}
                        else if(netType == ConnectivityManager.TYPE_MOBILE )
                            {}
                            }
                        }
                    }catch(Exception e){
            Log.d("Log", "checkNetworkConnection" + e.toString());
            return networkStatus;
        }

我已经阅读了许多帖子，听到仍然没有想到。任何人都可以给我任何想法或网址，我可以采用相同的方法实施吗？

先谢谢。

我得到了解决方案：

String networkStatus = "disconnected";
            int netType = 0;
            try{
            ConnectivityManager connectivityManager =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
            if(connectivityManager != null ){
                    NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();

                    if(networkInfo != null){
                        netType = networkInfo.getType();
                        Log.d("Log", "connetion is available");
                    }else {
                        Log.d("Log", "connetion is  not available");
                        return networkStatus;
                    }

                //  if(networkInfo.isAvailable()){  // Old one
if(networkInfo.isAvailable() && networkInfo.isConnected()){  // New change added here
                        if(netType == ConnectivityManager.TYPE_WIFI)
                            {}
                        else if(netType == ConnectivityManager.TYPE_MOBILE )
                            {}
                            }
                        }
                    }catch(Exception e){
            Log.d("Log", "checkNetworkConnection" + e.toString());
            return networkStatus;
        }
