Android判断网络是否已经连接

 // check all network connect, WIFI or mobile
 public static boolean isNetworkAvailable(final Context context) {
     boolean hasWifoCon = false;
     boolean hasMobileCon = false;

     ConnectivityManager cm = (ConnectivityManager) context.getSystemService(context.CONNECTIVITY_SERVICE);
     NetworkInfo[] netInfos = cm.getAllNetworkInfo();
     for (NetworkInfo net : netInfos) {

         String type = net.getTypeName();
         if (type.equalsIgnoreCase("WIFI")) {
             LevelLogUtils.getInstance().i(tag, "get Wifi connection");
             if (net.isConnected()) {
                 hasWifoCon = true;
             }
         }

         if (type.equalsIgnoreCase("MOBILE")) {
             LevelLogUtils.getInstance().i(tag, "get Mobile connection");
             if (net.isConnected()) {
                 hasMobileCon = true;
             }
         }
     }
     return hasWifoCon || hasMobileCon;
