How to determine whether to connect to the network by programming Android [WiFi and 3G judgment]

This article describes the method of Android programming to determine whether to connect to the network. Share it for your reference, as follows:

Determine whether the wifi network is linked:

public static boolean isWiFiActive(Context inContext) {
     WifiManager mWifiManager = (WifiManager) inContext
     .getSystemService(Context.WIFI_SERVICE);
     WifiInfo wifiInfo = ();
     int ipAddress = wifiInfo == null ? 0 : ();
     if (() && ipAddress != 0) {
     ("**** WIFI is on");
       return true;
     } else {
       ("**** WIFI is off");
       return false;
     }
}

Determine whether the 3G network is linked:

public static boolean isNetworkAvailable( Context context) {
  ConnectivityManager connectivity = (ConnectivityManager) (Context.CONNECTIVITY_SERVICE);
    if (connectivity == null) {
      ("**** newwork is off");
      return false;
    } else {
      NetworkInfo info = ();
      if(info == null){
        ("**** newwork is off");
        return false;
      }else{
        if(()){
          ("**** newwork is on");
          return true;
        }
      }
    }
     ("**** newwork is off");
  return false;
}
