getAllNetworkInfo detect wifi or mobile connection, but never both

Question

I have a function which check network connections using:

ConnectivityManager cm = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo[] networkInfos = cm.getAllNetworkInfo();

but, as soon the Wifi network is connected, the mobile network is given as DISCONNECTED

How could I know if both networks are connected?

Thanks in advance for your time.

Answer 1

Try this:

ConnectivityManager cm = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
NetworkInfo wifi = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
NetworkInfo mobileNet = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if(netInfo!=null){
  if(mobileNet.isConnected()){
    System.out.println("Mobile Network is connected");

  }
  if(wifi.isConnected()){
    System.out.println("Wi-fi Network is connected");
  }

}

How could I know if both networks are connected?

You can create for sure method that will check for both types e.q.

if (networkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
   // do your stuff
}
if (networkInfo.getType() == ConnectivityManager.TYPE_MOBILE) {
   // do your stuff
}

But in Android OS, if Wifi and Mobile network is available (and you can connect to), OS will choose Wifi by default so it'll use Wifi as active network connection.
