Android Volley Doesn't Work On Local Wifi If 3g/4g Is On

The problem is that as of Android 6.0, if the device is connected to several networks, Android will connect to the one with an internet access, and ignore the other(s). Seems pretty weird, to be polite, but still...

Here is the code I added to make it working:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {

    ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    for (Network net : connectivityManager.getAllNetworks()) {
        NetworkInfo networkInfo = connectivityManager.getNetworkInfo(net);
        if (networkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
            connectivityManager.bindProcessToNetwork(net);
            break;
        }
    }
}
