1.You have to host your website on a server before you can access it from your phone.
2.If you want to access your website without hosting you have to connect your Android phone to the same network.You don’t need to change the servername.
3.Change your servername back to default and try turning off the firewall and change hostname to the IP of your machine.
Ex define(‘DB_HOST’,’localhost’);
to:
define(‘DB_HOST’,’192.168.0.4′);
