Answer 1

You don't have to use any API for connect to wifi its only requires if you want to manually start your wifi in device,

Just make sure your device has a WiFi enable, and make a simple TCP/IP Socket application. With this you can communication with your system and device, And Use System's public IP to connect with your system.

Also don't forget to give permission Internet in your manifest file..
