I have two devices one is going to share internet the other one is going to connect to the network of the device to enter the internet. What I want is to send information (a link) to the devices that connect to the android that shares the internet but I need only the device that shares the internet is the only one that you have to program an application to perform this function. I thought of something similar to the hotels where you connect and when you open the browser opens an authentication page, in my case I would show the page I want.
As an alternative, how else could you send the link without using bluetooth or have to ask your phone number or tell it to enter a specific page?
