WiFi hotspot isn't recognised on Android 13

[gnarea]

It works fine on Android 11, and I don't have an Android 12 phone but I'm sure it worked fine there too before the Android 13 upgrade.

Note that the WiFi hotspot is on as can be seen at the top.

The solution implemented in this PR is relying on the exception occurrence: We noticed that when the hotspot is off, the request for local IP addresses would throw an exception, and with this result, we know if the hotspot is on/off.

This is not the most elegant solution because instead of an exception, we should return a state (if an IP list is returned or not). Also, this is not ideal because we are relying on a behavior that is not documented, so we can not trust that this is a stable solution (as we can't test in all devices/scenarios).

And, above all, this solution is not in line with what is done up to API 32: the system reporting hotspot state changes.

In my investigation, I found that in API 33 there were changes in the way an application interacts with the hotspot. With the information collected so far (which needs confirmation) I realized that we will have to change the flow of the app:

• The application can make a request for a hotspot connection and receive its configurations (SSID and credentials)
• This hotspot is “dedicated” to this application, which means that in order to have a hotspot connection we have to share the configurations received with the user who wants to connect to the hotspot (requires changes in the UI).

In resume, the implemented solution is not the most elegant but the possible solution path does not allow to keep the existing behavior.
