Efiicient way to show 'Cant access network' View with 'Retry' and additional options like 'Wifi Settings', 'Mobile Network'

Question

I need to include this in my app

When should it get triggered?

• Any action triggered by user from UI requires internet

Answer 1

Volley DETROYS all listeners as soon as it receives something from the server, regardless of whether the response is a proper response or an error response.

A request needs to constructed everytime it should be sent or resent.

These steps will help achieve it

• Create a fragment with Retry and other necessary buttons like Wifi Settings, Mobile Network Settings
• Create a full sized FrameLayout inside RelativeLayout on necessary views to accommodate the fragment created and hide it initially
• When request fails, make the FrameLayout visible and the retry button should call the function that constructs and calls the request
