I was advised by the administrator to open another thread, providing more information about the issue. I’m using B4XPages (I'm migrating from activities to B4XPages) and I'm new to this approach. I'm trying to make it so that when the user hasn't logged in, the login screen is shown, and if they are already logged in, it goes directly to the app with the login data, without having to enter the credentials every time the app starts. My issue is that after 5 to 7 minutes in the background, the app asks for the login again. I was recommended to use KVS, and here is what I have and what it generates: I have this code in the B4XMainPage:
And in formprincipal_B4XPages, I have this code:
When we start for the first time, it achieves the objective and everything is displayed correctly, but when the app goes into the background and is restarted, on the line:
CLV1.Add(CreateItem(CLV1.AsView.Width, nombreComercio, bitmaps.Get(1), content,i,logo,url_store,telefono,estatusActual,isOpenToday,url_ubicacion), "")
It generates this error:
Please help me!!!!!
