    I would suggest that you search first, do what you can with what you find and then ask specific questions about what you don't understand.

    Maybe, but Xamarin with MySQL is rather specific, so there's no guarantee and, even if there is, what are the chances of the person who posted it seeing this thread and providing a link? Have you searched the CodeBank forum(s) to see whether you can find one?

    Based on what I can find, it seems that CRUD access to MySQL from Xamarin is not possible by default. It seems that you need to either purchase a commercial ADO.NET provider or create your own web service.

    Code:

                if (crud.delete(selectedItem))
                {
                    nameTxt.Text = "";
                    adapter = new ArrayAdapter(this, Android.Resource.Layout.SimpleListItem1, names);
                    lv.Adapter = adapter;
                }
            }
    
            void updateBtn_Click(object sender, EventArgs e)
            {
