I´m developing a app who can show the coordinates(latitude and longitude) and i want to store that coordinates in a databank(who can be tinywebdb or tinydb). But i can´t do it. Can anyone send the code/blocks for me? Or explain anything about it?

Lo que me ocurre es que he creado una aplicacion donde se abre una nueva pantalla y esta abre otra.
Cuando le pulso a mi boton de cerrar aplicacion siempre me vuelve a una de mis pantallas. Nunca cierra la aplicacion.
¿Alguna sugerencia o idea?
