How do I make 2 applications use the same database? If you create the bank in one app the other does not access this bank, then how to make that second app access that same bank?

I do not know if I understood your question well, but if you created the bank on a smartphone, another would probably not have access. What you should do in this case is to create a web service with a cloud bank where apps regardless of what smartphone you are on, can access. You see? If you need to have databases on smartphones, make sure you need to sync with the bank in the cloud, via service (API, Web servisse, etc.).
