Introduction

In this step-by-step guide you can build a budget app. You will be using code from the previous tutorials (B4A-lists and B4A-calendar). A database class will be set up to use SQL queries to add, change or remove records from database tables. You will also learn how to use 'prepared statements' to prevent SQL-injection. The app uses dialog views for the database changes and for the selection of a date. Happy coding!
