Developing the ProjectGurukul Expense Tracker app

Let’s look at the files that we created for the Expense Tracker app before we implement it. Let us see them one by one-

1. Activity_dashboard.xml is the file that will contain all the design codes of our dashboard activity.
2. The next file is the dashboard.java activity where we will be writing all the logic of our application.
3. The next file is income.xml and expense.xml which will contain all the design codes of our income and expense activity.
4. The next file is income.java and expense.java which we will be writing all the logic of our application.
5. We will also create a databaseHandler.java which will handle all the database activities.
