Android App that adds, deletes, updates data with SQLiteOpenHelper Database

Android App - Add, delete, update data with SQLiteOpenHelper Database

I will assume that you already know how to open Android Studio and how to create a project with an Empty Activity in it. First, the Main Activity will be your Dashboard. Here we will list the data inserted in the database. You will need to create two List Views for that. In every Activity you create add the three buttons at the top. Those will be used to open a curtain Activity. Let’s start.

MainActivity.java and activity_main.xml

Database.java

Invocie.java and activity_invoice.xml

Client.java and activity_client.xml

AndroidManifest.xml

colors.xml

strings.xml

styles.xml
