Hello, Database
To demonstrate SQLite, let’s create a little application called Events that stores records in a database and displays them later. We’re going to start simple and build up from there. Open a new “Hello, Android” program using these values in the project wizard:
| | Application name: Events |
| | Company Domain: example.org |
| | Form factors: Phone and Tablet |
| | Minimum SDK: API 16: Android 4.1 (Jelly Bean) |
| | Add activity: Blank Activity |
| | Activity Name: MainActivity |
| | Layout Name: activity_main |
| | Title: Events |
As always, you can download the complete source code from the book’s website[81] (look for the eventsv1 example).
We need somewhere to hold a few constants describing the database, so let’s create a Constants interface:
| eventsv1/src/main/java/org/example/events/Constants.java ... |
