At the end of the tutorial, we will show you how to connect to the sample database using the sqlite3 tool. Then, we will give you the links to download the sample database and its diagram. public DatabaseHelper(Context context) Ĭursor cursor = database.query(DatabaseHelper.Summary: in this tutorial, we first introduce you to an SQLite sample database. For that we’ll need to create a custom subclass of SQLiteOpenHelper implementing at least the following three methods.Ĭonstructor : This takes the Context (e.g., an Activity), the name of the database, an optional cursor factory (we’ll discuss this later), and an integer representing the version of the database schema you are using (typically starting from 1 and increment later).

SQLiteOpenHelper wraps up these logic to create and upgrade a database as per our specifications. We will have option to alter the database schema to match the needs of the rest of the app.

When the application is upgraded to a newer schema - Our database will still be on the old schema from the older edition of the app.So we will have to create the tables, indexes, starter data, and so on. When the application runs the first time - At this point, we do not yet have a database.SQLiteOpenHelper is designed to get rid of two very common problems.

Android SQLite SQLiteOpenHelperĪndroid has features available to handle changing database schemas, which mostly depend on using the SQLiteOpenHelper class.

This structure is referred to as a schema. We can create our own tables to hold the data accordingly. SQLite is a typical relational database, containing tables (which consists of rows and columns), indexes etc. Once a database is created successfully its located in data/data//databases/ accessible from Android Device Monitor. Android SQLite native API is not JDBC, as JDBC might be too much overhead for a memory-limited smartphone. For Android, SQLite is “baked into” the Android runtime, so every Android application can create its own SQLite databases. Android SQLite combines a clean SQL interface with a very small memory footprint and decent speed. Android SQLiteĪndroid SQLite is a very lightweight database which comes with Android OS. Below is the final app we will create today using Android SQLite database. For many applications, SQLite is the apps backbone whether it’s used directly or via some third-party wrapper.
