#Android sqlite database android#

Implementation of the AndroidX SQLite interfaces via the Android framework APIs. Implementation "androidx.sqlite:sqlite-ktx:$sqlite_version"

#Android sqlite database update#

We define a DBManager class to perform all database CRUD(Create, Read, Update and Delete) operations.Implementation "androidx.sqlite:sqlite:$sqlite_version"

Hence we can figure out the best way to convert the database from the old schema to the new one. onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) : It’s called when the schema version we need does not match the schema version of the database, It passes us a SQLiteDatabase object and the old and new version numbers.It passes us a SQLiteDatabase object, pointing to a newly-created database, that we can populate with tables and initial data. onCreate(SQLiteDatabase db) : It’s called when there is no database and the app needs one.Super(context, DB_NAME, null, DB_VERSION) Constructor : 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).For that we’ll need to create a custom subclass of SQLiteOpenHelper implementing at least the following three methods.

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.
