How to add initial data to SQLite database?

Question

I need to add initial values to SQLite database, once application is started first time. How should I do it?

Answer 1

You should use SQLiteOpenHelper for this

    private static class OpenHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "rss.sqlite";
    private static final int DATABASE_VERSION = 1;

    OpenHelper(Context context) {
       super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }
    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("CREATE TABLE RSS (TITLE TEXT, LINK TEXT, DESCR TEXT, PUBDATE DATE, GUID TEXT, READ TEXT, TYPE TEXT)");
        db.execSQL("CREATE TABLE PAGE (LINK TEXT, CONTENT TEXT)");
    }

    @Override
    public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {

    }
}

And use it in code

    OpenHelper openHelper = new OpenHelper(this.context);
    this.db = openHelper.getWritableDatabase();
