Insert & Select Arabic data Android SQLite

Question

I'm trying to create arabic database in android application and want to see how I can achieve that?

I know that I will have to do encoding and stuff. But I want to know if someone really tried to create non-english database and help me to do the best approach.

So for create SQLite best approach is use SQLiteOpenHelper and create your own class that extending from SQLiteOpenHelper, implements onCreate(), method and onUpgrade() method.

Example how to create database:

public class DatabaseHandler extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "basic_login_system_database";
    protected static final String USER_TABLE_NAME = "User";
    protected static final int DATABASE_VERSION = 1;

    protected static final String KEY_ID = "id";
    protected static final String KEY_NAME = "name";
    protected static final String KEY_SURNAME = "surname";
    protected static final String KEY_PASSWORD = "password";
    protected static final String KEY_EMAIL = "email";
    protected static final String KEY_ADDRESS = "adress";
    protected static final String KEY_AGE = "age";


    public DatabaseHandler(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }       

    public void onCreate(SQLiteDatabase db) {
        String CREATE_USER_TABLE = "CREATE TABLE " + USER_TABLE_NAME + "("
                + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
                + KEY_NAME + " TEXT NOT NULL, "
                + KEY_SURNAME + " TEXT NOT NULL, "
                + KEY_PASSWORD + " TEXT NOT NULL, "
                + KEY_EMAIL + " TEXT UNIQUE NOT NULL, "
                + KEY_ADDRESS + " TEXT, "
                + KEY_AGE + " TEXT" + ")";
        db.execSQL(CREATE_USER_TABLE);
    }

    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        String DELETE_USER_TABLE = "DROP TABLE IF EXISTS " + USER_TABLE_NAME;
        db.execSQL(DELETE_USER_TABLE);
        onCreate(db);       
    }
}

And you must set encoding for Arabic characters because implicitly is it set on utf-8.

private static final String ENCODING_SETTING = "PRAGMA encoding ='windows-1256'";

And you set it in your onOpen() method.

@Override
public void onOpen(SQLiteDatabase db) {
   if (!db.isReadOnly()) {
      db.execSQL(ENCODING_SETTING);
   }
} 

Then for retrieve data from your database just use Cursor with methods rawQuery() or query().

Example: Cursor c = db.raQuery(SELECT_STATEMENT, null);

For insert data use insert() method of SQLiteDatabase.
