android.database.sqlite.SQLiteException: no such table: tblUserResponse

I am new to SqlLite Database. I have created Database using SqlLite Database Browser and saved it in Android App Project Folder in path src/com/example/hello/databases/

I have also created tables already. Now, When I am trying to run code, It is showing error no such table found.
My code is as below :

public class DatabaseHandler extends SQLiteOpenHelper {

    private static final int DATABASE_VERSION = 3;
    private static final String DATABASE_NAME = "db_admin";

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

    @Override
    public void onCreate(SQLiteDatabase db) {

    }

    // Upgrading database
    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    }

    // Adding User Response When He/She attempts Questions...
    void addUserResponse(UserResponse response) {
        SQLiteDatabase db = this.getWritableDatabase();

        ContentValues values = new ContentValues();
        values.put("QId", response.getQId());
        values.put("OptionId", response.getOptionId());
        values.put("Responsedate", response.getResponseDate());

        // Inserting Row
        db.insert("tblUserResponse", null, values);
        db.close();
    }
}

Inserting values as :

        DatabaseHandler db = new DatabaseHandler(this);

        db.addUserResponse(new UserResponse("1", "1", "hello"));
        db.addUserResponse(new UserResponse("2", "1", "hello"));
        db.addUserResponse(new UserResponse("3", "3", "hello"));
        db.addUserResponse(new UserResponse("4", "2", "hello"));
