My code in HotOrNot as follows

private static final int DATABASE_VERSION = 1;

private DbHelper ourHelper;

private static class DbHelper extends SQLiteOpenHelper {

}

public HotOrNot(Context c) {

}

public HotOrNot open() throws SQLException {
ourHelper = new DbHelper(ourContext);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}

public void close() {
ourHelper.close();
}

public long createEntry(String name, String hotness) {

}

public String getData() {
// TODO Auto-generated method stub

String[] columns = new String[] { KEY_ROWID, KEY_NAME, KEY_HOTNESS };
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null,
