I think you are missing some logic operator between those two conditions. eg.:
cursor = db.rawQuery("SELECT * FROM videoplayer where " + KEY_TAG_ONE + " like '%"+ searchText +"%' OR " + KEY_TAG_TWO + " like '%"+ searchText +"%'", null);
Which should select records where KEY_TAG_ONE or KEY_TAG_TWO contains searchText
solved Like query for multiple condition check android
