query from id to id in SQLite

i wanna to get query from an id to an id so i used this code:

public List<Convers> getConversation(long min,long max){
    List<Convers> queryconvlist = new ArrayList<Convers>();
    Cursor querycursor = database.query(dbHelper.getTableName(1),null, DatabaseHandler.ConvID+" >= "+String.valueOf(min)+" AND " + " < "+String.valueOf(max), null, null, null, null);

    querycursor.moveToFirst();
    while (!querycursor.isAfterLast()) {
        Convers queryconversation = cursorToConv(querycursor);
        queryconvlist.add(queryconversation);       
        querycursor.moveToNext();
    }
    querycursor.close();        
    return queryconvlist;
}

but the app has crashed and logcat is
