When removing batteries from the beacon device, the list doesnt get refreshed #8

Hi

I am using the sample here with the library, and i came across a situation where in, the beacon gets detected when the cell is put into it, but when removed, the list is not refreshed until i press the scan button. is there a way i could be able to track that a beacon device is no longer part of the list? Please assist?

i notice that onScanResult log also stops when the beacon is not detected,but i could not track the log anywhere in the code.

Thanks
