How to find entry and exit events?

Question

I created an android android application to detect iBeacon and Eddystone. I tried to receive entry and exit events. I created two hashmaps with mac address as key and current time as value. Then I used a comparator to compare both hashmap objects. If the key is already present, I noted that the beacon is the last beacon. It does not fire any entry and exit events. Is there any other logic that will allow me to find the entry and exit event?

Answer 1

You have 2 types of input events:

[KeyboardView.OnKeyboardActionListener][1]
[Touch Events][2]
