We don't have to get this removed. tvData displayes the addresses of the connected devices.
Kindly rollback the changes from lines 186 to 192.

@AsCress Other than the SensorActivity the changes I have made because I was unable to run the application without making those changes. But after testing I will rollback it.

@AsCress to resolve this issue as you have said, I need to make changes in the method "PopulateSensors" to handle the cases where both having same addresses.
should I ?

@samruddhi-Rahegaonkar The problem here is with the data structure that we are using to store the sensor addresses.
A Map in Java doesn't allow duplicate keys to be inserted. When we try to do that in lines 86 and 87 of SensorActivity.java, it overwrites the previous entries, and hence the previous two sensors (MLX90614 and TSL2561) actually never get inserted in the Map.
The idea here would be to migrate to a different data structure which would allow storage of duplicate entries, and then using that in PopulateSensors to display them.

@AsCress Instead of Map<Integer, String>, we can use a Map<Integer, List<String>> to associate multiple sensor names with the same address.

@samruddhi-Rahegaonkar Yep, that's one way. Go ahead and maybe try to implement whatever you find best in this PR.
