Android App not detecting Beacon

I have implemented the beacon functionality by following:
https://developer.estimote.com/proximity/android-tutorial/

However, besides the location service is “requirement fulfilled”, it is not detecting the Beacon when it is in the range.
The logcat message that I am getting:
