android Method for Getting ibeacon List

- OfStack
android Get the list of ibeacon for your reference. The details are as follows
Recently, the company needs to do ibeacon.
Because it involves the time of scanning code. Specially write an service implementation to obtain the list, which can scan out the ibeacon list according to the scanning time
Contains uuid, equipment name, unit (m), electricity quantity, etc.
Please modify the code according to your own project.
The core code is as follows:
