Hi,
In Android 4.3, i understood as Android devices can't act as a Beacons because of not supporting for BLE Peripheral mode. But, Android L comes with supporting for BLE Peripheral Mode. So, Is it possible to the Android Devices now act as a Beacons?
Technically: yes, via the following class:

Practically: iBeacon is a closed, proprietary protocol, so you'd need to obtain its specification from Apple in order to know how to set up your BLE peripheral.
