For now, Indoor Location SDK is available only for iOS mobile devices. Android version is definitely on our roadmap and we’ll proceed to develop it.
The main reason why it wasn’t developed simultaneously for both platforms is that every Android device is different and they use different Bluetooth antennas. Indoor Location is based on complex algorithms that take into account antenna's position, quality, orientation. There are also differences in Bluetooth support across devices and version of Android.
It takes a lot of time to develop such a complex tool like the Indoor Location SDK for hundreds of popular devices running Android. That is why at the beginning we focused on iOS environment but we still keep in mind that a lot of our developers want to try it out on others systems.
