Android app compatible with API level 16 (Android 4.1)

Google's June 2015 Report on Android platform versions: 51,6% use Android version 4.4. and higher, but 37,4% use Android versions from 4.1. to 4.3. I guess it would make much more sense to enable the use of this app for 89% (51,6+37,4) of users instead of just 51,6% (as it is the case now because the Power BI Android app supports only version 4.4. and higher).
