Comment 1 John Miller [MSFT] 2017-07-07 16:39:50 UTC
I'm not able to reproduce this with the latest 15.3 preview build because I can't select 4.4.2 as an option. The lowest I can select is Android 5.0 and I have all the SDKs installed. I need confirmation of how to reproduce with 15.3 and/or if 4.4.2 is no longer supported in the designer (from engineering team).
Comment 2 Jon Douglas [MSFT] 2017-07-17 17:39:07 UTC
Marking duplicate as per description of not working in <= API 19
