In my DJI app I was using some of the widgets from these libraries, djiui.aar and djiui_native.jar. but even though the files are still in my extra libraries folder, they don't show up in my project libraries tab, or in the designer. Why is this?  I would like to keep using them. 
Here's the link about them:
