Q:

Android Studio Mac new project errors after freshly created project

When I create  a new project on android studio, I get the error. " URI is not registered" on my  xmlns:android="http://schemas.android.com/apk/res/android" .  I go to my event log, click configure, and the error goes away, yet I get errors in the "android:icon, label and theme" values under application along with the "android:name and label" attributes under activity in the AndroidManifest.xml. 
Also, when trying to open my activity_main.xml layout files, I get the error
10:23:12 AM IllegalStateException: @NotNull method com/android/tools/idea/rendering/ManifestInfo.getActivityThemes must not return null

It works on the PC, but I am definitely missing something on the Mac.  Thanks for all of the help! 

A:

Update to version 3.0 Canary build on Mac.  Fixes all problems.
