In the "Develop with Mobile SDK" Trailhead, the module HTML and Hybrid, Getting Started with Development, I have completed all the instructions for both the iOS and android. I have also built the connected app, added my connected app session ID, and authentication key in my mobile app. The challenge gives an error "Challenge Not yet complete... here's what's wrong: 
You haven't run and logged in from the 'TrailheadHybridTest' app."

I am stuck at this part. 

Hi, I am trying to get the FirstReact project from Trailhead to work and I keep getting an error in Android Studio and the React-Native server when I click on the Run button in Android Studio.  Hoping that someone has run into this and can provide some insights.  I've been googling everywhere and tried a number of different things to resolve the error (delete the project and start over, gradelw clean, give all users full control over the folders, etc.) without any luck.  Any help would be greatly appreciated!!  Here's the kind of errors I am receiving:

In Android Studio:
Error:Could not read path 'C:\ReactNativeTests\FirstReact\mobile_sdk\salesforcemobilesdk-android\libs\SalesforceAnalytics\build\generated\source\r\debug\com\salesforce\androidsdk\analytics'.
> C:\ReactNativeTests\FirstReact\mobile_sdk\salesforcemobilesdk-android\libs\SalesforceAnalytics\build\generated\source\r\debug\com\salesforce\androidsdk\analytics

In the React Native server command window:
