I've got an issue facing this Trailhead: instructions refer to Cordova version 6.4.0, but using this version I got an error creating the app with command "forcedroid create" :Installed Cordova version (6.4.0) is less than the minimum required version (7.0.0).
But if I upgrade Cordova to 7.0.0 version, it is not able to retrieve templates from GItHub and the app creation fails again.
Is there a way to get out of this? 
thanks

I'm not able to pass trailhead challenge for 'Get Started with Native Android Development' though I created and successfully logged in the app on my device. 
Also my login from the mobile device is tracked into the login history.
Don't know how to pass this challenge :(
Help!

I'm pretty sure I have created a hybrid mobile app - but I still get this message 'Challenge Not yet complete... here's what's wrong: You haven't run and logged in from the 'TrailheadHybridTest' app.' I created a new Dev org and logged in to the app OK but Trailhead won't let me pass this challenge.
