The Google sign in option is a newer one on the site. It doesn't appear to have made it to the app yet.
Login with Google on Android app

yeah - it probably should have come with a warning - don't use if you want to also use this account on the android app... Anyone know of a workaround yet?

Until they add that option to the app, you'll either have to use the website or open a ticket with the site to have a regular password attached to your account. If you do that though, you might not be able to logon with the Google anymore; just depends on how they hook into that I guess.

Had the same problem, to get around this:
1. Do a password reset when not logged in from the website
2. Reset the password
3. Use the new password with your username in the android app

Its unimaginably stupid to allow a Google account login but then not allow that feature on Android the temple of all things Google!! But at the same time give the Google login option to Apple users on iphone and ipad.. I am in knots..

I just updated my Android app and the option to sign in with Google is there. I'm in the beta for the app so it should make it to the general release soon.
When I signed up online, I used 'Login with Google account', works great for web. I downloaded the android app, but only see 'Login with Facebook', or user/password. My google creds don't work for the password, so how do I login with the android app? I looked for a place to also connect my Facebook account, but didn't see it either.
Great site, and the app looks great, just can't seem to get logged in.
