Android - How can I share directions/route from Google Maps App?

I have not been able to find out how to do that either. However, I have found you can share places by clicking on them and then selecting "Share this place."

Unfortunately, there is no way to create these links in the Google Maps app.

As of the date of this posting you can not do this in the android app. HOWEVER you can access it through Google maps website. So instead of using your app navigate to Google maps through your browser. It will take a bit longer to load so only do this if you have to share the map or directions. Seems like a natural to be able to share this function via sms to non smart phones. It equals free advertising for Google. I hope they add this soon to the mobile app!
