Update to Android 11 (API Level 29)

[jpventura]

A long time has passed since this project was updated to the latest version of Android.

It would be nice to migrate it to the latest stable version of Android Jetpack.

This would indeed be great! Any chance you're interested in taking a crack at it? :)

@jamesagnew actually I was just opening the issue for the formality of associate it to a pull request.

The DSTU2 server seems to be down, so the test is failing. Someone need to start the Hapi FHIR container or give another url I could patch into PR #4.

Hi @jpventura , oops! Weird coincidence I just happened to check github right as you were submitting this!

The fhirtest.uhn.ca host is having issues right now, but it's just a mirror of the actual server:
http://hapi.fhir.org/baseDstu2/Patient/

That server is up.

Thank you @jamesagnew. Now the test is passing at Travis CI.
