Conflict with dependency 'com.google.code.findbugs:jsr305' when importing pubsub in Android gradle #1936

I have a bare empty Android project, I am following this guide for PubSub java client.
So basically:

compile group: 'com.google.cloud', name: 'google-cloud-pubsub', version: '0.11.0-alpha'

My gradle file is here.

The error I get is:

Error:Conflict with dependency 'com.google.code.findbugs:jsr305' in project ':app'. Resolved versions for app (3.0.0) and test app (2.0.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.

There are also 2 warnings:

Warning:WARNING: Dependency org.json:json:20151123 is ignored for release as it may be conflicting with the internal version provided by Android.

Warning:WARNING: Dependency org.apache.httpcomponents:httpclient:4.0.1 is ignored for release as it may be conflicting with the internal version provided by Android.

I think this is related to #1319 but I can't make those suggested solutions work out.

Any suggestions?
