google oAuth for testing application
<p>I just started studying android development few days ago.. so totally new.
I wanted to test the google API, specifically this project:
<a href="https://github.com/googlesamples/android-fit/tree/master/BasicRecordingApi" rel="nofollow">https://github.com/googlesamples/android-fit/tree/master/BasicRecordingApi</a></p>

<p>When I create the .apk and I try on my phone I get an error "Eception while connecting to Google Play services: null"</p>

<p>Through a search I found out that it can be because I didn't setup oAuth.</p>

<p><a href="https://developers.google.com/fit/android/get-api-key" rel="nofollow">https://developers.google.com/fit/android/get-api-key</a></p>

<p>I don't have a developer account.
Do I need to sign up to be able to test the API?
Do I need to perform steps as it was my application that I am developing, also if I am just testing their app?</p>

<p>Thank you and sorry for the basic question..</p>
