Problem with Google Fit API on Android Wear

Question

I am trying to embed the Google Fit APIs in my Android app. I followed the online steps of GoogleFitAPI with registration for OAuth ID.

When I try to connect, I get an invalid account error.

Do I need to include a free trial in the api developer console or is there another problem that causes this?

mClient = new GoogleApiClient.Builder(this)
            .addApi(Fitness.API)
            .addScope(Fitness.SCOPE_ACTIVITY_READ)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
