Google API credentials not working as expected

Question

I am trying to get GoogleCredential for my project like given below,

GoogleCredential credential = new GoogleCredential.Builder()
                     .setTransport(httpTransport)
                     .setJsonFactory(jsonFactory)
                     .setServiceAccountId("xxx@famous-store-115417.iam.gserviceaccount.com")
                     .setServiceAccountScopes(SCOPES)
                     .setServiceAccountPrivateKeyFromP12File(new File(p12))
                     .build();

but I am getting below error,

I know it's permission related error, but I am using right key and service account id, and I have also searched it through web but it is the same solution suggested. I have refereed this as well.

Any suggestions are appreciated, thanks in advance. What should I am missing?

Finally I found the solution is,

I was using Goodle Drive API, so I need to share that document with service account (xxx@famous-store-115417.iam.gserviceaccount.com) as well. And after that it was working properly.

I hope it helps to someone else.

Did you not have to setServiceAccountUser ?? it would still work without it? – Sardonic Jul 06 '16 at 21:56
my code throws "Not Authorized to access this resource/api" error without `.setServiceAccountUser("admin@domain.com")` and without it, it would throw invalid_grant error.... – Sardonic Jul 06 '16 at 22:03
