为什么我无法读取帐户信息？

Question

I am totally new in Web API's and am trying to build an Android application for watching google contacts. I'm stuck on a first step with OAuth. I'm done with sign in button and authorization. Button works correct and I can sign in my Google account, but when I'm trying to get something from this account logcat printing this massage "I/system_server: oneway function results will be dropped but finished with status OK and parcel size". Why is this happen? Becouse auth token is no longer valid? How to restore permission? How should I get information from account?

This is code:

        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestServerAuthCode(clientID).requestEmail().requestScopes
                (new Scope("https://www.googleapis.com/auth/contacts "))
                .build();

        mSignInClient = GoogleSignIn.getClient(this, gso);

        signInButton = findViewById(R.id.sign_in_button);
        getInfoButton = findViewById(R.id.getInfo);
        signInButton.setSize(SignInButton.SIZE_STANDARD);

        signInButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                switch (v.getId()){
                    case R.id.sign_in_button:
                        signIn();
                        break;
                }
            }
        });

    private void signIn(){
        Intent intent = mSignInClient.getSignInIntent();
        startActivityForResult(intent, RC_SIGN_IN);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RC_SIGN_IN) {
            Task<GoogleSignInAccount> task =
                    GoogleSignIn.getSignedInAccountFromIntent(data);
            if (task.isSuccessful()) {
                GoogleSignInAccount acct = task.getResult();
                account = acct;
                handleSignInResult(task);
            } else {
            }
        }
    }

And this how i trying to get info from account:

    private void getAccountInfo(){
        GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(this);
        if (acct != null) {
            String personName = acct.getDisplayName();
            String personGivenName = acct.getGivenName();
            String personFamilyName = acct.getFamilyName();
            String personEmail = acct.getEmail();
            String personId = acct.getId();
            Uri personPhoto = acct.getPhotoUrl();
            Log.d(TAG, acct.getDisplayName());
            Log.d(TAG, personGivenName);
            Log.d(TAG, personFamilyName);
        }
    }

And what about AccountManager? Should I use it? I would be glad to receive any information.
