I am new to android programing and I have two, one problem in the AsyncTask class named RetrieveTokenTask(), in this class I get a token for access email account on gmail, when I call the AsyncTask class create a infinite loop and the message for approbation is open and closed for the app.
The other problem is when I press the button revoke access for data, when try again login in the app not show the Layout with contains data.
I've done this following some tutorials.
Any help would helpful.
Thanks and sorry for any error in my writing but my english is not good.
This code for mi app is the next:
`protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
` ...

.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).addApi(Plus.API)
.addScope(Plus.SCOPE_PLUS_LOGIN).build();
}

super.onStart();
mGoogleApiClient.connect();
}

super.onStop();
if(mGoogleApiClient.isConnected()){
mGoogleApiClient.disconnect();
}
}
