How do I get access token using Google plus

Question

I have followed this tutorial in order to get the access token and it works as shown in the link. Now how do I get the email and profile pic from this? I have implemented found this tutorial which shows me how to quick start with google+ signin.

But in this how do I get the access token?

I have found these links which shows me the basic part but can anyone say me where do I need to implement them ?

So how do I use this using AsyncTask

Finally I would like to get the access token, email and profile pic and how from anyone of the tutorial?

Any suggestions are welcome.

Few ways. This is the easiest to understand. First, build a class extending AsyncTask<>. You want a String[] to be the return type. Note: AsyncTask<Params, Progress, Result> so if you want to return a string, you need to extend AsyncTask<Void, Void, String>

 public class YourAsyncTaskName extends AsyncTask<Void, Void, String> {
        @Override
        protected String doInBackground(Void... params) {
            String token = null;

            try {
                token = GoogleAuthUtil.getToken(
                        MainActivity.this,
                        mGoogleApiClient.getAccountName(),
                        "oauth2:" + SCOPES);
            } catch (IOException transientEx) {
                // Network or server error, try later
                Log.e(TAG, transientEx.toString());

            } catch (UserRecoverableAuthException e) {
                // Recover (with e.getIntent())
                Log.e(TAG, e.toString());  

            } catch (GoogleAuthException authEx) {
                // The call is not ever expected to succeed
                // assuming you have already verified that 
                // Google Play services is installed.
                Log.e(TAG, authEx.toString());
            }

            return token;
        }

        @Override
        protected void onPostExecute(String token) {
            /* here you have your token */
            Log.i(TAG, "Access token retrieved:" + token);
        }

 }

Then to start this task, just create an instance and call .execute();

YourAsyncTaskName asyncTask = new AsyncTaskName();
asyncTask.execute();
