"Calling this from your main thread can lead to deadlock and/or ANRs while getting accesToken" from GoogleAuthUtil(Google Plus integration in Android)

Question

In my android application, I am trying to get AccessToken from GoogleAuthUtil as below :

accessToken = GoogleAuthUtil.getToken(this, mPlusClient.getAccountName(), "oauth2:" + SCOPES);

But At this line I am gettting error as below :

E/GoogleAuthUtil(4696): Calling this from your main thread can lead to deadlock and/or ANRs E/GoogleAuthUtil(4696): java.lang.IllegalStateException: calling this from your main thread can lead to deadlock E/GoogleAuthUtil(4696): at com.google.android.gms.auth.GoogleAuthUtil.b(Unknown Source) E/GoogleAuthUtil(4696): at com.google.android.gms.auth.GoogleAuthUtil.getToken(Unknown Source) E/GoogleAuthUtil(4696): at com.google.android.gms.auth.GoogleAuthUtil.getToken(Unknown Source)

Any solution of this problem? Any help will be appreciated.

Hey @Ponting, this used to work for me, but only a few days ago it stopped working and now it throws this error com.google.android.gms.auth.GoogleAuthException: Unknown. Any idea why? Is there something wrong with my scopes? https://gist.github.com/lawloretienne/7351151 — Etienne Lawlor, Nov 07 '13 at 17:03

Try it with an AsyncTask like this:

        AsyncTask<Void, Void, String> task = new 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());
                    Intent recover = e.getIntent();
                    startActivityForResult(recover, REQUEST_CODE_TOKEN_AUTH);
                } 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) {
                Log.i(TAG, "Access token retrieved:" + token);
            }

        };
        task.execute();

SCOPES is a space separated list of OAuth 2.0 scope strings. For example SCOPES could be defined as:

public static final String SCOPES = "https://www.googleapis.com/auth/plus.login "
    + "https://www.googleapis.com/auth/drive.file";

These represent the permissions that your app is requesting from the user. The scopes requested in this example are documented here:

if you dont need to access drive, you shuold remove 'https://developers.google.com/drive/android/files' from scopes — KAPLANDROID, Apr 10 '14 at 14:27
Is it also possible retrieve the access token expiration time using some Android Google API? Or only through a HTTPS request? — JP Ventura, Dec 04 '14 at 16:51

Use separate thread for your internet code. Error is telling that more time consuming process is running in the app and here that is internet. So use separate thread or Async task.

Check out this link NetworkOnMainThreadException

Hope it will help you.

E/GoogleAuthUtil(4696): java.lang.IllegalStateException: calling this from your main thread can lead to deadlock

Sounds like you need to do that on a separate thread, have you tried that?

Here you can find information about threads in Android.

I tried with to run above code under new thread : new Thread(new Runnable() { public void run() { } }.start(); ..But it gives error that GoogleAuthUtil.getToken can not run on runnable method. – Ponting Jul 09 '13 at 11:32

            Thread CrearEventoHilo = new Thread(){
                public void run(){
                    //do something that retrun "Calling this from your main thread can lead to deadlock"
                }
            };
            CrearEventoHilo.start();

CrearEventoHilo.interrupt();

public class Foo {
    MyThread mTh;
    void cantBeBothered() {
        mTh = new MyThread( /*...*/ );
        mTh.run();
        mTh.start();
    }
    void imFinishedNowWaitingForThread() {
        mTh.join();
    }
    void imOutKillingOffPendingThread()  {
        mTh.interrupt();
    }
//  .....
    private class MyThread extends Thread {
//      ...;
        MyThread( /*...*/) {
//          this... = ...;
        }
        public void run() {
            doSomething( /*this...*/ );
        }
    }
}

Your answer will be more valuable if you add an explanation on how it works. — András Aszódi, Mar 27 '17 at 11:41
