I'm trying to make a Facebook login to my application using Parse core. I have followed tutorials on the following pages:
<https://parse.com/docs/android/guide#users-facebook-users>
<https://developers.facebook.com/docs/android/getting-started>

My app is initialized with Parse, Facebook SDK and ParseFacebookUtils. Though everything is OK till the moment my application gets to the LogInCallback() method. It always logs me 

```
"Uh oh. The user cancelled the Facebook login." 

```

with a ParseException messages of

```
"The supplied Facebook session token is expired or invalid."

```

The solution of embedding the Facebook app's App Secret didn't work for me.

```
ParseFacebookUtils.logInWithReadPermissionsInBackground(this, permissions, new LogInCallback() {
  @Override
  public void done(ParseUser user, ParseException err) {
    if (user == null) {
      Log.d("MyApp", "Uh oh. The user cancelled the Facebook login.");
    } else if (user.isNew()) {
      Log.d("MyApp", "User signed up and logged in through Facebook!");
    } else {
      Log.d("MyApp", "User logged in through Facebook!");
    }
  }
});

```

Can anybody help me?
