Unable to access facebook login?

问题

I am using Facebook's official Android SDK, and I am administrator of an app on Facebook.

I read that by default, the app is in sandbox mode and no one except administrator and developers can access it. I am using it to add Facebook login facility in my android app. However, I added my friends, who are developing the app with me as developers, but they cant log in via Facebook with their account credentials from the app. I disabled the sandbox mode for app from Facebook's app settings, still they cant access the login facility. Once they click on Facebook login button, they are redirected to the same activity without anything happening, whereas in my case, I login successfully and the app proceeds normally.

Are there any extra settings I need to do in order to make it public?

Thanks :)

                                try {
                                    location = user.getLocation()
                                            .getProperty("name")

                                } catch (Exception e) {

                                    e.printStackTrace();
                                }



                            }

                            return;
                        }

                    });

                }
            }
        });

Put onActivityResult Method

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode,
            resultCode, data);
}

isSubsetoff() Method

   private boolean isSubsetOf(Collection<String> subset,
        Collection<String> superset) {
    for (String string : subset) {
        if (!superset.contains(string)) {
            return false;
        }
    }
    return true;
}

and the permissions as per your need

  private static final List<String> PERMISSIONS = Arrays.asList("email",
        "user_about_me", "user_location", "user_checkins");
