Facebook login fails on some devices

Question

I have implemented the Facebook login and it works fine on some devices/AVDs. My development device is a Gingerbread phone, but testing it with a 4.1.1 device, it simply doe

Answer 1

Try inserting this line where you define your login button in the java source code

LoginButton fb_button = (LoginButton)findViewById(//your resource id);
fb_button.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);

Answer 2

List<String> permissions = new ArrayList<String>();
permissions.add("email");



//start Facebook session
openActiveSession(this, true, new Session.StatusCallback() {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        if (session.isOpened()) {
            //make request to the /me API

            Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
                @Override
                public void onCompleted(GraphUser user, Response response) {
                    if (user != null) {
                        String firstName = user.getFirstName();
                        String lastName = user.getLastName();
                        String id = user.getId();
                        String email=null;
                        try {
                            email = user.getProperty("email").toString();
                        } catch (Exception e) {
                            // TODO: handle exception
                        }

                        String gender = (String) user.getProperty("gender");
                        String birthday = user.getBirthday();



                    //welcome.setText("Hello \n" + firstName+"\n"+lastName+"\n"+email+"\n"+gender+"\n"+birthday+"!");




                    if(firstName!=null)
                    {


                          SharedPreferences.Editor editor = settings.edit();

                            editor.putString("fligin", "1");
                            editor.putString("firstName", firstName);
                            editor.putString("lastName", lastName);
                            editor.putString("email", email);
                            editor.putString("gender", gender);
                            editor.putString("birthday", birthday);
                            editor.commit();

                        Intent intent=new Intent(getApplicationContext(), RegistrationOneActivity.class);
                        startActivity(intent);
                        //overridePendingTransition( R.anim.slide_in_up, R.anim.slide_out_up );

                        finish();
                    }
                    else {

                        Toast.makeText(getApplicationContext(),"Person information is null", Toast.LENGTH_SHORT).show();

                    finish();
                        }



                    }
                }
            });
         }
     }
 }, permissions);

Other wise its very difficult to solve your problem here. So you can refer this link.

I hope you will success.

There is certainly a conflict between your stock app and the SDK. So if you don't want to uninnstall the stock HTC app and still use the SDK 3.0 I think your best bet without modying the source code of the sdk would be to disable SSO and login only through webview.

This can easily be done by adding the SessionLoginBehavior.SUPRESS_SSO everytime you try to open a new session. Here is a sample I changed from the SessionLoginSample (LoginUsingActivityActivity) from the Facebook SDK to show you what to do :

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    Session session = Session.getActiveSession();
    if (session == null) {
        if (savedInstanceState != null) {
            session = Session.restoreSession(this, null, statusCallback, savedInstanceState);
        }
        if (session == null) {
            session = new Session(this);
        }
        Session.setActiveSession(session);

        //add the check, for if session is opened
        if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED) || !session.getState().isOpened()) {
            //Add the suppress SSO behavior to force webview auth dialog to popup
            session.openForRead(new Session.OpenRequest(this).setCallback(statusCallback).setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO));
        }
    }
  ...
}
//then put your code in the statusCallback method or keep it in the session state change listener
