Android FB Connect

I am trying to integrate the official FB SDK for android. below is the basic code

public class FbTestActivity extends Activity {
    Facebook facebook = new Facebook("112374492201730");

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        facebook.authorize(this, new String[] { "email", "read_stream" },

        new DialogListener() {

            public void onComplete(Bundle values) {
            }

            public void onFacebookError(FacebookError error) {
            }

            public void onError(DialogError e) {
            }

            public void onCancel() {

            }
        });
    }

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

        facebook.authorizeCallback(requestCode, resultCode, data);
    }
}

When i open the app the Log开发者_StackOverflow社区in or (if looged in) Permission dialog never shows up. Some dialog opens for a few mili secs and closes down.

The problem is the SSO (Single Sign On) feature of the login.

Following link will help you.

facebook login dialog disappears soon after loading
