I'm trying to figure out Twitter OAuth for my Android application. My problem is when the Twitter OAuth browser opens, I click the Authorize App button but it directs to my callback URL, pauses there and doesn't go back to my app, subsequently not calling either of the onNewIntent/onResume methods (I have tried to use both of these two methods and neither are being called). My activity code and manifest XML file are below. Really appreciate for any help or hint. Thank you.
public class TwitterLoginActivity extends SherlockPreferenceActivity {
private static final String TAG = "TwitterDemo";
private static String CONSUMER_KEY = ""; // filled with my consumer key
private static String CONSUMER_SECRET = ""; //filled with my consumer secret
private static final String CALLBACK_SCHEME = "http";
private String CALLBACK_URL= CALLBACK_SCHEME+"://mjelajahprd.appspot.com/twitter/index";
