Twitter身份驗證瀏覽器不回到我的Android應用程序

Question

我想弄清楚我的Android應用程序的Twitter OAuth。我的問題是，當Twitter OAuth瀏覽器打開，我點擊Authorize App按鈕，但它指向我的回調URL，在那裏暫停，並不會回到我的應用程序，隨後不會調用onNewIntent/onResume方法（我試過既使用這兩種方法，也不調用）。下面是我的活動代碼和清單XML文件。真的很感謝任何幫助或暗示。謝謝。

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"; 

private OAuthSignpostClient oauthClient; 
private OAuthConsumer mConsumer; 
private OAuthProvider mProvider; 
private Twitter twitter; 
private SharedPreferences prefs; 
private String authUrl; 
private WebView view; 
private Boolean status; 

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    try { 
     mConsumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, 
       CONSUMER_SECRET); 

     mProvider = new DefaultOAuthProvider(
       "http://api.twitter.com/oauth/request_token", 
       "http://api.twitter.com/oauth/access_token", 
       "http://api.twitter.com/oauth/authorize"); 

     prefs = PreferenceManager.getDefaultSharedPreferences(this); 
     String token = prefs.getString("token", null); 
     String tokenSecret = prefs.getString("tokenSecret", null); 

     if (token != null && tokenSecret != null) { 
      mConsumer.setTokenWithSecret(token, tokenSecret); 
      oauthClient = new OAuthSignpostClient(CONSUMER_KEY, 
        CONSUMER_SECRET, token, tokenSecret); 
     } else {

      new OauthAuthorizedTask().execute();

      // Store token in prefs 
      prefs.edit().putString("token", token) 
        .putString("tokenSecret", tokenSecret).commit(); 

      // Make a Twitter object 
      oauthClient = new OAuthSignpostClient(CONSUMER_KEY, 
        CONSUMER_SECRET, token, tokenSecret); 
      twitter = new Twitter(null, oauthClient); 

      Intent mainIntent = new Intent(TwitterLoginActivity.this, MainActivity.class);

        Toast.LENGTH_LONG).show(); 
     } 
    } 
} 

}

的Manifest.xml（注：已經設置使用許可權的android：NAME = 「android.permission.INTERNET對」）

<activity 
     android:name=".TwitterLoginActivity" 
     android:label="@string/twitter" 
     android:launchMode="singleTask" > 
     <intent-filter> 
      <action android:name="android.intent.action.VIEW" /> 
      <category android:name="android.intent.category.DEFAULT" /> 
      <category android:name="android.intent.category.BROWSABLE" /> 
      <data 
       android:host="mjelajah-prd.appspot.com/twitter/index" 
       android:scheme="http" > 
      </data> 
     </intent-filter> 
    </activity> 

Answer 1

與android:launchMode="singleInstance"嘗試。

private final String CALLBACKURL = "sosInternational:///Test"; 

<intent-filter> 
    <action android:name="android.intent.action.VIEW"></action> 
    <category android:name="android.intent.category.DEFAULT"></category> 
    <category android:name="android.intent.category.BROWSABLE"></category> 
    <data android:scheme="sosInternational" android:host="TwitterLoginActivity"></data> 
</intent-filter>
