路标回调适用于使用API​​ 10的Android Emulator，但不适用于API 15或16

Question

我相信我已经正确编码并设置了对Twitter的Signpost调用。在API 10（通过仿真器和实际手机）上运行时，它完全正常工作。但是当我在API 15或16上尝试完全相同的apk时，回调根本不起作用。它不是将我返回到我的应用程序，而是将其发送到另一个页面，该页面显示该页面不可用并标识我的回调URL + oauth令牌。我有

• 为活动设置android：launchMode =“singleInstance”
• 设置android：scheme和android：host以匹配传递给retrieveRequestToken
的回调URL

• 重写onNewIntent

  <activity
      android:name=".TimelineActivity"
      android:label="@string/app_name"
      android:launchMode="singleInstance">
      <intent-filter>
          <action android:name="android.intent.action.MAIN" />
          <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
  
      <!-- Used for OAuth callback -->
      <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:scheme="x-AbcdEfg41-oauth-twitter"
              android:host="callback" />
      </intent-filter>
  </activity>
  

onNewIntent看起来像这样：

    super.onNewIntent(intent);
    Log.d(TAG, "intent:  " + intent);

    //check if this is a callback from OAuth
    Uri uri = intent.getData();
    if (uri != null && uri.getScheme().equals(OAUTH_CALLBACK_SCHEME)) {
        Log.d(TAG, "callback:  " + uri.getPath());
        String verifier = uri.getQueryParameter(OAuth.OAUTH_VERIFIER);
        Log.d(TAG, "verifier:  " + verifier);

        new RetrieveAccessTokenTask().execute(verifier);
    }

我的auth电话看起来像这样：

try {
      authUrl = this.mProvider.retrieveRequestToken(this.mConsumer, OAUTH_CALLBACK_URL);
      Log.d(TAG, authUrl);
      Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl));
      intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
      startActivity(intent);
    }

我的logcat看起来还不错，虽然我对“没有检测到GPU仿真的仿真器”有点怀疑，因为我在API 10上运行时没有看到它：
