callback not getting called properly in twitter Integration
===

I am using following Code.

    <activity android:name=".PrepareRequestTokenActivity" 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:scheme="http" android:host="m.devbee.com" />
    	</intent-filter>
     </activity>

My Twitter app Callback Url is `Callback URL 	http://m.devbee.com`


Now the problem is after this function is called

    @Override
    	protected Void doInBackground(Void... params) {
    		
    		try {
    			Log.i(TAG, "Retrieving request token from Google servers");
    			final String url = provider.retrieveRequestToken(consumer, Constants.OAUTH_CALLBACK_URL);
    			Log.i(TAG, "Popping a browser with the authorize URL : " + url);
    			Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url)).setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_FROM_BACKGROUND);
    			context.startActivity(intent);
    		} catch (Exception e) {
    			Log.e(TAG, "Error during OAUth retrieve request token", e);
    		}
    
    		return null;
    	}

I click on "Authorize App" Button in my browser and instead of it calling my `PrepareRequestTokenActivity` activity, it gives error saying

    Web Page Not avaliable.

Why the activity is not being called. The Urls are both same.
