Facebook的shareDialog是\未安裝應用程序時 - 怪異的行爲？

爲了我的應用程序中共享在Facebook上PRINTSCREEN像我使用了Facebook的ShareDialog。Facebook的shareDialog是未安裝應用程序時 - 怪異的行爲？

當安裝Facebook應用程序，它工作正常的。

當Facebook應用程序不安裝，這是行不通的。我看到「加載」屏幕，然後消失，沒有任何反應。份額對話對象達到的onError與FacebookException回調：

{FacebookGraphResponseException: (#200) Requires extended permission: publish_actions httpResponseCode: 403, facebookErrorCode: 200, facebookErrorType: OAuthException, message: (#200) Requires extended permission: publish_actions}

所以我真的只需要爲Facebook網頁而不是Facebook應用程序「publish_actions」權限？奇怪..

Facebook writes:

https://developers.facebook.com/docs/sharing/android

"If the Facebook app is not installed it will automatically fallback to the web-based dialog" 

"Now the SDK automatically checks for the native Facebook app. If it isn't installed, the SDK switches people to their default browser and opens the Feed Dialog."

我的代碼：當Facebook應用程序是沒有「publish_actions」安裝不當Facebook工作

mShareDialog = new ShareDialog(mActivity); 

    mShareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() { 
     @Override 
     public void onSuccess(Sharer.Result result) {} 

     @Override 
     public void onCancel() {} 

     @Override 
     public void onError(FacebookException error) { 
      if (error != null) { 
       showDialog("facebook app isn't installed"); 
      } 
     } 
    }); 

    if (ShareDialog.canShow(ShareLinkContent.class)) { 

     // get a screenshot 
     Bitmap image = getScreenshot(); 

     SharePhoto photo = new SharePhoto.Builder() 
       .setBitmap(image) 
       .setCaption(getResources().getString(R.string.shareBodyText)) 
       .build(); 

     SharePhotoContent content = new SharePhotoContent.Builder() 
       .addPhoto(photo) 
       .build(); 

     mShareDialog.show(content); 
    }

那麼，爲什麼它的工作原理應用程序未安裝？
