Facebook的shareDialog是\未安装应用程序时 - 怪异的行为？

为了我的应用程序中共享在Facebook上PRINTSCREEN像我使用了Facebook的ShareDialog。Facebook的shareDialog是未安装应用程序时 - 怪异的行为？

当安装Facebook应用程序，它工作正常的。

当Facebook应用程序不安装，这是行不通的。我看到“加载”屏幕，然后消失，没有任何反应。份额对话对象达到的onError与FacebookException回调：

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

所以我真的只需要为Facebook网页而不是Facebook应用程序“publish_actions”权限？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."

我的代码：当Facebook应用程序是没有 “publish_actions” 安装不当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); 
    }

那么，为什么它的工作原理应用程序未安装？
