使用GraphApi在Facebook上发布图像不起作用

Question

我想使用Graph API在Facebook上发布图像。我已经将图像转换为字节数组并尝试发布它，但是我失败了。它显示贴在墙上的文字，但图像不张贴。我不知道什么是错的。

我已经检查了以下可用的解决方案，但他们都没有为我工作。

1）How to post image from drawable folder to facebook with graph api?

2）Unable to post an image from drawable to facebook

3）Post image with text on facebook from android

4）Android photo upload to facebook using graph api?

这里是我试图的代码。

private void publishFeedDialog() { 
     Bitmap bitmap = BitmapFactory.decodeResource(this.getResources(), 
       R.drawable.ic_launcher); 

     ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
     bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream); 
     byte[] bitMapData = stream.toByteArray(); 

     final Bundle params = new Bundle(); 
     params.putString("name", "Test FB Post."); 
     params.putString("method", "photos.upload"); 
     params.putByteArray("picture", bitMapData); 

     //Tried below code but not working.   
     /*try { 
      String response = mFacebook.request("me/photos", params, "POST"); 
     } catch (FileNotFoundException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (MalformedURLException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     }*/ 
     WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(m_context, 
       Session.getActiveSession(), params)).setOnCompleteListener(
       new OnCompleteListener() { 

        @Override 
        public void onComplete(Bundle values, 
          FacebookException error) { 
         if (error == null) { 
          // When the story is posted, echo the success 
          // and the post Id. 
          final String postId = values.getString("post_id"); 
          if (postId != null) { 
           Toast.makeText(m_context, 
             "Posted story, id: " + postId, 
             Toast.LENGTH_SHORT).show(); 

           finish(); 
          } else { 
           // User clicked the Cancel button 
           Toast.makeText(m_context, "Publish cancelled", 
             Toast.LENGTH_SHORT).show(); 
          } 
         } else if (error instanceof FacebookOperationCanceledException) { 
          // User clicked the "x" button 
          Toast.makeText(m_context, "Publish cancelled", 
            Toast.LENGTH_SHORT).show(); 
         } else { 
          // Generic, ex: network error 
          Toast.makeText(getApplicationContext(), 
            "Error posting story", Toast.LENGTH_SHORT) 
            .show(); 
         } 
        } 

       }).build(); 
     feedDialog.show(); 
    } 

请指导我。任何帮助将不胜感激。

感谢

最后我解决我的问题，使用Simple Facebook SDK for Android which wraps original Facebook SDK 3.5

该SDK提供简单的方式来分享在Facebook上墙图像使用其中提到的SimpleFacebook类的资源在Facebook上共享图像。

您可以将照片发布（上传）到默认相册或任何其他相册中。

• 位图
• 文件
• 的byte []

private SimpleFacebook mSimpleFacebook; 
mSimpleFacebook = SimpleFacebook.getInstance(this); 
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), 
        R.drawable.ic_launcher); 
    // create Photo instace and add some properties 
Photo photo = new Photo(bitmap); 
photo.addDescription("Screenshot from sample application"); 
photo.addPlace("110619208966868"); 
// publish 
mSimpleFacebook.publish(photo, new OnPublishListener() 
{ 
    @Override 
    public void onFail(String reason) 
    { 
    mProgress.hide(); 
    // insure that you are logged in before publishing 
    Log.w(TAG, "Failed to publish"); 
    } 
    @Override 
    public void onException(Throwable throwable) 
    { 
      mProgress.hide(); 
     Log.e(TAG, "Bad thing happened", throwable); 
    } 
    @Override 
    public void onThinking() 
    { 
    // show progress bar or something to the user while publishing 
     mProgress = ProgressDialog.show(this, "Thinking", 
    "Waiting for Facebook", true); 
    } 
    @Override 
    public void onComplete(String id) 
    { 
     mProgress.hide(); 
     toast("Published successfully. The new image id = " + id); 
    } 
});
