Question

I am trying to change my Facebook SDK from 3.20 to 4.x. The video upload gets broken with the new SDK.

Here is the code that is working in 3.20:

    Request request = Request.newUploadVideoRequest(session, new File(videoPath), callback);
    Bundle params = request.getParameters();
    params.putString("title", albumName);
    params.putString("description", " #SomeTag");
    request.setParameters(params);
    request.executeAsync();

Here are the different things I have tried with the new SDK 4.x. But every time I get the same error:

{FacebookServiceException: httpResponseCode: 500, facebookErrorCode: 6000, facebookErrorType: FacebookApiException, message: There was a problem uploading your video file. Please try again with another file.}

1.

    AccessToken accessToken = AccessToken.getCurrentAccessToken();
    GraphRequest request = GraphRequest.newPostRequest(accessToken, "me/videos", null, callback);
    Bundle params = request.getParameters();
    params.putString("file_url", videoPath);
    params.putString("title", albumName);
    File videoFile = new File(videoPath);
    ParcelFileDescriptor descriptor = ParcelFileDescriptor.open(videoFile, ParcelFileDescriptor.MODE_READ_ONLY);
    params.putParcelable("source", descriptor);
    params.putString("description", " #SomeTag");
    request.setParameters(params);
    request.executeAsync();

2.

    AccessToken accessToken = AccessToken.getCurrentAccessToken();
    GraphRequest request = GraphRequest.newPostRequest(accessToken, "me/videos", null, callback);
    Bundle params = request.getParameters();
    params.putString("file_url", videoPath);
    params.putString("title", albumName);
    byte[] byteVideo = getFileByteArray(videoPath);
    params.putByteArray("source", byteVideo);
    params.putString("description", " #SomeTag");
    request.setParameters(params);
    request.executeAsync();

3.

    AccessToken accessToken = AccessToken.getCurrentAccessToken();
    GraphRequest request = GraphRequest.newPostRequest(accessToken, "me/videos", null, callback);
    Bundle params = request.getParameters();
    params.putString("file_url", videoPath);
    params.putString("title", albumName);
    params.putString("source", "{video-data}");
    params.putString("description", " #SomeTag");
    request.setParameters(params);
    request.executeAsync();

I'd appreciate any help. I have not found any video upload sample from Facebook either for the new SDK.

花了1.5天后，我终于开始工作了。基本思想是将视频作为multipart / form-data发送，在这种情况下我使用的是byteArray。我从Bhavesh Hirpara给出的关于这个问题的答案中得到了这个想法： Is uploading videos from an SD Card to Facebook possible with the Facebook SDK?

还有几个警告，感觉更像Facebook Android SDK中的错误，但它们是：

不包括＆＃34;来源＆＃34;或＆＃34; file_url＆＃34;在请求参数中，即使FB文档说明了这一点。
在请求参数中包含针对某些字符串（例如视频文件名）的视频数据。

这是工作代码。

    AccessToken accessToken = AccessToken.getCurrentAccessToken();
    GraphRequest request = GraphRequest.newPostRequest(accessToken, "me/videos", null, callback);
    Bundle params = request.getParameters();
    try {
        byte[] data = readBytes(videoPath);
        params.putByteArray("video.mp4", data);
        params.putString("title", albumName);
        params.putString("description", " #SomeTag");
        request.setParameters(params);
        request.executeAsync();
    }
    catch (Exception e) {
        e.printStackTrace();
    }


    public byte[] readBytes(String dataPath) throws IOException {

        InputStream inputStream = new FileInputStream(dataPath);
        ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();

        byte[] buffer = new byte[1024];

        int len;
        while ((len = inputStream.read(buffer)) != -1) {
            byteBuffer.write(buffer, 0, len);
        }

        return byteBuffer.toByteArray();
    }

试试这个。 Uri videoFileUri = ... ShareVideo = new ShareVideo.Builder（） .setLocalUrl（videoUrl）。建立（）; ShareVideoContent content = new ShareVideoContent.Builder（） .setVideo（ShareVideo） .build（）;
