我想虽然我的Andr​​oid应用程序在Facebook上分享的视频。

I want to share a video on Facebook though my Android app.

我贴在墙上，虽然我的应用程序，它的正常工作。现在，我想在Facebook上分享的视频。所以，我想下面code。

I posted a wall though my application, and it's working fine. Now I am trying to share a video on Facebook. So I tried below code.

    Facebook facebook;

    String FB_APP_ID=APP_ID;

    byte[] data = null;
    Uri uri=Uri.fromFile(new File(Environment.getExternalStorageDirectory(),"filename.mp4"));
    String dataPath = uri.getPath();
    String dataMsg = "Testing video sharing from my app";
    Bundle param;

    facebook = new Facebook(FB_APP_ID);
    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
    InputStream is = null;
    try {
        is = new FileInputStream(dataPath);
        data = readBytes(is);
        param = new Bundle();
        param.putString("message", dataMsg);
        param.putByteArray("video", data);
        mAsyncRunner.request("me/videos", param, "POST", new SampleUploadListener(), null);
    }
    catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    catch (IOException e) {
        e.printStackTrace();
    }

读取字节方法

The reading bytes method is

public byte[] readBytes(InputStream inputStream) throws IOException {
    // this dynamically extends to take the bytes you read
    ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();

    // this is storage overwritten on each iteration with bytes
    int bufferSize = 1024;
    byte[] buffer = new byte[bufferSize];

    // we need to know how may bytes were read to write them to the byteBuffer
    int len = 0;
    while ((len = inputStream.read(buffer)) != -1) {
        byteBuffer.write(buffer, 0, len);
    }

    // and then we can return your byte array.
    return byteBuffer.toByteArray();
}

该SampleUploader类

The SampleUploader class is

public class SampleUploadListener extends BaseRequestListener {

    public void onComplete(final String response, final Object state) {
        try {
            // process the response here: (executed in background thread)
            Log.d("Facebook-Example", "Response: " + response.toString());
            JSONObject json = Util.parseJson(response);
            final String src = json.getString("src");

            // then post the processed result back to the UI thread
            // if we do not do this, an runtime exception will be generated
            // e.g. "CalledFromWrongThreadException: Only the original
            // thread that created a view hierarchy can touch its views."
            Example1.this.runOnUiThread(new Runnable() {
                public void run() {
                    mText.setText("Hello there, video has been uploaded at \n" + src);
                }
            });
        }
        catch (JSONException e) {
            Log.w("Facebook-Example", "JSON Error in response");
        }
        catch (FacebookError e) {
            Log.w("Facebook-Example", "Facebook Error: " + e.getMessage());
        }
    }
}

这是行不通的，而在它的logcat显示下面的警告。

It is not working, and in logcat it shows the below warnings.
