我试图从Android Uri到字节数组.

我有以下代码,但它一直告诉我字节数组长61个字节,即使文件非常大 - 所以我认为它可能将Uri 字符串转换为字节数组,而不是文件:(

  Log.d(LOG_TAG, "fileUriString = " + fileUriString);
  Uri tempuri = Uri.parse(fileUriString);
  InputStream is = cR.openInputStream(tempuri);
  String str=is.toString();
  byte[] b3=str.getBytes();
  Log.d(LOG_TAG, "len of data is " + imageByteArray.length
     + " bytes");

请有人帮我弄清楚该怎么办？

输出为"fileUriString = content:// media/external/video/media/53","len of data为61字节".

谢谢!

问题:

我的视频没有上传到Facebook.

问题:

如何将视频上传到Facebook？

注意:

我可以从我的画廊上传一张照片.

没有Exceptions被抛出.我认为这个问题存在问题

params.putString("filename", <selectedviedoPath> )

AsyncFacebookRunner mAsyncFbRunner = new AsyncFacebookRunner(mFacebook);
        Bundle params = new Bundle();
        //convert to byte stream
   **FileInputStream is = new FileInputStream(new File(selectedviedoPath));**
   ByteArrayOutputStream bs = new ByteArrayOutputStream();
        int data = 0;
        while((data = is.read()) != -1)
        bs.write(data);

        is.close();
        byte[] raw = bs.toByteArray();
        bs.close();

        params.putByteArray("video", raw);
        params.putString("filename", <selectedviedoPath> );
        mAsyncFbRunner.request("me/videos", params, "POST", new WallPostListener());

我正在尝试使用以下代码将视频上传到Facebook

public void uploadVideosFacebook(String videoPath)
{
    byte[] data = null;

    String dataMsg = "Your video description here.";
    String dataName="Mobile.wmv";
    Bundle param;

    AsyncFacebookRunner mAsyncRunner = new   AsyncFacebookRunner(API);
    InputStream is = null;
    try {
       is = new FileInputStream(videoPath);
       data = readBytes(is); 

       param = new Bundle();
       param.putString("message", dataMsg);
       param.putString("filename", dataName);
       param.putByteArray("video", data);
       mAsyncRunner.request("me/videos", param, "POST", new fbRequestListener(), null);



    } catch (FileNotFoundException e) {
       e.printStackTrace();
    } catch (IOException e) {
       e.printStackTrace();
    }
}



public byte[] readBytes(InputStream inputStream) throws IOException {
      // this dynamically extends …

是否可以使用Facebook SDK将视频从SD卡上传到Facebook？

我想通过我的Android应用在Facebook上分享视频.

我通过我的应用程序发布了一个墙,它工作正常.现在我想在Facebook上分享一个视频.所以我尝试下面的代码.

    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();
    } …
