從android設備上的Facebook牆上上傳視頻？

Question

我想從我的廚房到的Facebook牆上這裏上傳視頻是我的代碼

byte[] data = null; 
    String dataPath = "/mnt/sdcard/DCIM/Camera/video-2012-09-03-13-34-19.mp4"; 
    Bundle param; 
    //video extension 
    data Name = ".mp4" 
    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", "hello guys"); 
     param.putString("filename", data Name); 
     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 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(); 
} 

首先我得到這樣的警告日誌貓

W/Bundle ( 774): Attempt to cast generated internal exception: 
W/Bundle ( 774): java.lang.ClassCastException: java.lang.String 
W/Bundle ( 774): at android.os.Bundle.getByteArray(Bundle.java:1305) 
W/Bundle ( 774): at com.facebook.android.Util.openUrl(Util.java:172)

W/Bundle ( 774): at com.facebook.android.AsyncFacebookRunner$2.run(AsyncFacebookRunner.java:253) 
W/Bundle ( 774): Key format expected byte[] but value was a java.lang.String. The default value <null> was returned. 
W/Bundle ( 774): Attempt to cast generated internal exception:

W/Bundle ( 774): at com.facebook.android.Util.openUrl(Util.java:172) 
W/Bundle ( 774): at com.facebook.android.Facebook.request(Facebook.java:751) 

我在谷歌搜索一些人建議有錯誤在Facebook的API，他們建議我修改一些線在我Util.java

for (String key : parameters.keySet()) { 
      if (parameters.get(key) instanceof byte[]) { 

       continue; 
      } 

      sb.append("Content-Disposition: form-data; name=\"" + key 
        + "\"\r\n\r\n" + parameters.getString(key)); 
      sb.append("\r\n" + "--" + boundary + "\r\n"); 
     } 

     return sb.toString(); 
    } 

和

for (String key : params.keySet()) { 
       if (params.get(key) instanceof byte[]) { 
        dataparams.putByteArray(key, params.getByteArray(key)); 
       } 
      } 

現在我沒有得到任何警告任何錯誤，但我的影片不上傳，請幫助我，我在這裏打。

在此先感謝

Answer 1

我只是前幾天用這個stackoverflow post獲得視頻上傳到正常工作。我會重新開始，並按照該答案中的說明準確完成工作。我知道它的工作原理，因爲它只是在今天爲我工作。

試試這個，它適合我。

File file=new File("your video file name"); 
     try { 
      Request request = Request.newUploadVideoRequest(session, file, new Request.Callback() { 

       @Override 
       public void onCompleted(Response response) { 
        // TODO Auto-generated method stub 

        if(response.getError()==null) 
        { 
         Log.e("response",response.toString()); 
         Toast.makeText(MainActivity.this, "Video Shared Successfully", Toast.LENGTH_SHORT).show(); 
        } 
        else 
        { 
         Log.e("error",response.getError().getErrorMessage()); 
         Toast.makeText(MainActivity.this, response.getError().getErrorMessage(), Toast.LENGTH_SHORT).show(); 
        } 
       } 
      }); 

      request.executeAsync(); 
     } catch (Exception e) { 
      e.printStackTrace(); 

     }
