安卓：在上傳視頻

Question

我想上傳到使用POST方法服務器的視頻，但我正在逐漸

FileNotFoundException異常

這裏是我的代碼文件中未發現異常。在PATH變量中我得到「內容：/媒體/外部/視頻/媒體/ 2」

public class VideoPlayUploadActivity extends Activity { 
private VideoView video_play; 
private Button accept_and_go; 
private Button reject_and_do; 
Uri vid; 
String user; 
String question; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.video_view); 

    video_play = (VideoView) findViewById(R.id.videoView1); 
    accept_and_go = (Button) findViewById(R.id.button_accept_and_go_over_video); 
    reject_and_do = (Button) findViewById(R.id.button_reject_and_do_over_video); 

    Intent extras = getIntent(); 
    vid = Uri.parse(extras.getStringExtra("uri")); 

    if (vid == null) { 
     Toast.makeText(VideoPlayUploadActivity.this, "No Video", 
       Toast.LENGTH_LONG).show(); 
    } else { 
     Toast.makeText(VideoPlayUploadActivity.this, 
       "Playback: " + vid.getPath(), Toast.LENGTH_LONG).show(); 
     MediaController mc = new MediaController(this); 
     getWindow().setFormat(PixelFormat.TRANSLUCENT); 
     video_play.setMediaController(mc); 
     video_play.setVideoURI(vid); 
     video_play.start(); 

    } 
    accept_and_go.setOnClickListener(accept_go_listener); 
} 

private View.OnClickListener accept_go_listener = new View.OnClickListener() { 

    @Override 
    public void onClick(View v) { 

     // TODO Auto-generated method stub 
     String path = vid.getPath(); 
     File file = new File(path); 
     try { 
      HttpClient client = new DefaultHttpClient(); 
      String postURL = "xxxxxxxxxxxxxxxxxxxxxxxxupdateAnswerFile"; 
      HttpPost post = new HttpPost(postURL); 
      FileBody bin = new FileBody(file); 
      StringBody user = new StringBody("1"); 
      StringBody question = new StringBody("25"); 
      MultipartEntity reqEntity = new MultipartEntity(
        HttpMultipartMode.BROWSER_COMPATIBLE); 
      reqEntity.addPart("user", user); 
      reqEntity.addPart("question", question); 
      reqEntity.addPart("answer", bin); 
      post.setEntity(reqEntity); 
      HttpResponse response = client.execute(post); 
      HttpEntity resEntity = response.getEntity(); 
      if (resEntity != null) { 
       Log.i("RESPONSE", EntityUtils.toString(resEntity)); 
      } 
     } catch (Exception e) { 
      Toast.makeText(getApplicationContext(), "exception", 0).show(); 
      e.printStackTrace(); 
     } 
    } 
}; 
private View.OnClickListener reject_do_listenter = new View.OnClickListener() { 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 

    } 
}; 
} 

請告訴我在哪裏，我錯了。

請按照下面的鏈接

Get filename and path from URI from mediastore

它的顯示，因爲你沒有內容路徑轉換成實際路徑錯誤。

它適用於我。

希望它有幫助。
