使用Android中的MultipartEntity上传3gpp音频文件

Question

我想使用PHP发布将android设备上的文件上传到服务器。现在我研究了多部分实体上传并修复了我的android设备上的所有内容，但它仍然无法工作，我只是不知道为什么，因为这是我第一次尝试为android执行此操作。现在我已经是这个方法：

public void postFile(String file_path, String url){ 
     File file = new File(file_path); 

     try { 
      System.out.println(file_path); 
      HttpClient client = new DefaultHttpClient(); 
      HttpPost post = new HttpPost(url); 


      FileBody bin = new FileBody(file); 
      MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE); 
      reqEntity.addPart("file", bin); /*I believe that the "file" is the name in php part*/ 
      post.setEntity(reqEntity); 
      HttpResponse response = client.execute(post); 
      HttpEntity resEntity = response.getEntity(); 
      if (resEntity != null) { 
       Log.i("RESPONSE", EntityUtils.toString(resEntity)); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

我用一个onclick监听器调用此方法与此格式

postFile(record_location, "http://10.146.179.86/File%20upload/test.php"); 

，其中记录的位置是这样的：/mnt/sdcard/Echo/Recordings/Awesome4.3gpp

和PHP上传代码：

<?php 

$target_path = "Stored File/"; 

$target_path = $target_path . basename($_FILES['file']['name']); 

if(move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) { 
echo "The file ". basename($_FILES['file']['name']). 
" has been uploaded"; 
} else{ 
echo "There was an error uploading the file, please try again!"; 
} 

?> 

我已经尝试上传，它的工作这就是为什么我认为问题出在我的android方法中。顺便说说这里的logcat：

我在这里错过了什么吗？ 另外也许有人可以解释我这个entity.addPart（）如何工作，因为我不知道什么是它说的内容正文，我应该指定什么字符串。

从我的评论摘自：

android.os.NetworkOnMainThreadException说，你张贴在UI线程。通过后台线程从AsynkTask调用postFile()。
