使用Android中的MultipartEntity上传3gpp音频文件

I wanted to upload a file from android device to a server using PHP post. Now I researched on the multipart entity uploading and fixed everything on my android device but it's still not working and I just don't know why since this is the first time I'd tried to do this for android. Now what I have is this method:

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();
        }
    }

and I use an onclick listener to call this method with this format

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

where record location is this : /mnt/sdcard/Echo/Recordings/Awesome4.3gpp

and the PHP upload code:

<?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!";
}

?>

I already tried the upload and it's working which is why I think the problem is in my android method. By the way here's the logcat:

Did I missed out something here? Also maybe someone can explain me on how does this entity.addPart() works since since I dont know what is the content body it talking about and what string should I specify.

    Taken from my comment:

    android.os.NetworkOnMainThreadException says that you're posting on UI thread. Call postFile() either from an AsynkTask either from a background thread.
