使用以下方法将音频文件上传到服务器。

你为什么不尝试这样，
try {
HttpClient httpClient = new DefaultHttpClient();
String url = "http://thinksl.com/taughtable/audiopost.php";
HttpPost httppost = new HttpPost(url);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("file", new FileBody(new File(path)));
reqEntity.addPart("filename", final_upload_filename);
httppost.setEntity(reqEntity);
HttpResponse response = httpClient.execute(httppost);
BufferedReader reader = new BufferedReader(new InputStreamReader(
response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
System.out.println("Response: " + s);
Log.e(TAG, "Response: " + s);
status = "" + s;
} catch (Exception e) {
e.printStackTrace();
}
