我上传文件与帮助AsyncTask。

 private String uploadFile() {
        String responseString = null;
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(UPLOAD_URL);
        MultipartEntity entity = new MultipartEntity(
                HttpMultipartMode.BROWSER_COMPATIBLE);
        try {

            File filePathstorage = new File(getPath(filePath));//путь к файлу
            filename = filePathstorage.getName();//имя файла
            File path = Environment.getExternalStoragePublicDirectory(
                    Environment.DIRECTORY_PICTURES);
            //File sendingFile = new File(path, filename);
            FileBody body = new FileBody(filePathstorage, "Content-Type: image/jpeg", filename);
            entity.addPart(KEY_NAME, new StringBody(name));
            entity.addPart(KEY_NASELPUNKT, new StringBody(naselpunkt));
            entity.addPart(KEY_STREET, new StringBody(street));
            entity.addPart(KEY_DOM, new StringBody(house));
            entity.addPart(KEY_EMAIL, new StringBody(e_mail));
            entity.addPart(KEY_MESAGES, new StringBody(message));

            entity.addPart(KEY_IMAGE, body);//  public static final String KEY_IMAGE = "fileFF[]";

            Log.e("RESULT_OTVET_entity", "Response from server: " + entity);
            httppost.setEntity(entity);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity r_entity = response.getEntity();
            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);
            }
            Log.v("Response for POst", s.toString());

            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode == 200) {
                // Server response
                responseString = EntityUtils.toString(r_entity);
            } else {
                URLDecoder.decode(URLEncoder.encode(responseString, "iso8859-1"), "UTF-8");
                responseString = "Error occurred! Http Status Code: " + statusCode;
            }
        } catch (IOException e) {
            responseString = e.toString();
        }
        return responseString;
    }

在日志中看到错误:

Caused by: java.nio.charset.UnsupportedCharsetException: IMG_20161115_113532.jpg

这一行的错误

 FileBody body = new FileBody(filePathstorage, "Content-Type: image/jpeg", filename);
