Error: UnsupportedCharsetException when upload file with MultipartEntity entity

Question

I send the form to the server, the text from the field and file Edittext. I think I will send the wrong shape. This is a form of sending the browser:

I upload file with help 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;

    }

In log i see error:

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

The error in this line

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

Try change the parameter in FileBody constructor: FileBody(filePathstorage, ContentType.MULTIPART_FORM_DATA, filename);

See: https://hc.apache.org/httpcomponents-client-ga/httpmime/apidocs/org/apache/http/entity/mime/content/FileBody.html#constructor_summary

Error: IllegalStateException: Content has been consumed in line responseString = EntityUtils.toString(r_entity);

upward unkaind Over a year ago

in line responseString = EntityUtils.toString(r_entity);

That's because you are consuming the response twice. The StringBuilder 's' variable already have the result, so you can do: responseString = s.toString();

Seems filename in

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

line interpreted as charset. This is because You probably use old version of Apache HttpClient Mime API.

So try something like that:

FileBody bin = new FileBody(new File(filename));

FileBody bin = new FileBody(new File(filename)); E/RESULT_OTVET: Response from server: java.io.FileNotFoundException: /IMG_20161115_113532.jpg: open failed: ENOENT (No such file or directory)

Andrii Omelchenko Over a year ago

You should combine filePathstorage and filename to get filename with full path to it. Like new FileBody(new File(filePathstorage + "\" +filename));. And "отправка с пк,тест" and "name="gorodFF"" - это так мило )

@ Andriy Omelchenko you propose to do so FileBody body = new FileBody(filePathstorage, ContentType.MULTIPART_FORM_DATA, filename); but I've already done that, and indicated the error below

Andrii Omelchenko Over a year ago

I'm propose FileBody(new File(filePathstorage + "\" +filename)); - with 1 argument not FileBody(filePathstorage, ContentType.MULTIPART_FORM_DATA, filename); - with 3.

And You use old (probably 4.3 or lower) Apache HttpClient Mime API. Update it, or better get rid of it (see official documentation and this).
