How to upload audio to soundcloud via my android app using retrofit 2

I'm trying to upload my .mp3 file to soundcloud using this retrofit2 interface :

public interface ApiInterface {
@Multipart
@POST("tracks?client_id=********&client_secret=********")
Call<ResponseBody> uploadTrack(@Part("track") RequestBody file, @Part("track[title]") String title, @Part("track[sharing]") String sharing);
}

and realization with interceptor to include token:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    initComponents();

    sharedPreferences = getSharedPreferences(getApplicationInfo().name, MODE_PRIVATE);
    token = sharedPreferences.getString(Config.ACCESS_TOKEN, "");

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(Config.API_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .client(createOkHttpWithAuth())
            .build();
    apiInterface = retrofit.create(ApiInterface.class);
}
private OkHttpClient createOkHttpWithAuth() {
    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    if (BuildConfig.DEBUG) {
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    } else {
        interceptor.setLevel(HttpLoggingInterceptor.Level.HEADERS);
    }
    return new OkHttpClient.Builder()
            .addInterceptor(new SoundcloudInterceptor(token))
            .addNetworkInterceptor(interceptor)
            .build();
}

Getting response:

            File file = new File(Environment.getExternalStorageDirectory() + "/Music/test.mp3");

            // create RequestBody instance from file
            RequestBody requestFile =
                    RequestBody.create(MediaType.parse("multipart/form-data"), file);

            // MultipartBody.Part is used to send also the actual file name
            MultipartBody.Part body =
                    MultipartBody.Part.createFormData("audio", file.getName(), requestFile);

             Call<ResponseBody> call =  apiInterface.uploadTrack(requestFile, "Test", "private");
             call.enqueue(new Callback<ResponseBody>() {

                 @Override
                 public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                     //Log.v("Upload", "success" + response.body().toString());
                 }

                 @Override
                 public void onFailure(Call<ResponseBody> call, Throwable t) {
                     Log.e("Upload error:", t.getMessage());
                 }
             });

After request i'm receiving error 500:

05-13 12:36:23.407 6540-7186/com.example.soundcloud_app_android D/OkHttp: <-- 500 Internal Server Error https://api.soundcloud.com/tracks?client_id=**********&client_secret=**********&oauth_token=********** (3455ms)

Also tried passing file and MultipartBody.Part. In case of multipart i`m receiving error 422. So what is the right way to upload audio to soundcloud? I guess that i'm passing audio in wrong format and server doesn't recognise it.

Here example for upload image with retrofit 2. First, when create retrofit for multipart request, doesn't add converter factory.

public static APIMultipartService getMultipartService() {
    if (multipartService == null) {
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(DOMAIN)
                .build();
        multipartService = retrofit.create(APIMultipartService.class);
    }
    return multipartService;
}

Second, use RequestBody in interface.

public interface APIMultipartService {
    @POST("/api/v1/job/photo/add")
    Call<ResponseBody> uploadJobPhoto(@Body RequestBody body);}

And here example for create request body with file.

RequestBody body = RequestBody.create(MediaType.parse("image/*"), file);

                MultipartBuilder builder = new MultipartBuilder().type(MultipartBuilder.FORM);
                builder.addFormDataPart("pic", "photo.png", body);
                builder.addFormDataPart("jobId", id);
                builder.addFormDataPart("privateKey", privateKey);

                Call<ResponseBody> request = ApiService.getMultipartService().uploadJobPhoto(builder.build());
                request.enqueue(callbackPhotoRequest);

Try like that, maybe help you.
