回答1:
You should upload your file like this
File file1 = new File(mediaPath);
int id=24;
// File file2 = new File(mediaPath);
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file1);
MultipartBody.Part body = MultipartBody.Part.createFormData("photo", file.getName(), requestFile);
RequestBody requestBodyid = RequestBody.create(MediaType.parse("multipart/form-data"),id);
ApiService getResponse = ApiClient.getClient().create(ApiService.class);
// Call<ServerResponse> call = getResponse.uploadFile(fileToUpload1);
Call<ServerResponse> call = getResponse.uploadFile(body,requestBodyid);
instead of
RequestBody requestBody1 = RequestBody.create(MediaType.parse("image/*"), file1);
EDIT: You forgot to create request body for the id. Add these to the code.
RequestBody requestBodyid = RequestBody.create(MediaType.parse("multipart/form-data"), id);
Where id is your id, i.e id=24.

If your problem is that progress bar is not getting hidden, you are not calling progressDialog.dismiss(); in onFailure function.
