Retrofit 2 file down/upload

Question

I\'m trying to down/upload a file with retrofit 2 but can\'t find any tutorials examples on how to do so. My code for downloading is:

@GET(\"documents/checko         


        

Answer 1

I am using retrofit 2.0.0-beta2 and I had an issue uploading image by using multipart request. I solved it by using this answer: https://stackoverflow.com/a/32796626/2915075

The key for me was to use standard POST with MultipartRequestBody instead of @Multipart annotated request.

Here is my code:

Retrofit service class

@POST("photo")
Call uploadPhoto(@Body RequestBody imageFile, @Query("sessionId"));

Usage from activity, fragment:

RequestBody fileBody = RequestBody.create(MediaType.parse("image/jpeg"), imageFile);
MultipartBuilder multipartBuilder = new MultipartBuilder();
multipartBuilder.addFormDataPart("photo", imageFile.getName(), fileBody);
RequestBody fileRequestBody = multipartBuilder.build();

//call
mRestClient.getRetrofitService().uploadProfilePhoto(fileRequestBody, sessionId);
