Retrofit2: Upload an Image with some Form Data-Android

Question

The above screenshot contain the Post method and Response from the server.. here i am trying to upload an image with some data to my server(catch the image from gallery or camera)..

I am trying to achieve this via retrofit2. trying some methods from Internet... but i can't get the right way to done it

new in retrofit2. so I cant done this.

How to Create retrofit2 interface and handle the response.. please help

Edit My Try

Code in Activity

  ProofAPI service =  retrofit.create(ProofAPI.class);
        File file=new File(sdCard.getAbsolutePath()+fNameAd);
        MultipartBody.Part filePart = MultipartBody.Part.createFormData("proof", file.getName(), RequestBody.create(MediaType.parse("image/*"), file));

 HashMap<String, String> map = new HashMap<>();
        map.put("userId", user_id);
        map.put("proofDocId", idproofno);
        map.put("proofFilename", proofFilename);
        map.put("docType", docType);
    Call<ProofResp> call = service.uploadFileWithPartMap(map,filePart);
        call.enqueue(new Callback<ProofResp>() {
            @Override
            public void onResponse(Call<ProofResp> call, Response<ProofResp> response) {
                Toast.makeText(getApplicationContext(),response.body().getMessage(),Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFailure(Call<ProofResp> call, Throwable t) {
                Toast.makeText(getApplicationContext(),"fjkds",Toast.LENGTH_SHORT).show();
            }
        });

Retofit2 Interface -> ProofAPI

@Multipart
    @POST("rest-proof-upload")
    Call<ProofResp> uploadFileWithPartMap(
            @PartMap() Map<String, String> partMap,
            @Part MultipartBody.Part file
    );

and I get the failure message. Is this the right way .. Anyone please explain the correct way to achive it.

Just edit question with my try to achive it.. please review.. Now I am getting onFailure's toast message — Adarsh, Oct 05 '16 at 05:46
yes , here is the code : MultipartBody.Part filePart = MultipartBody.Part.createFormData("proof", file.getName(), RequestBody.create(MediaType.parse("image/*"), file)); — Adarsh, Oct 05 '16 at 05:54

I have done something like below :--

My interface

    @Multipart
    @POST("your_path")
    Call<ProofResp> uploadFileWithPartMap(@PartMap Map<String, RequestBody> params,
    @Part("profile_pic\"; filename=\"image.jpeg\"") RequestBody file);

Now I am creating partmap like below

 HashMap<String, RequestBody> map = new HashMap<>();
 map.put("userId", toRequestBody(userId));

My RequestBody function is below :--

public RequestBody toRequestBody(String value) {
    RequestBody body = RequestBody.create(MediaType.parse("text/plain"), value);
    return body;
}

Now the for the image part

RequestBody file=RequestBody.create(MediaType.parse("image/jpeg"),
createTempFile(your_bitmap));

Now the createTempFile funtion

private File createTempFile(Bitmap bitmap) {
        File file = new File(getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES), System.currentTimeMillis()
                + "_image.jpeg");
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 0 /*ignored for PNG*/, bos);
        byte[] bitmapdata = bos.toByteArray();
//write the bytes in file

        try {
            FileOutputStream fos = new FileOutputStream(file);
            fos.write(bitmapdata);
            fos.flush();
            fos.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return file;
    }

Now send this file and map to your interface and you will get the response.Hope this above idea will help you to solve your problem.
