[android] How to Upload Image file in Retrofit 2

I have an image of postman like below. How to do the same thing in Retrofit 2.

I've declared the interface like this.

@Multipart
@POST("/api/Pharmarcy/UploadImage")
Call<ResponseBody> uploadPrescriptionImage(
        @Query("accessToken") String token,
        @Query("pharmarcyRequestId") int pharmacyRequestedId,
        @Part MultipartBody.Part image);

It is quite easy. Here is the API Interface

public interface Api {

    @Multipart
    @POST("upload")
    Call<MyResponse> uploadImage(@Part("image\"; filename=\"myfile.jpg\" ") RequestBody file, @Part("desc") RequestBody desc);

}

And you can use the following code to make a call.

private void uploadFile(File file, String desc) {

        //creating request body for file
        RequestBody requestFile = RequestBody.create(MediaType.parse(getContentResolver().getType(fileUri)), file);
        RequestBody descBody = RequestBody.create(MediaType.parse("text/plain"), desc);

        //The gson builder
        Gson gson = new GsonBuilder()
                .setLenient()
                .create();


        //creating retrofit object
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(Api.BASE_URL)
                .addConverterFactory(GsonConverterFactory.create(gson))
                .build();

        //creating our api 
        Api api = retrofit.create(Api.class);

        //creating a call and calling the upload image method 
        Call<MyResponse> call = api.uploadImage(requestFile, descBody);

        //finally performing the call 
        call.enqueue(new Callback<MyResponse>() {
            @Override
            public void onResponse(Call<MyResponse> call, Response<MyResponse> response) {
                if (!response.body().error) {
                    Toast.makeText(getApplicationContext(), "File Uploaded Successfully...", Toast.LENGTH_LONG).show();
                } else {
                    Toast.makeText(getApplicationContext(), "Some error occurred...", Toast.LENGTH_LONG).show();
                }
            }

            @Override
            public void onFailure(Call<MyResponse> call, Throwable t) {
                Toast.makeText(getApplicationContext(), t.getMessage(), Toast.LENGTH_LONG).show();
            }
        });
    }

Source: Retrofit Upload File Tutorial.

For those with an inputStream, you can upload inputStream using Multipart.

@Multipart
@POST("pictures")
suspend fun uploadPicture(
        @Part part: MultipartBody.Part
): NetworkPicture

Then in perhaps your repository class:

suspend fun upload(inputStream: InputStream) {
   val part = MultipartBody.Part.createFormData(
         "pic", "myPic", RequestBody.create(
              MediaType.parse("image/*"),
              inputStream.readBytes()
          )
   )
   uploadPicture(part)
}

To get an input stream you can do something like so.

In your fragment or activity, you need to create an image picker that returns an InputStream. The advantage of an InputStream is that it can be used for files on the cloud like google drive and dropbox.

Call pickImage() from a View.OnClickListener or onOptionsItemSelected.

    private fun pickImage() {
        val intent = Intent(Intent.ACTION_GET_CONTENT)
        intent.type = "image/*"
        startActivityForResult(intent, PICK_PHOTO)
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == PICK_PHOTO && resultCode == Activity.RESULT_OK) {
            try {
                data?.let {
                    val inputStream: InputStream? =
                        context?.contentResolver?.openInputStream(it.data!!)
                    inputStream?.let { stream ->
                        itemViewModel.uploadPicture(stream)
                    }
                }
            } catch (e: FileNotFoundException) {
                e.printStackTrace()
            }
        }
    }

    companion object {
        const val PICK_PHOTO = 1
    }

Totally agree with @tir38 and @android_griezmann. This would be the version in kotlin:

interface servicesEndPoint {
@Multipart
@POST("user/updateprofile")
fun updateProfile(@Part("user_id") id:RequestBody, @Part("full_name") other:fullName, @Part image: MultipartBody.Part, @Part("other") other:RequestBody): Single<UploadPhotoResponse>

companion object {
        val API_BASE_URL = "YOUR_URL"

        fun create(): servicesPhotoEndPoint {
            val retrofit = Retrofit.Builder()
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .baseUrl(API_BASE_URL)
                .build()
            return retrofit.create(servicesPhotoEndPoint::class.java)
        }
    }
}

// pass it like this
val file = File(RealPathUtils.getRealPathFromURI_API19(context, uri))  
val requestFile: RequestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file)

// MultipartBody.Part is used to send also the actual file name
val body: MultipartBody.Part = MultipartBody.Part.createFormData("image", file.name, requestFile)

// add another part within the multipart request
val fullName: RequestBody = RequestBody.create(MediaType.parse("multipart/form-data"), "Your Name")

servicesEndPoint.create().updateProfile(id, fullName, body, fullName)

To obtain the real path, use RealPathUtils. Check this class in the answers of @Harsh Bhavsar in this question: How to get the Full file path from URI.

To getRealPathFromURI_API19 you need permissions of READ_EXTERNAL_STORAGE

Retrofit 2.0 solution

@Multipart
@POST(APIUtils.UPDATE_PROFILE_IMAGE_URL)
public Call<CommonResponse> requestUpdateImage(@PartMap Map<String, RequestBody> map);

and

    Map<String, RequestBody> params = new HashMap<>();

    params.put("newProfilePicture" + "\"; filename=\"" + FilenameUtils.getName(file.getAbsolutePath()), RequestBody.create(MediaType.parse("image/jpg"), file));



 Call<CommonResponse> call = request.requestUpdateImage(params);

you can use
image/jpg image/png image/gif

@Multipart
@POST(Config.UPLOAD_IMAGE)
Observable<Response<String>> uploadPhoto(@Header("Access-Token") String header, @Part MultipartBody.Part imageFile);

And you can call this api like this:

   public void uploadImage(File file) {
     // create multipart
     RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
    MultipartBody.Part body = MultipartBody.Part.createFormData("image", file.getName(), requestFile);

    // upload
    getViewInteractor().showProfileUploadingProgress();

    Observable<Response<String>> observable = api.uploadPhoto("",body);

    // on Response
    subscribeForNetwork(observable, new ApiObserver<Response<String>>() {
        @Override
        public void onError(Throwable e) {
            getViewInteractor().hideProfileUploadingProgress();
        }

        @Override
        public void onResponse(Response<String> response) {

            if (response.code() != 200) {
                Timber.d("error " + response.code());
                return;
            }
            getViewInteractor().hideProfileUploadingProgress();
            getViewInteractor().onProfileImageUploadSuccess(response.body());

        }
    });

}

Using Retrofit 2.0 you may use this:

@Multipart
    @POST("uploadImage")
    Call<ResponseBody> uploadImage(@Part("file\"; fileName=\"myFile.png\" ")RequestBody requestBodyFile, @Part("image") RequestBody requestBodyJson);

Make a request:

File imgFile = new File("YOUR IMAGE FILE PATH");
RequestBody requestBodyFile = RequestBody.create(MediaType.parse("image/*"), imgFile);
RequestBody requestBodyJson = RequestBody.create(MediaType.parse("text/plain"),
                    retrofitClient.getJsonObject(uploadRequest));



//make sync call
Call<ResponseBody> uploadBundle = uploadImpl.uploadImage(requestBodyFile, requestBodyJson);
Response<BaseResponse> response = uploadBundle.execute();
