Retrofit 2 Multipart image upload with data

Question

Hello everyone I want to post image and other data through Retrofit2. I am sending data with one image.

All the other info is storing but my image is

Answer 1

We test api in Postman... So my Create Post Answer includes (all Dynamic)

• Headers
• Simple Strings
• Single Image
• Array Of Images
• Array Of Categories
• Array Of Features

Almost all things

Below is the Postman image for api testing...

• Headers Image

So for this ... Below is my Api...

@POST("post-create")
    Call getPostCreateBodyResponse(
            @Header("Accept") String accept,
            @Header("Authorization") String authorization,
            @Body RequestBody file
    );

Now Retrofit Client area--->

private Retrofit retrofit;

// This is Client
private RetrofitClient() {

        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

        httpClient.connectTimeout(100, TimeUnit.SECONDS);
        httpClient.readTimeout(100,TimeUnit.SECONDS);
        httpClient.writeTimeout(100,TimeUnit.SECONDS);
        httpClient.addInterceptor(logging);  // <-- this is the important line!

        retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .client(httpClient.build())
                .build();
    }

This is the way I Made the Request...

/*
     * -------------- Retrofit post Create single featured Image Working with MultipartBody -----------
     * */

    progressDialog.show();

    MultipartBody.Builder builder = new MultipartBody.Builder().setType(MultipartBody.FORM);

    builder.addFormDataPart("title", "3 room Current Free")
            .addFormDataPart("location", "Dhaka")
            .addFormDataPart("latitude", "23.7515")
            .addFormDataPart("longitude", "90.3625")
            .addFormDataPart("condition", "1")
            .addFormDataPart("rent_amount", "123456")
            .addFormDataPart("is_negotiable", "0")
            .addFormDataPart("available_from", "2018-10-15");

    // Categories
    for (int categoryId : categories) {
        builder.addFormDataPart("categories[]", String.valueOf(categoryId));
    }
    // Features
    for (Integer featureId : features) {
        builder.addFormDataPart("features[]", String.valueOf(featureId));
    }

    // featured Image
    if (photoPaths.get(0) != null) {
        File featured_image = new File(photoPaths.get(0));
        if (featured_image.exists()) {

// If you want to use Bitmap then use this

            Bitmap bmp = BitmapFactory.decodeFile(featured_image.getAbsolutePath());
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 30, bos);

            builder.addFormDataPart("featured_photo", featured_image.getName(), RequestBody.create(MultipartBody.FORM, bos.toByteArray()));


// If you want to use direct file then use this ( comment out the below part and comment the above part )

            //builder.addFormDataPart("featured_photo", featured_image.getName(), RequestBody.create(MultipartBody.FORM, featured_image));
        }
    }

    // Images
    for (String photoPath : photoPaths) {
        if (photoPath != null) {
            File images = new File(photoPath);
            if (images.exists()) {
                builder.addFormDataPart("images[]", images.getName(), RequestBody.create(MultipartBody.FORM, images));
            }
        }
    }

    RequestBody requestBody = builder.build();
    Call call = RetrofitClient.getInstance().getApi().getPostCreateBodyResponse(Accept, Authorization, requestBody);
    call.enqueue(new Callback() {
        @Override
        public void onResponse(Call call, Response response) {
            progressDialog.dismiss();
            Log.d(TAG, "onResponse: response code: retrofit: " + response.code());
        }

        @Override
        public void onFailure(Call call, Throwable t) {

        }
    });
