Question

Answer 1

Step 1: First initialize service class

public interface ImageUploadService {  
    @Multipart
    @POST("upload")
    Call upload(
        @Part("description") RequestBody description,
        @Part MultipartBody.Part file
    );
}

Step 2: in next step use this where you want to upload image or file

private void uploadFile(Uri fileUri) {  
    // create upload service client
    FileUploadService service =
            ServiceGenerator.createService(ImageUploadService.class);

    // https://github.com/iPaulPro/aFileChooser/blob/master/aFileChooser/src/com/ipaulpro/afilechooser/utils/FileUtils.java
    // use the FileUtils to get the actual file by uri
    File file = FileUtils.getFile(this, fileUri);

    // create RequestBody instance from file
    RequestBody requestFile =
            RequestBody.create(
                         MediaType.parse(getContentResolver().getType(fileUri)),
                         file
             );

    // MultipartBody.Part is used to send also the actual file name
    MultipartBody.Part body =
            MultipartBody.Part.createFormData("picture", file.getName(), requestFile);

    // add another part within the multipart request
    String descriptionString = "hello, this is description speaking";
    RequestBody description =
            RequestBody.create(
                    okhttp3.MultipartBody.FORM, descriptionString);

    // finally, execute the request
    Call call = service.upload(description, body);
    call.enqueue(new Callback() {
        @Override
        public void onResponse(Call call,
                               Response response) {
            Log.v("Upload", "success");
        }

        @Override
        public void onFailure(Call call, Throwable t) {
            Log.e("Upload error:", t.getMessage());
        }
    });
}

Step 3: you can use like this

uploadFile(Uri.fromFile(new File("/sdcard/cats.jpg")));
