HttpPost httppost = new HttpPost(URL);
MultipartEntity entity = new MultipartEntity();
entity.addPart("title", new StringBody("yourfile", Charset.forName("UTF-8")));
File myFile = new File(Environment.getExternalStorageDirectory(), file);
FileBody fileBody = new FileBody(myFile);
entity.addPart("file", fileBody);
httppost.setEntity(entity);

Answer 3

Using retrofit 2 library to make the network call, you can send the image to the server using multipart First : create a method like the following in your interface

@Multipart
@POST("upload")
Call<ApiResponse> uploadImage(@Part MultipartBody.Part image);

Second : In your Activity where you get the picture use the following code before you call the uploadImage() method

File imageFile = new File(imagePath);
    RequestBody requestBody =
            RequestBody.create(MediaType.parse("multipart/form-data"), imageFile);
    MultipartBody.Part formData =
            MultipartBody.Part.createFormData("file", imageFile.getName(), requestBody);

Third : call the uploadImage() method and pass the formData as the parameter
