I'm using Rails to create an API only app, storing data in MongoDB Atlas, and an Android app to make requests. One of my models has an image attribute and its value it's gonna be a link from Cloudinary, I was reading its documentation and found that they have SDKs for both Rails and Android. I don't know if it's better to use Android to upload the image, and then send the link to Rails, or use Rails to accept an image from the app and handle all the image uploading.
