First of all, it is not good, storing 300 images in drawable folder. It makes your apk larger. Put your images in any server, and then get links with json and then set your images in imageview's. You can use these libraries for loading images and caching: Picasso by square, Glide by Bumptech. This libraries help you for loading images easily, cropping, fitting and caching.
