One of the most famous way to load images from any source into the app is by using an image loading library called Glide .

Follow the setup steps to get started. In the activity that you want an image to be loaded, declare an ImageView variable and use

ImageView imej = (ImageView) findViewById (R.id.imageID);
Glide.with(this).load("URL").into(imej);

If you wish to use the cache capabilities, add

.diskCacheStrategy(DiskCacheStrategy.SOURCE*)

between the .load() and .into() methods. Note that DiskCacheStrategy has 4 types. Choose wisely.
