Updating ImageView based on URL

I have spent a lot of time trolling through multiple different threads concerning this topic, but I have yet to find an answer that works well with my code (Android SDK 23, in 2016). A lot of the answers are deprecated, and others just flat-out don't work like they're supposed to, and I was wondering if I could get a solid answer on this:

I am trying to include a Pokemon sprite (static image) in my program from Serebii. nums is a variable indicating the Pokemon's dex number (this one functions correctly, I promise). And this code is running in the main UI thread, which I know is frowned upon, but right now I'm trying to get the image loading, and then the smoothness of the app down. I don't really need a Bitmap, per se, but I need my ImageView to update and display the image given by the URL. How do I do it?

URL url = null;
try {
     url = new URL("http://www.serebii.net/xy/pokemon/" + nums + ".png");
} catch (MalformedURLException e) {
  e.printStackTrace();
}
Bitmap bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
mImageView.setImageBitmap(bmp);

Use the Piassco library for it..Library link

For setting the Bitmap on the ImageView

Picasso.with(getContext()).load("your url").into(new Target() {
        @Override
        public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
            //do what ever you want with your bitmap 
          imgView.setImageBitmap(loadedImage);///imgView is use to set the image in it
        }

        @Override
        public void onBitmapFailed(Drawable errorDrawable) {

        }

        @Override
        public void onPrepareLoad(Drawable placeHolderDrawable) {

        }
    });

And another method of Picasso :-

Picasso.with(this)
        .load("your_image_url")
        .placeholder(R.drawable.no_image)
        .error(android.R.drawable.stat_notify_error)
        .networkPolicy(NetworkPolicy.OFFLINE)//user this for offline support
        .into(YOUR_IMAEGVIEW);

OR

You can also use the Universal Image Loader..Here is the link Universal image loader

ImageLoader imageLoader = ImageLoader.getInstance(); // Get singleton instance
            ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(getActivity()));
            imageLoader = com.nostra13.universalimageloader.core.ImageLoader.getInstance();
              DisplayImageOptions options = new DisplayImageOptions.Builder()
                    .showImageOnLoading(R.drawable.YOUR_DRAWABLE)
                    .showImageForEmptyUri(R.drawable.YOUR_DRAWABLE)
                    .showImageOnFail(R.drawable.YOUR_DRAWABLE)
                    .cacheInMemory(true)
                    .cacheOnDisk(true)
                    .considerExifParams(true)
                    .build();

imageLoader.displayImage("your_image_url", YOUR_IMAGEVIEW, null);

You can try using Picasso as:

Picasso.with(context)
          .load(url)
          .into(imageview);

Or use Universal Image loader as:

 ImageLoader imageLoader = new  ImageLoader(context);
 imageLoader.displayImage(imageUri, imageView);

You can use Picasso Library to load images.
a) Add Gradle into your project.

compile 'com.squareup.picasso:picasso:2.5.2'

b) Usage

Picasso.with(context).load("http://www.serebii.net/xy/pokemon/" + nums + ".png").into(imageView);

Also there are another libraries, you can use like Fresco by Facebook, Universal Image loader

Just use Picasso library, it will do all your image loading. You only need to provide the url of the image correctly.

String url = "http://www.serebii.net/xy/pokemon/" + nums + ".png";

Picasso.with(yourContext)
    .load(url)
    .into(mImageView);
