In this Android Video Tutorial I am guiding about four different libraries for loading images using URL:

• Universal Image Loader
• Picasso
• Glide
• Fresco

Along with I am explaining their description, performance and implementation procedure is also added in this tutorial.

You can use these libraries by adding following dependencies and their implementation code:

1. Universal Image Loader:-

compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

ImageLoaderConfiguration imageLoaderConfiguration = new ImageLoaderConfiguration.Builder(this).build();
        ImageLoader imageLoader = ImageLoader.getInstance();
        imageLoader.init(imageLoaderConfiguration);

        DisplayImageOptions options = new DisplayImageOptions.Builder()
                .showImageOnLoading(R.drawable.placeholder) // resource or drawable
                .showImageForEmptyUri(R.drawable.empty) // resource or drawable
                .showImageOnFail(R.drawable.failed) // resource or drawable
                .delayBeforeLoading(1000)
                .resetViewBeforeLoading(true)  // default
                .cacheInMemory(true) // default => false
                .cacheOnDisk(true) // default => false
                .build();

        imageLoader.displayImage(imageURI, ivImage, options, new ImageLoadingListener() {
            @Override
            public void onLoadingStarted(String imageUri, View view) {
                Toast.makeText(getApplicationContext(), "Loading Started", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
                Toast.makeText(getApplicationContext(), "Loading Failed", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
                Toast.makeText(getApplicationContext(), "Loading Complete", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onLoadingCancelled(String imageUri, View view) {
                Toast.makeText(getApplicationContext(), "Loading Cancelled", Toast.LENGTH_SHORT).show();
            }
        });

2. Picasso:-

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

Picasso.with(this)
                .load(imageURI)
                .placeholder(R.drawable.placeholder)
                .error(R.drawable.failed)
                .into(ivImage);

3. Glide:-

compile 'com.github.bumptech.glide:glide:3.6.1'

Glide.with(this)
                .load(imageURI)
                .placeholder(R.drawable.placeholder)
                .error(R.drawable.failed)
                .into(ivImage);

4. Fresco:-

compile 'com.facebook.fresco:fresco:0.14.1'

ControllerListener controllerListener = new ControllerListener() {
            @Override
            public void onSubmit(String id, Object callerContext) {
                Toast.makeText(ImageLoaderActivity.this, "Called before the image request is submitted", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFinalImageSet(String id, Object imageInfo, Animatable animatable) {
                Toast.makeText(ImageLoaderActivity.this, "When final image is loaded", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onIntermediateImageSet(String id, Object imageInfo) {
                Toast.makeText(ImageLoaderActivity.this, "When intermediate image is Loaded", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onIntermediateImageFailed(String id, Throwable throwable) {
                Toast.makeText(ImageLoaderActivity.this, "While intermediate image loading failed", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFailure(String id, Throwable throwable) {
                Toast.makeText(ImageLoaderActivity.this, "Image Loading failed", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onRelease(String id) {
                Toast.makeText(ImageLoaderActivity.this, "When controller releases the fetched Image", Toast.LENGTH_SHORT).show();
            }
        };

        Uri imageUri = Uri.parse(imageURI);
        DraweeController controller = Fresco.newDraweeControllerBuilder()
                .setUri(imageUri)
                .setControllerListener(controllerListener)
                .setAutoPlayAnimations(true)
                .build();

        sdvImage.setController(controller);

I had also attached image loader demo file, you can download it for further reference.
