Thanks for sharing your article! Very informative.
Just a small note for other readers:
While Glide will suit your needs for many cases, if your app is really image-heavy, consider using Fresco by FB. This lib is more powerful, covers many aspects of working with images (caching, image transformations etc.) really smart.
But there are some downsides:
- this lib is heavy one
- learning curve. To achieve really good perf you are likely to write your own code and integrate it in Fresco(it’s architecture is very flexible)
