You already worked with Glide before? You’ll profit from our extensive code snippets and can improve your existing code base. Additionally, the book illustrates various optimizations for an even better user experience.
Every code snippet in the book has been tested. The example project is provided for free as an extra download. We recommend to download it from Leanpub's book extra section and check the full code base as you move through the book. We try to keep the code snippets in the book as short as possible. If more context is necessary, the example app's code provides it.
