eing a Material Design lover, I get put off by that default flat Toolbar with no shadow or elevation. It’s alright on Lollipop devices as it gives us a nice shadow by default, but pre Lollipop doesn’t. While that’s too bad, we can take care of that real quick! After you’re done with this post, your Toolbars on pre Lollipop will never be plain and boring again!

While sending a photo through WhatsApp, I noticed the ‘Attach’ button performs a neat Circular Reveal effect. My phone being JellyBean, I was surprised to see a Lollipop only transition. Thanks to a neat library, we can mimic the exact same thing for pre Lollipop too.
If you’re a Pinterest user, you would have noticed their rather creative grid layout. That is a Masonry Layout. It works by placing elements in optimal position based on available vertical space, sort of like a mason fitting stones in a wall.
