Android: Google is rolling out an update for Chrome on Android that will allow you to easily download web pages, video and music for offline viewing.
The update is rolling out on Google Play over the next couple of days, and alongside the saving full web pages for offline viewing, it also packs in the ability to download video and music from sites. To save a page, just tap the overflow button on the top right and select the save icon. For videos and music, you'll see an icon pop up next to the scrubber to download the media. You can access everything you download from the Downloads section in that same overflow menu.
