The official Android 5.0 Lollipop upgrade for your phone may be weeks away, but Google has delivered all the ingredients for you to make Lollipop-ready apps. The search firm has released both the finished Lollipop developer kit and a fresh batch of stripped-down Android test releases for Nexus 5 and 7 devices. There’s also a new round of Material Design guidelines and assets to make sure apps look at home in Google’s flatter aesthetic. This won’t help much if you just want to try all the whiz-bang features, but you’ll definitely want to hit the source links if you’re a software creator.
