Android L Guide

Google unveiled the latest Android L update at the I/O conference about a month ago. Android L is the biggest update to the OS since the Ice Cream Sandwich update which was several years ago. We have covered the major new features in detail if you want to check out what the L update has to offer. From a complete visual overhaul to over 2000 new APIs, Android L is shaping up to be the update to look out for in the fall.

Currently Android L is not available for the general consumer. The preview was released for developers to test out their apps as well as preview the OS. Over the course of next few months Google will iron out the kinks in the OS and will then roll it out for the Nexus devices in the fall. However if you’re feeling adventurous, you can go ahead and try the developer preview of Android L yourself. Google has provided factory images for Nexus 5 and Nexus 7.
