Officially unveiled yesterday during Google I/O, Android L will be released sometime this fall. However, following Microsoft's example, Google has promised that it will launch a Developer Preview for Nexus 5 and Nexus 7 (2013) devices no later than today.
True to its promise, Google has just released the factory images for Android L Developer Preview for Nexus 5, which means that if you own this device, you will be among the first to experience the new features and improvements that the operating system brings.
Here is a quick recap of what you will get in this build. First of all, there's a new UI design called “material design,” the new ART runtime that replaces the old Dalvik compiler.
Then, there's the enhanced notifications, which now appear on the lockscreen, so you can interact with them without having to unlock the phone. You will be able to customize how these notifications should look and where they should appear. Last but not least, Project Volta is another major new feature that is expected to prolong your battery life.
Those who own a Nexus 5 and want to upgrade to Android L Developer Preview can do so now by downloading the factory image that has just been released by Google. You can find it on Google's developers website.
