With Android 5.0 Lollipop officially announced and the first release coming on November 3, we were waiting for this. Google has released the Android 5.0 Lollipop SDK and system images for developers to get working. Android 5.0 Lollipop marks an enormous update for Android, with dozens of enhancements and a new design language entitled Material Design. There’s very little in Android that isn’t affected by the update.
You can download the system images for yourself (see links below) but it should be noted that these are still preview images intended for developers to work with. That means that there may still be bugs in the software and you’ll have to install an official factory image before you can use the OTA update for Lollipop. If you’re a brave tinkerer, then go ahead and flash at your own risk.
How excited are you about Android 5.0 Lollipop?
