The next major version of Android is coming sometime this fall. Known right now as Android L, it was one of the key announcements as last week’s keynote event that kicked off the Google I/O 2014 developer conference. System images for both the Google Nexus 5 and Google Nexus 7 (2013) were released to AOSP the day after the keynote. Google has now released system images for more Nexus devices.
Here is the list of the devices that you can now update to the Android L Preview:
- Google Nexus 4: https://android.googlesource.com/device/lge/mako/+/l-preview
- Google Nexus 5: https://android.googlesource.com/device/lge/hammerhead/+/l-preview
- Google Nexus 7 (2012) Wi-Fi: https://android.googlesource.com/device/asus/grouper/+/l-preview
- Google Nexus 7 (2012) GSM: https://android.googlesource.com/device/asus/tilapia/+/l-preview
- Google Nexus 7 (2013) Wi-Fi: https://android.googlesource.com/device/asus/flo/+/l-preview
- Google Nexus 7 (2013) LTE: https://android.googlesource.com/device/asus/deb/+/l-preview
- Google Nexus 10: https://android.googlesource.com/device/samsung/manta/+/l-preview
Keep in mind that these Android L previews are geared primarily at developers to allow them to better understand the changes coming to Android so that they can update their apps to ensure that there are no issues when users update their devices.
Android L is a major update to Google’s mobile operating system. Its Material Design Guidelines introduced a new flatter user interface that makes much more use of the card interface first introduced with Google Now. Under the hood, Android is switching to the ART runtime compiler for improved performance and battery life, a 64-bit architecture and further battery life improvements (under the Volta project).
