Glass OS update

Glass was updating by itself automatically over the air. Glass was checking Google servers periodically for updates. When an update was available, Glass was downloading it to the device and was installing the update all by itself. That was happening under the condition of active battery charging and a reliable Wi-Fi connection.[9]

Why Apache Software License? ... For userspace (that is, non-kernel) software, we do in fact prefer ASL2.0 (and similar licenses like BSD, MIT, etc.) over other licenses such as LGPL. Android is about freedom and choice. The purpose of Android is promote openness in the mobile world, but we don't believe it's possible to predict or dictate all the uses to which people will want to put our software. So, while we encourage everyone to make devices that are open and modifiable, we don't believe it is our place to force them to do so. Using LGPL libraries would often force them to do so..
