安卓设备可以免费使用AOSP，但安装GMS必须得到谷歌授权
如果安卓机想要在系统中内置GMS，那么就必须通过谷歌的CTS/GTS兼容性认证，这样才能够预装GMS并融入谷歌生态当中。
安卓机的生态依赖谷歌，没有GMS的话，恐怕寸步难行。而GMS并不是谷歌免费提供的，设备厂商需要缴纳一笔费用，得到谷歌的授权，
才能在系统内置GMS，否则属于非法。
某些国产手机就采取了一个折衷的方法——对GMS开启签名白名单。手机系统不需要root，就可以将GMS框架直接安装到系统当中.
现在谷歌出手了。想不缴授权费就白嫖GMS,GMS不再允许通过签名白名单的方法、以User App的形式直接安装到系统当中
While the Android Open Source Project (AOSP) provides common, device-level functionalities such as email and calling,
GMS is not part of AOSP. GMS is only available through a license with Google and delivers a holistic set
of popular apps and cloud-based services.
Google Mobile Services (GMS) is a collection of proprietary applications and application programming interfaces (APIs) services from Google that are typically pre-installed on Android devices,
such as smartphones, tablets, and smart TVs. GMS is not a part of the Android Open Source Project (AOSP), which means an Android manufacturer needs to obtain a license from Google in order to
legally pre-install GMS on an Android device. This license is provided by Google without any licensing fees except in the EU
