Google basic service framework, Google contact synchronization service interface, Google calendar synchronization service interface, and Google App Store.
The full name of Google Service Framework is Google Mobile Service, which includes application packages, which are the various Google applications we want to use. Although Android is open source and free, Google's applications are not included in it. They are all Google's intellectual property. Therefore, manufacturers who pre-install Google applications need to enter into a paid partnership with Google. Coupled with other reasons, many domestic mobile phone manufacturers do not bring their own Google suite.
Extended information:
First of all, it provides the underlying communication service, which can be used to push some messages and synchronize contact data.
Secondly, if you want to experience Google’s entire set of software services, you need to install the Google framework first. From Google Maps, Google Voice, Google Keep, to the Google Play app market that AppSo always recommends, it is required.
Another point is that many applications and games use the Google Play service program to implement genuine verification and automatic login functions, so many large-scale games also require the support of Google services.
