The μG (also called microG) is a thin and open source re-implementation of Google Play Services for Android. The following information is partially reposted from this forum discussion.
To install microG on your device with emteria.OS, following steps have to be performed:
- Navigate to Settings -> Emteria settings and enable “Signature spoofing”
- Open F-Droid and add the microG repository (see https://microg.org/fdroid/repo) to download microG related files.
- Follow installation steps at the official microG website
- Android applications requiring Google Play Services should install/work fine. Please note, that the microG project is in heavy development stage, so no stability can be guaranteed by emteria.
- Install FakeStore from F-Droid to get access to third-party applications.
The FakeStore emulates that the real PlayStore is installed in Android, so that you can install most paid for apps that DO NOT call on any PlayStore API’s. There are a few other steps that advance users can do to add paid apps to emteria.OS:
- On your Android phone you can install a app called APKShare that will make backups of the app onto your phone.
- Take those app(s) and install them via adb.
As stated above, there is a chance your paid games or apps may not work due to the need of full API use from PlayStore.
