What Is GmsCore?
GmsCore (previously called "MicroG" in the Vanced ecosystem) is a lightweight implementation of Google's framework APIs. For ReVanced non-root users, it provides:
- Google account sign-in
- Push notifications
- Account sync (subscriptions, history)
- Authentication tokens
When Is GmsCore Needed?
Non-root installations only. If you are using ReVanced with root (Magisk), GmsCore is not needed because the patched app replaces the original and uses the device's existing Google Play Services.
Common Issues
- Login failures: Ensure GmsCore is installed and updated to the latest version from the official ReVanced repository
- Battery drain: Disable battery optimization for GmsCore in device settings
- Notifications not working: Check that GmsCore is allowed to run in the background
