microg/GmsCore

This system is an open-source implementation of Google Play Services (microG) that provides a compatible API surface for Android applications. It implements a wide range of Google APIs, including authentication, location, ads, and safety checks, using internal inter-process communication (IPC) mechanisms. The codebase serves as a functional replacement for proprietary Google services, enabling apps to interact with Google's ecosystem while maintaining user privacy and offering alternative backends like Mapbox or Huawei Mobile Services.

This period focused on expanding the microG codebase to support a wide array of Google Play Services APIs, including location, wearable, GCM, and vision features. The work involved implementing new AIDL interfaces, data models, and client libraries to emulate or interact with Google's backend services. Additionally, the project modernized its build system with Gradle and introduced internal tools for UI and self-checking.

This period focused on implementing a wide array of Google Play Services APIs, including authentication, location, maps, and security features. The work involved adding AIDL interfaces, data models, and client classes to support services like DroidGuard, FIDO2, SafetyNet, and Firebase Auth. The codebase expanded its internal infrastructure to handle these new remote procedure calls and device capabilities.

71 changes

This period focused on expanding the Google Play Services API surface by adding AIDL interfaces and Java/Kotlin stubs for numerous new features, including Semantic Location, Google Fit, Face Detection, and Find My Device. The work established the internal IPC contracts and data models required for these services, while also refactoring existing authentication and location reporting logic.

microg/GmsCore was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point the surveyor at a repository you know and see whether you agree with it.
