SPIC (Simple Play Integrity Checker) is an innovative Android application designed to showcase the functionality of the Play Integrity API alongside the now-deprecated SafetyNet Attestation API. This app serves as a practical tool for developers and security enthusiasts interested in understanding and implementing integrity checks on Android devices.

The primary feature of SPIC is its ability to retrieve an integrity verdict from both the Play Integrity and SafetyNet Attestation APIs. Users have the flexibility to verify this verdict directly on their device or transmit it to a remote server for external validation. It's important to note that the remote server component requires self-hosting at the moment, offering users complete control over their data and validation processes.

As an open-source project, SPIC fosters transparency and community involvement. The source code for both the Android application and the server implementation is readily available on GitHub, under the repositories /herzhenr/SPIC-android and /herzhenr/SPIC-server, respectively. This accessibility encourages developers to contribute, modify, and enhance the tool, ensuring it remains up-to-date with the latest security standards and practices.

By providing a clear demonstration of how to use these APIs, SPIC not only aids in the education of developers but also assists in maintaining the integrity and security of Android applications. Whether you're looking to integrate these APIs into your own projects or simply want to understand how they work, SPIC offers a valuable resource for exploring Android security measures.
