SPIC (Simple Play Integrity Checker) is an Android application designed to illustrate the functionality of the Play Integrity API, along with the now-deprecated SafetyNet Attestation API. This app serves as a practical demonstration for developers interested in understanding how these APIs can be used to verify device integrity.

With SPIC, users can check the integrity verdict directly on their device or opt to send this data to a remote server for validation. It's important to note that the remote server must be self-hosted at present, as there is no provided service for this purpose.

As an open-source project, SPIC offers transparency and learning opportunities for the community. The source code for both the Android application and the server component is available on GitHub. You can access the Android app's code at /herzhenr/SPIC-android and the server implementation at /herzhenr/SPIC-server.

This tool is particularly useful for developers looking to integrate device integrity checks into their applications, ensuring a secure environment for their users.
