YASNAC (short for Yet Another SafetyNet Attestation Checker) is an Android app that demonstrates SafetyNet Attestation API.

The API key used by YASNAC has a quota of 10,000 times per day. If the quota is exhausted, you will see an error and you will not be able to use it until the quota is restored the next day.

SafetyNet is developed by Google, it provides a set of services and APIs. SafetyNet Attestation API provides a cryptographically-signed attestation, assessing the device's integrity. The app developer can use SafetyNet Attestation API to check if the device is an emulator, bootloader unlocked, system integrity compromised (root for example), etc.

This app uses SafetyNet Attestation API and displays the result.

In an production environment, the response of the SafetyNet Attestation API should be transfer to a remote server for verification. As a simple demonstration project, it is impractical to provide a server, so the verification step runs locally.

Anti-Features:

NonFreeComp (the application includes non-free components):
⇒ The app contains libraries of Google Mobile Services.

Download Source Issues

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).

10 Libraries detected:

Libraries:

Android Support v4 (Development Framework)
The Android Support Library is not actually a single library, but rather a collection of libraries that can roughly be divided into two groups: compatibility and component libraries. For details, please see Understanding the Android Support Library.
AndroidX Activity (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
Android Jetpack Annotations (Utility)
library that contains the annotations for Android Jetpack.
Jetpack Compose (Development Framework)
a framework to define UIs programmatically with composable functions that describe its shape and data dependencies.
Androidx Core (Utility)
a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.
Lifecycle (Utility)
perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
Android Activity Saved State (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
Android Jetpack VersionedParcelable (Utility)
Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely.
Google Mobile Services© (Development Framework)
Google Mobile Services in terms of the Android library refers to Google Play Services, a proprietary background service and API package for Android devices which is not part of the Android Open Source Project (AOSP). The library does not contain those services (i.e. it usually requires the Google Framework, often referred to as „GApps“, being installed on the device), but allows an app to communicate with them. Be aware this usually goes along with transferring at least parts of your personal data to the Google network.
kotlinx.coroutines (Utility)
library support for Kotlin coroutines.

Payment Modules:

None found
library support for Kotlin coroutines.
