Android library to verify application environments.

Make sure every API call from a device is safe and trusted.

Instantly detect rooted devices or emulators.

The library sends a set of signals to the server.

The server verifies safety of the application environment.

2. API keys
3. Demo App

If your version of Gradle is earlier than 7, add these lines to your build.gradle.

allprojects {	
  repositories {
  ...
  maven { url 'https://jitpack.io' }	
}}

If your version of Gradle is 7 or newer, add these lines to your settings.gradle.

repositories {
  ...
  maven { url "https://jitpack.io" }
}

This library depends on kotlin-stdlib, fingerprint-android

Add these lines to build.gradle of a module.

If your application is written in Java, add kotlin-stdlib dependency first (it's lightweight and has excellent backward and forward compatibility).

dependencies {
  implementation "com.github.fingerprintjs:fingerprint-android:1.2"
  implementation "com.github.fingerprintjs:aev:1.0.2"
  // Add this line only if you use this library with Java
  implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}

A free API keys are required to connect to our Application Environment Verification API. Use the Public one on the client side, and the Secret one on the server side.

To get your API keys, please ping us on Discord or email us at [email protected] (just type API keys in the email subject, no need to compose a body)

Kotlin

// Initialization
val aevClient = AevClientFactory.getInstance(
    applicationContext,
    YOUR_PUBLIC_API_KEY
)


// Get the RequestID
aevClient.getRequestId(
                listener = { requestId ->
                    // Handle the string with requestId
                },
                errorListener = { error ->
                    // Handle the error string
                })
