Tap2iD SDK for Android - Integration

Prerequisites

Your development environment must meet these requirements:

• AS Android Studio Panda 4 or latest
• ☕ JDK Version: 17.0.7
• 🔧 Gradle Wrapper: gradle-8.14.3-bin.zip
• 📱 Minimum OS Version: Android 10 (API level 29)

Add the Credence ID Maven repository

Add the Credence ID Nexus repository to your project's settings.gradle. The SDK packages resolve from this repository during the build.

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        // ...

        maven {
            url = uri("https://nexus.credenceid.com/repository/credenceid-sdk-group/")
        }
    }
}

Add the Tap2iD SDK Dependency

Include the SDK dependency in the build.gradle.kts file of your app module.

dependencies {
    implementation("com.credenceid:tap2idSdk:2.0.0")
}

Verify SDK in External Dependencies

After syncing, verify this package appears in your app's External Dependencies:

Initialize the SDK with your license key

Generate your license key on the Tap2iD SDK License Key page, then pass it when you initialize the SDK. Do not hard-code the key. Store it in local.properties or secure storage.

val config = SdkConfig(
    context   = applicationContext,
    apiKey    = BuildConfig.TAP2ID_API_KEY,   // read from local.properties
    transport = TransportType.BLE
)
Tap2iDSdk.initSdk(config, object : InitSdkResultListener {
    override fun onSuccess() { /* ready */ }
    override fun onError(error: String) { /* handle */ }
})
