## AI overview

This tutorial explains how to integrate the biometric-compose library into Android applications built with Jetpack Compose. It covers rememberAuthenticationLauncher, authentication callbacks, result handling, prompt configuration and customization, and authentication fallbacks.

## Source excerpt

Image generated using Perplexity In this article, we will learn how to integrate a new library biometric-compose into Android applications for Biometric integration. A new biometric-compose library simplifies the integration of biometrics into Compose-based applications. ImplementationDependencies implementation("androidx.biometric:biometric:1.4.0-alpha06") implementation("androidx.biometric:biometric-compose:1.4.0-alpha06")rememberAuthenticationLauncherrememberAuthenticationLauncher A composable function to streamline biometric authentication requests and callbacks directly in composables. It returns AuthenticationResultLauncher that we can use to initiate the authentication process. We need to pass a callback of type AuthenticationResultCallback . It will be called when an AuthenticationResult is available. A successful or error result will be delivered to AuthenticationResultCallback.onAuthResult , and failures will be delivered to AuthenticationResultCallback.onAuthAttemptFailed, which is set by a callback. The 👆callback will be executed on the main thread.fun AuthenticationResult.processAuthResult(){ when (this) { is AuthenticationResult.Success -> Log.d(TAG, "AuthenticationResult Success, \nAuth type: $authType, \nCrypto object: $crypto") is AuthenticationResult.Error -> Log.d(TAG,"AuthenticationResult Error, \nError code: $errorCode, \nErr string: $errString") is AuthenticationResult.CustomFallbackSelected -> { Log.d(TAG,"AuthenticationResult CustomFallbackSelected ${fallback.text}") } } }AuthenticationResultTypeAuthenticationResultTypeDemo AuthenticationResultTypeAuthenticationError (Error code)AuthenticationError (Error code)Demo AuthenticationError (Error code)🧑💻 Code: rememberAuthenticationLauncherval launcher = rememberAuthenticationLauncher( resultCallback = object : AuthenticationResultCallback { override fun onAuthResult(result: AuthenticationResult) { Log.d(TAG, "onAuthResult: $result") processAuthResult() } override fun onAuthAttemptFailed() { supe
