So, the code for the activity_main.xml file is: Here in the UI, we will be having one ImageView and one TextView. So, add the USE_FINGERPRINT permission in your manifest file: īefore moving towards the coding part of the app, let’s write the code for the UI part.

Android 6.0.Īfter creating the project, please ensure that your device has some kind of authentication other than fingerprint because the Fingerprint Authentication will work in that case only.Īdd the permission of fingerprint in your androidmanifest.xml file. Now let’s move on to the implementation part of the same.Ĭreate a new project in Android Studio and name it according to your choice.

So, we have seen the theory of Fingerprint Authentication. Call the authenticate method of the FingerprintManger class and implement methods to handle the callbacks.įingerprint Authentication Implementation.With the help of the key generated and stored in the Keystore container, initialize the instance of the Cipher class and use this instance to create a CryptoObject and assign it to FringerprintManager instance that you have created earlier.After that, generate an encryption key with the help of keyGenerator class and store it in the Keystore container. So, create an instance of the Keystore to gain access of the Android Keystore container. You have to gain access to the storage area that is used to store the cryptographic keys on Android devices i.e.Then, create an instance of the FingerprintManager class.So, we have to check if the lock screen of the device is protected by a PIN, pattern or password. As fingerprints can only be registered on the devices which have its lock screen protected by a PIN, pattern or password.Requesting Fingerprint Authentication permission within the project’s manifest file.

The whole process of Fingerprint Authentication can be summarized into the below steps: Como o prprio Google explica na pgina oficial do Android, configuraes do desenvolvedor eles so uma seo oculta dentro do Aplicativo de configurao do sistema no Android, dedicado aos criadores de aplicativos pode configurar certos comportamentos do sistema, o que pode ajudar quando desenvolver e depurar aplicativos. Now, we can easily implement Fingerprint Authentication in our application in the devices having the Fingerprint sensor. With the release of Android 6.0 (Android M), there has been a significant amount of changes to the APIs, one of them is Fingerprint Authentication.

So, in this blog, we will learn how to use Fingerprint authentication in our Android applications. Also, no two persons can have the same Fingerprint, so, we need not worry about authenticity. But on the other end, if we are using Fingerprint for Authentication, then there is no need to remember password. Also, if you forgot the password or username then you have to recover it by going through a series of steps. Not only you have to enter it manually, but it is also a time-consuming process. Gone are the days when you have to manually enter the username and password for login into some Android application.
