FingerprintLibrary

Add jitpack in project gradle

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        maven { url "https://jitpack.io" }
    }
}

then import library in module gradle.

implementation 'com.github.kuffs:FingerprintLibrary:0.1.1'

Check fingerprint (No UI)

Api api=Api.getApi(context, alias); 

api.startListening(value, new Api.DecryptedListener() {
            @Override
            public void onDecrypted(String value) {

            }

            @Override
            public void onDecryptError(String error) {

            }

            @Override
            public void onAuthenticationFailed() {

            }

            @Override
            public void onKeyInvalidated() {

            }
        });

encrypt a string value

String encrypted = api.encryptString("Encrypt me");

Check fingerprint (With UI)

 AuthenticationDialog.showDialog(context, alias, valuetoDecrypt);

and implement Api.Callback in the calling Activity.

@Override
public void onAuthenticated(String decryptedValue) {

}

@Override
public void onError(String message) {
}

@Override
public void onAuthenticationFailed() {
}

@Override
public void onKeyInvalidated() {
}
