@adhikari-jagdish try this approach: Use dispose() each time when you finish your work with fingerprint.

class SomeClass { private var subscription: Disposable? = null fun encrypt(context: Context, fingerKey: String, pin: String) { subscription = RxFingerprint.encrypt(context, fingerKey, pin) .observeOn(AndroidSchedulers.mainThread()) .subscribe({ result: FingerprintEncryptionResult -> //TODO: add code for onNext }, { exception: Throwable -> //TODO: add code for onError }, { //TODO: add code for onComplete }) } fun onFinish() { subscription?.dispose() } }
