@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()
}
}
