title: How to generate ephemeral_keys in Stripe payment Android
body: <p>I am implementing Stripe payment for my android application.
  I download Stripe payment SDK example but I getting one error "<a href="https://hidden-beach-12345.herokuapp.com/ephemeral_keys" rel="nofollow noreferrer">https://hidden-beach-12345.herokuapp.com/ephemeral_keys</a>" every time.
  I don't know how can I generate an ephemeral key from stripe?</p>
