Attempt to invoke virtual method 'double java.lang.Double.doubleValue()' on a null object reference

When trying to discover readers, I'm getting the following error message:

Attempt to invoke virtual method 'double java.lang.Double.doubleValue()' on a null object reference

Following the guidance in the README, here's the code I'm running:

            StripeTerminal.discoverReaders(
              StripeTerminal.DeviceTypeChipper2X,
              StripeTerminal.DiscoveryMethodBluetoothProximity
            );

Any ideas on how to get past this?

I have only been briefly playing around with the library, this issue might help #23 @EthanCents . It seems discoverReaders takes a third parameter, 0 or 1 to show 0 = not simulated, 1 = simulated
