NPE with IMarketBillingService sendBillingRequest

[lujop]

I have got some stacktraces reported by ACRA. They are very occasional and it seems to be more on google's part but I don't know if it will be nice to catch the error, and log it.

Hi,

can you check if this happens when you perform a restore transactions on an already purchased item?

Looks like this bug: http://code.google.com/p/marketbilling/issues/detail?id=25
I fixed it naively in my code (not using Android Billing Library) by returning INVALID_REQUEST:

Bundle request = null;
            Bundle response = null;
            try {
                request = makeRequestBundle("CHECK_BILLING_SUPPORTED");
                response = mService.sendBillingRequest(request);
            } catch (NullPointerException e) {
                return Consts.BILLING_RESPONSE_INVALID_REQUEST_ID;
            }
