Answer 1

edit 4/15: Catching nullpointer in IabHelper appears to have stopped this problem. I am no longer seeing the exceptions being thrown, I'm going to accept this as an answer.

edit 4/04: A little bit of a deeper dive. There are try catch blocks that handle RemoteExceptions and JSONExceptions for the queryPurchases method, but no NullPointerException handling. What I am going to try is include NullPointer Exception handling so IabHelper looks like this when trying to querySkuDetails:

    catch (NullPointerException e) {
        throw new IabException(IABHELPER_UNKNOWN_ERROR, "NullPointer while refreshing inventory.", e);
    }

I just filed a bug on this:

Change

        if (querySkuDetails) {
            r = querySkuDetails(ITEM_TYPE_INAPP, inv, moreItemSkus);
            if (r != BILLING_RESPONSE_RESULT_OK) {
                throw new IabException(r, "Error refreshing inventory (querying prices of items).");
            }
        }

to

        if (querySkuDetails) {
            try {
                r = querySkuDetails(ITEM_TYPE_INAPP, inv, moreItemSkus);
                if (r != BILLING_RESPONSE_RESULT_OK) {
                    throw new IabException(r, "Error refreshing inventory (querying prices of items).");
                }
            } catch (NullPointerException e) {
                throw new IabException(IABHELPER_UNKNOWN_ERROR, "NPE while refreshing inventory.", e);
            }
        }

Change

            if (querySkuDetails) {
                r = querySkuDetails(ITEM_TYPE_SUBS, inv, moreSubsSkus);
                if (r != BILLING_RESPONSE_RESULT_OK) {
                    throw new IabException(r, "Error refreshing inventory (querying prices of subscriptions).");
                }
            }

to

            if (querySkuDetails) {
                try {
                    r = querySkuDetails(ITEM_TYPE_SUBS, inv, moreSubsSkus);

                    }
