Question

I am using the IabHelper utility classes, as recommended by Google\'s tutorial, and I\'m being hit hard by this error. Apparently IabHelper can not

A little-modified version of NadtheVlad's answer that works like charm

private void makePurchase() {

    if (mHelper != null) {
        try {
            mHelper.launchPurchaseFlow(getActivity(), ITEM_SKU, 10001, mPurchaseFinishedListener, "");
        }
        catch(IllegalStateException ex){
            mHelper.flagEndAsync();
            makePurchase();
        }
    }
}

The logic is simple, just put the launchPurchaseFlow() thing in a method and use recursion in the catch block. You still need to make flagEndAsync() public from the IabHelper class.
