Billing API v3 IabHelper NullPointerException

Question

Slightly modify the beginning of the queryPurchases method to look like this:

int queryPurchases(Inventory inv, String itemType) throws JSONException, RemoteException {
        // Query purchases
        //logDebug("Querying owned items, item type: " + itemType);
       //logDebug("Package name: " + mContext.getPackageName());
       boolean verificationFailed = false;
       String continueToken = null;

        do {
//            logDebug("Calling getPurchases with continuation token: " + continueToken);
            if(mDisposed || mService==null) return IABHELPER_UNKNOWN_ERROR;
            Bundle ownedItems = mService.getPurchases(3, mContext.getPackageName(),
                    itemType, continueToken);

Thanks to sebastie for pointing out the cause of this.
