How to query (price) information for multiple in-app products at once?

Question

In Android in app billing is it possible to somehow query (price) information for all products using one query? Optimally you could pass in the product IDs and it would return i

Answer 1

It is possible now with Billing API v3. You can get information with getSkuDetails() method. Example is here.

ArrayList skuList = new ArrayList();
skuList.add("premiumUpgrade"); 
skuList.add("gas");
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("ITEM_ID_LIST", skuList);

Bundle skuDetails = mService.getSkuDetails(3, getPackageName(), "inapp", querySkus);

int response = skuDetails.getInt("RESPONSE_CODE");
if (response == 0) {
    ArrayList responseList = skuDetails.getStringArrayList("DETAILS_LIST");

    for (String thisResponse : responseList) {
        JSONObject object = new JSONObject(thisResponse);
        String sku = object.getString("productId");
        String price = object.getString("price");
        if (sku.equals("premiumUpgrade")) {
            mPremiumUpgradePrice = price;
        } else if (sku.equals("gas")) { 
            mGasPrice = price;
        }
    }
}
