33<h2 id="billing-codes">Server Response Codes</h2>
34<p>The following table lists all of the server response codes that are sent from Google Play to your application. Google Play sends the response code synchronously as an integer mapped to the {@code RESPONSE_CODE} key in the response {@code Bundle}. Your application must handle all of these response codes.</p>

87<p>The In-app Billing Version 3 API is defined in the {@code IInAppBillingService.aidl} file, which is included with the Version 3 <a href="{@docRoot}training/in-app-billing/preparing-iab-app.html#GetSample">sample application</a>.</p>

89<h3 id="getSkuDetails">The getSkuDetails() method</h3>
90<p>This method returns product details for a list of product IDs. In the response {@code Bundle} sent by Google Play, the query results are stored in a String {@code ArrayList} mapped to the {@code DETAILS_LIST} key. Each String in the details list contains product details for a single product in JSON format. The fields in the JSON string with the product details are summarized in table 2.</p>

123<p>This method returns a response code integer mapped to the {@code RESPONSE_CODE} key, and a {@code PendingIntent} to launch the puchase flow for the in-app item mapped to the {@code BUY_INTENT} key. When it receives the {@code PendingIntent}, Google Play sends a response {@code Intent} with the data for that purchase order.  The data that is returned in the response {@code Intent} is summarized in table 3.</p>
