You 189 usually send this request when your application first starts up. This request is useful if you 190 want to enable or disable certain UI features that are relevant only to In-app Billing.</p> 191 </li> 192 <li><code>REQUEST_PURCHASE</code> 193 <p>This request sends a purchase message to the Google Play application and is the foundation 194 of In-app Billing. You send this request when a user indicates that he or she wants to purchase 195 an item in your application. Google Play then handles the financial transaction by displaying 196 the checkout user interface.</p> 197 </li> 198 <li><code>GET_PURCHASE_INFORMATION</code> 199 <p>This request retrieves the details of a purchase state change. A purchase state change can 200 occur when a purchase request is billed successfully or when a user cancels a transaction during 201 checkout. It can also occur when a previous purchase is refunded. Google Play notifies your 202 application when a purchase changes state, so you only need to send this request when there is 203 transaction information to retrieve.</p> 204 </li> 205 <li><code>CONFIRM_NOTIFICATIONS</code> 206 <p>This request acknowledges that your application received the details of a purchase state 207 change.

You should send this message only when you need to 215 retrieve a user's transaction status, which is usually only when your application is reinstalled 216 or installed for the first time on a device.</p> 217 </li> 218</ul> 219 220<p>Every In-app Billing request generates a synchronous response.

These broadcast intents inform your application about In-app Billing actions 282that have occurred. Your application must implement a {@link android.content.BroadcastReceiver} to 283receive these broadcast intents, such as the <code>BillingReceiver</code> that's shown in the in-app 284billing <a href="{@docRoot}google/play/billing/v2/billing_integrate.html#billing-download">sample 285application</a>.</p> 286 287<h4>com.android.vending.billing.RESPONSE_CODE</h4> 288 289<p>This broadcast intent contains a Google Play response code, and is sent after you make an 290In-app Billing request. A server response code can indicate that a billing request was successfully 291sent to Google Play or it can indicate that some error occurred during a billing request. This 292intent is not used to report any purchase state changes (such as refund or purchase information). 293For more information about the response codes that are sent with this response, see <a 294href="#billing-codes">Google Play Response Codes for In-app Billing</a>.

This response contains one or more notification IDs. Each notification ID 311corresponds to a specific server-side message, and each messages contains information about one or 312more transactions. After your application receives an <code>IN_APP_NOTIFY</code> broadcast intent, 313you send a <code>GET_PURCHASE_INFORMATION</code> request with the notification IDs to retrieve the 314message details.

The 329transaction information is contained in a JSON string. The JSON string is signed and the signature 330is sent to your application along with the JSON string (unencrypted).
