 <h3 id="billing-purchase-type">Choosing a Purchase Type</h3>
 
-<p>An item's purchase type controls how Android Market manages the purchase of the item. There are two purchase types: "managed per user account" and "unmanaged."</p>
-
-<p>Items that are managed per user account can be purchased only once per user account. When an item is managed per user account, Android Market permanently stores the transaction information for each item on a per-user basis. This enables you to query Android Market with the <code>RESTORE_TRANSACTIONS</code> request and restore the state of the items a specific user has purchased.</p>
-
-<p>If a user attempts to purchase a managed item that has already been purchased, Android Market displays an "Item already purchased" error. This occurs during checkout, when Android Market displays the price and description information on the checkout page. When the user dismisses the error message, the checkout page disappears and the user returns to your user interface. As a best practice, your application should prevent the user from seeing this error. The sample application demonstrates how you can do this by keeping track of items that are managed and already purchased and not allowing users to select those items from the list. Your application should do something similar&mdash;either graying out the item or hiding it so that it cannot be selected.</p>
-
-<p>The "manage by user account" purchase type is useful if you are selling items such as game levels or application features. These items are not transient and usually need to be restored whenever a user reinstalls your application, wipes the data on their device, or installs your application on a new device.</p>
-
-<p>Items that are unmanaged do not have their transaction information stored on Android Market, which means you cannot query Android Market to retrieve transaction information for items whose purchase type is listed as unmanaged. You are responsible for managing the transaction information of unmanaged items. Also, unmanaged items can be purchased multiple times as far as Android Market is concerned, so it's also up to you to control how many times an unmanaged item can be purchased.</p>
-
-<p>The "unmanaged" purchase type is useful if you are selling consumable items, such as fuel or magic spells. These items are consumed within your application and are usually purchased multiple times.</p>

 <h2 id="billing-refunds">Handling Refunds</h2>
 
-<p>In-app billing does not allow users to send a refund request to Android Market. Refunds for in-app purchases must be directed to you (the application developer). You can then process the refund through your Google Checkout Merchant account. When you do this, Android Market receives a refund notification from Google Checkout, and Android Market sends a refund message to your application. For more information, see <a href="{@docRoot}guide/market/billing/billing_overview.html#billing-action-notify">Handling IN_APP_NOTIFY messages</a> and <a href="http://www.google.com/support/androidmarket/bin/answer.py?answer=1153485">In-app Billing Pricing</a>.</p>

 <h2 id="billing-testing-setup">Setting Up Test Accounts</h2>
 
-<p>The Android Market publisher site lets you set up one or more test accounts. A test account is a regular Google account that you register on the publisher site as a test account. Test accounts are authorized to make in-app purchases from applications that you have uploaded to the Android Market site but have not yet published.</p>

-<p>You can use any Google account as a test account.

 <h2>Security Best Practices</h2>
 
 <h4>Perform signature verification tasks on a server</h4>
-<p>If practical, you should perform signature verification on a remote server and not on a device. Implementing the verification process on a server makes it difficult for attackers to break the verification process by reverse engineering your .apk file. If you do offload security processing to a remote server, be sure that the device-server handshake is secure.</p>

 <h4>Protect your unlocked content</h4>

   </ul>
-<p>When you deliver content from a remote server or a real-time service, you can store the unlocked content in device memory or store it on the device's SD card. If you store content on an SD card, be sure to encrypt the content and use a device-specific encryption key.</p>

 <h4>Obfuscate your code</h4>
-<p>You should obfuscate your in-app billing code so it is difficult for an attacker to reverse engineer security protocols and other application components. At a minimum, we recommend that you run an  obfuscation tool like <a href="http://developer.android.com/guide/developing/tools/proguard.html">Proguard</a> on your code.</p>
-<p>In addition to running an obfuscation program, we recommend that you use the following techniques to obfuscate your in-app billing code.</p>

 <ul>
   <li>Inline methods into other methods.</li>
   <li>Construct strings on the fly instead of defining them as constants.</li>
   <li>Use Java reflection to call methods.</li>

 <h4>Modify all sample application code</h4>
-<p>The in-app billing sample application is publicly distributed and can be downloaded by anyone, which means it is relatively easy for an attacker to reverse engineer your application if you use the sample code exactly as it is published. The sample application is intended to be used only as an example. If you use any part of the sample application, you must modify it before you publish it or release it as part of a production application.</p>
-<p>In particular, attackers look for known entry points and exit points in an application, so it is important that you modify these parts of your code that are identical to the sample application.</p>

 <h4>Use secure random nonces</h4>
-<p>Nonces must not be predictable or reused. Always use a cryptographically secure random number generator (like {@link java.security.SecureRandom}) when you generate nonces. This can help reduce replay attacks.</p>

 <h4>Take action against trademark and copyright infringement</h4>
-<p>If you see your content being redistributed on Android Market, act quickly and decisively. File a <a href="http://market.android.com/support/bin/answer.py?hl=en&amp;answer=141511">trademark notice of infringement</a> or a <a href="http://www.google.com/android_dmca.html">copyright notice of infringement</a>.</p>

+infringement</a>.</p>
 
 <h4>Implement a revocability scheme for unlocked content</h4>
-<p>If you are using a remote server to deliver or manage content, have your application verify the purchase state of the unlocked content whenever a user accesses the content. This allows you to revoke use when necessary and minimize piracy.</p>

 <h4>Protect your Android Market public key</h4>
-<p>To keep your public key safe from malicious users and hackers, do not embed it in any code as a literal string. Instead, construct the string at runtime from pieces or use bit manipulation (for example, XOR with some other string) to hide the actual key. The key itself is not secret information, but you do not want to make it easy for a hacker or malicious user to replace the public key with another key.</p>

 <h2 id="billing-permission">Updating Your Application's Manifest</h2>
 
-<p>In-app billing relies on the Android Market application, which handles all communication between your application and the Android Market server. To use the Android Market application, your application must request the proper permission. You can do this by adding the <code>com.android.vending.BILLING</code> permission to your AndroidManifest.xml file. If your application does not declare the in-app billing permission, but attempts to send billing requests, Android Market will refuse the requests and respond with a <code>RESULT_DEVELOPER_ERROR</code> response code.</p>

-<p>Android Market In-app Billing is an Android Market service that provides checkout processing for in-app purchases. To use the service, your application sends a billing request for a specific in-app product. The service then handles all of the checkout details for the transaction, including requesting and validating the form of payment and processing the financial transaction. When the checkout process is complete, the service sends your application the purchase details, such as the order number, the order date and time, and the price paid. At no point does your application have to handle any financial transactions; that role is provided by Android Market's in-app billing service.</p>

 <h2 id="billing-arch">In-app Billing Architecture</h2>
 
-<p>In-app billing uses an asynchronous message loop to convey billing requests and billing responses between your application and the Android Market server. In practice, your application never directly communicates with the Android Market server (see figure 1). Instead, your application sends billing requests to the Android Market application over interprocess communication (IPC) and receives purchase responses from the Android Market application in the form of asynchronous broadcast intents. Your application does not manage any network connections between itself and the Android Market server or use any special APIs from the Android platform.</p>
-
-<p>Some in-app billing implementations may also use a private remote server to deliver content or validate transactions, but a remote server is not required to implement in-app billing. A remote server can be useful if you are selling digital content that needs to be delivered to a user's device, such as media files or photos. You might also use a remote server to store users' transaction history or perform various in-app billing security tasks, such as signature verification. Although you can handle all security-related tasks in your application, performing those tasks on a remote server is recommended because it helps make your application less vulnerable to security attacks.</p>

 <p>A typical in-app billing implementation relies on three components:</p>
 <ul>
-  <li>A {@link android.app.Service} (named <code>BillingService</code> in the sample application), which processes purchase messages from the application and sends billing requests to Android Market's in-app billing service.</li>

 <p>You may also want to incorporate two other components to support in-app billing:</p>
 <ul>
-  <li>A response {@link android.os.Handler} (named <code>ResponseHandler</code> in the sample application), which provides application-specific processing of purchase notifications, errors, and other status messages.</li>
-  <li>An observer (named <code>PurchaseObserver</code> in the sample application), which is responsible for sending callbacks to your application so you can update your user interface with purchase information and status.</li>

-<p>In addition to these components, your application must provide a way to store information about users' purchases and some sort of user interface that lets users select items to purchase. You do not need to provide a checkout user interface. When a user initiates an in-app purchase, the Android Market application presents the checkout user interface to your user. When the user completes the checkout process, your application resumes.</p>

 <h2 id="billing-msgs">In-app Billing Messages</h2>
 
-<p>When the user initiates a purchase, your application sends billing messages to Android Market's in-app billing service (named <code>MarketBillingService</code>) using simple IPC method calls. The Android Market application responds to all billing requests synchronously, providing your application with status notifications and other information. The Android Market application also responds to some billing requests asynchronously, providing your application with error messages and detailed transaction information. The following section describes the basic request-response messaging that takes place between your application and the Android Market application.</p>

 <h3 id="billing-request">In-app billing requests</h3>
 
-<p>Your application sends in-app billing requests by invoking a single IPC method (<code>sendBillingRequest()</code>), which is exposed by the <code>MarketBillingService</code> interface. This interface is defined in an <a href="{@docRoot}guide/developing/tools/aidl.html">Android Interface Definition Language</a> file (<code>IMarketBillingService.aidl</code>). You can <a href="{@docRoot}guide/market/billing/billing_integrate.html#billing-download">download</a> this AIDL file with the in-app billing sample application.</p>
-
-<p>The <code>sendBillingRequest()</code> method has a single {@link android.os.Bundle} parameter. The Bundle that you deliver must include several key-value pairs that specify various parameters for the request, such as the type of billing request you are making, the item that is being purchased, and the application that is making the request. For more information about the Bundle keys that are sent with a request, see <a href="{@docRoot}guide/market/billing/billing_reference.html#billing-interface">In-app Billing Service Interface</a>.

 <h2 id="billing-security">Security Controls</h2>
 
-<p>To help ensure the integrity of the transaction information that is sent to your application, Android Market signs the JSON string that is contained in the <code>PURCHASE_STATE_CHANGED</code> broadcast intent. Android Market uses the private key that is associated with your publisher account to create this signature. The publisher site generates an RSA key pair for each publisher account. You can find the public key portion of this key pair on your account's profile page. It is the same public key that is used with Android Market licensing.</p>
-
-<p>When Android Market signs a billing response, it includes the signed JSON string (unencrypted) and the signature. When your application receives this signed response you can use the public key portion of your RSA key pair to verify the signature. By performing signature verification you can help detect responses that have been tampered with or that have been spoofed. You can perform this signature verification step in your application; however, if your application connects to a secure remote server then we recommend that you perform the signature verification on that server.</p>
-
-<p>In-app billing also uses nonces (a random number used once) to help verify the integrity of the purchase information that's returned from Android Market. Your application must generate a nonce and send it with a <code>GET_PURCHASE_INFORMATION</code> request and a <code>RESTORE_TRANSACTIONS</code> request. When Android Market receives the request, it adds the nonce to the JSON string that contains the transaction information. The JSON string is then signed and returned to your application. When your application receives the JSON string, you need to verify the nonce as well as the signature of the JSON string.</p>

-<p>When you use Android Market's in-app billing service to sell an item, Android Market handles all checkout details so your application never has to directly process any financial transactions. Android Market uses the same checkout service that is used for application purchases, so your users experience a consistent and familiar purchase flow (see figure 1). Also, the transaction fee for in-app purchases is the same as the transaction fee for application purchases (30%).</p>

-<p>Any application that you publish through Android Market can implement in-app billing. No special account or registration is required other than an Android Market publisher account and a Google Checkout Merchant account. Also, because the service uses no dedicated framework APIs, you can add in-app billing to any application that uses a minimum API level of 4 or higher.</p>

-<p>To help you integrate in-app billing into your application, the Android SDK provides a sample application that demonstrates a simple implementation of in-app billing. The sample application contains examples of billing-related classes you can use to implement in-app billing in your application. It also contains examples of the database, user interface, and business logic you might use to implement in-app billing.</p>
