34<p>Before you start adding license verification to your application, you need to set up your Google
35Play publishing account, your development environment, and test accounts required to verify
36your implementation.</p>
37
38
39<h2 id="account">Setting Up a Publisher Account</h2>
40
41<p>If you don't already have a publisher account for Google Play, you need to register for one
42using your Google account and agree to the terms of service on the Google Play publisher site:</p>
43
44<p style="margin-left:2em;"><a
45href="http://play.google.com/apps/publish">http://play.google.com/apps/publish</a>
46</p>
47
48<p>For more information, see <a
49href="{@docRoot}distribute/googleplay/publish/register.html">Get Started with Publishing</a>.</p>
50
51<p>If you already have a publisher account on Google Play, use your existing
52account to set up licensing.</p>
53
54<p>Using your publisher account on Google Play, you can:</p>
55
56<ul>
57<li>Obtain a public key for licensing</li>
58<li>Debug and test an application's licensing implementation, prior to
59publishing the application</li>
60<li>Publish the applications to which you have added licensing support</li>
61</ul>
62
63<h4>Administrative settings for licensing</h4>
64
65<p>You can manage several
66administrative controls for Google Play licensing on the publisher site. The controls are available
67in the Edit Profile page, in the "Licensing" panel, shown in figure 1. The controls
68let you: </p>
69
70<ul>
71<li>Set up multiple "test accounts," identified by email address. The licensing
72server allows users signed in to test accounts on a device or emulator to send
73license checks and receive static test responses.</li>
74<li>Obtain the account's public key for licensing. When you are implementing
75licensing in an application, you must copy the public key string into the
76application.</li>
77<li>Configure static test responses that the server sends, when it receives a
78license check for an application uploaded to the publisher account, from a user
79signed in to the publisher account or a test account.</li>
80</ul>

93<h2 id="dev-setup">Setting Up the Development Environment</h2>
94
95<p>Setting up your environment for licensing involves these tasks:</p>

97<ol>
98<li><a href="#runtime-setup">Setting up the runtime environment</a> for development</li>
99<li><a href="#download-lvl">Downloading the LVL</a> into your SDK </li>

102</ol>
103
104<p>The sections below describe these tasks. When you are done with setup,
105you can begin <a href="{@docRoot}google/play/licensing/adding-licensing.html">Adding
106Licensing to Your App</a>.</p>
107
108<p>To get started, you need to set up a proper runtime environment on which
109you can run, debug, and test your application's implementation of license
110checking and enforcement. </p>
111
112
113<h3 id="runtime-setup">Setting up the runtime environment</h3>
114
115<p>As described earlier, applications check licensing status not by contacting
116the licensing server directly, but by binding to a service provided by the
117Google Play application and initiating a license check request. The Google
118Play service then handles the direct communication with the licensing server
119and finally routes the response back to your application. To debug and test
120licensing in your application, you need to set up a runtime environment that
121includes the necessary Google Play service, so that your application is able
122to send license check requests to the licensing server. </p>
123
124<p>There are two types of runtime environment that you can use: </p>
125
126<ul>
127<li>An Android-powered device that includes the Google Play application, or</li>
128<li>An Android emulator running the Google APIs Add-on, API level 8 (release 2)
129or higher</li>
130</ul>
131
132<h4 id="runtime-device">Running on a device</h4>
133
134<p>To use an Android-powered device for
135debugging and testing licensing, the device must:</p>
136
137<ul>
138<li>Run a compatible version of Android 1.5 or later (API level
1393 or higher) platform, <em>and</em> </li>
140<li>Run a system image on which the Google Play client application
141is preinstalled. </li>
142</ul>
143
144<p>If Google Play is not preinstalled in the system image, your application won't
145be able to communicate with the Google Play licensing server. </p>
146
147<p>For general information about how to set up a device for use in developing
148Android applications, see <a
149href="{@docRoot}tools/device.html">Using Hardware Devices</a>.</p>
150
151<h4 id="runtime-emulator">Running on an Android emulator</h4>
152
153<p>If you don't have a device available, you can use an Android emulator for debugging and testing
154licensing.</p>
155
156<p>Because the Android platforms provided in the Android SDK <em>do
157not</em> include Google Play, you need to download the Google APIs Add-On
158platform, API level 8 (or higher), from the SDK repository. After downloading
159the add-on, you need to create an AVD configuration that uses that system image.
160</p>
161
162<p>The Google APIs Add-On does not include the full Google Play client.
163However, it does provide: </p>
164
165<ul>
166<li>An Google Play background service that implements the
167<code>ILicensingService</code> remote interface, so that your application can
168send license checks over the network to the licensing server. </li>
169<li>A set of underlying account services that let you add an a Google account on
170the AVD and sign in using your publisher account or test account credentials.
171<p>Signing in using your publisher or test account enables you to debug and test
172your application without having publish it. For more information see <a
173href="#acct-signin">Signing in to an authorized account</a>, below.</p></li>
174</ul>
175
176<p>Several versions of the Google APIs add-on are available through the SDK Manager, but only
177the version for Android 2.2 and higher includes the necessary Google
178Play services.</p>
179
180<p>To set up an emulator for adding licensing to an application, follow
181these steps: </p>
182
183<ol>
184  <li>Launch the Android SDK Manager (available under the Eclipse <strong>Window</strong>
185menu or by executing {@code &lt;sdk>/tools/android sdk}).</li>
186  <li>Select and download <strong>Google APIs</strong> for the Android version you'd like to target
187(must be Android 2.2 or higher).</li>
188  <li>When the download is complete, open the AVD Manager (available under the Eclipse
189<strong>Window</strong>
190menu or by executing {@code &lt;sdk>/tools/android avd}).</li>
191  <li>Click
192<strong>New</strong> and set the configuration details for the new AVD. </li>
193  <li>In the dialog that appears, assign a descriptive name to the AVD and then
194use the Target menu to choose the <strong>Google APIs</strong> as
195the system image to run on the new AVD. Set the other configuration details as
196needed and then click <strong>Create AVD</strong> to finish. The SDK tools
197create the new AVD configuration, which then appears in the list of available
198Android Virtual Devices.</li>
199</ol>
200
201<p>If you are not familiar with AVDs or how to use them, see <a
202href="{@docRoot}tools/devices/index.html">Managing Virtual Devices</a>.</p>
203
204<h4 id="project-update">Updating your project configuration</h4>
205
206<p>After you set up a runtime environment that meets the requirements described
207above &mdash; either on an actual device or on an emulator &mdash; make sure to
208update your application project or build scripts as needed, so that your compiled
209<code>.apk</code> files that use licensing are deployed into that environment.
210In particular, if you are developing in Eclipse, make sure that you set up a
211Run/Debug Configuration that targets the appropriate device or AVD. </p>
212
213<p>You do not need to make any changes to your application's
214build configuration, provided that the project is already configured to compile
215against a standard Android 1.5 (API level 3) or higher library. For example:
216
217<ul>
218<li>If you have an existing application that is compiled against
219the Android 1.5 library, you do not need to make any changes to your
220build configuration to support licensing. The build target meets the minimum
221requirements for licensing, so you would continue building
222against the same version of the Android platform.</li>
223
224<li>Similarly, if you are building against Android 1.5 (API level 3) but
225are using an emulator running the Google APIs Add-On API 8 as the application's
226runtime environment, there is no need to change your application's build
227configuration. </li>
228</ul>
229
230<p>In general, adding licensing to an application should have no impact
231whatsoever on the application's build configuration.</p>
232
233
234<h3 id="download-lvl">Downloading the LVL</h3>
235
236<p>The License Verification Library (LVL) is a collection of helper classes that
237greatly simplify the work that you need to do to add licensing to your
238application. In all cases, we recommend that you download the LVL and use it as
239the basis for the licensing implementation in your application.</p>
240
241<p>The LVL is available as a downloadable package of the Android SDK. The
242package includes: </p>
243
244<ul>
245<li>The LVL sources, stored inside an Android library project. </li>
246<li>An example application called "sample" that depends on the LVL library
247project. The example illustrates how an application uses the library helper
248classes to check and enforce licensing.</li>
249</ul>
250
251<p>To download the LVL package into your development environment, use the
252Android SDK Manager. Launch the Android SDK Manager and then
253select the <strong>Google Market Licensing</strong> package, as shown in figure 2.
254Accept the terms and click <strong>Install Selected</strong> to begin the download. </p>
255
256<img src="{@docRoot}images/licensing_package.png" alt=""/>
257<p class="img-caption"><strong>Figure 2.</strong> The Licensing package contains the LVL and
258the LVL sample application.</p>
259
260<p>When the download is complete, the Android SDK Manager installs both
261the LVL library project and the example application into these directories: </p>
262
263<p style="margin-left:2em"><code>&lt;<em>sdk</em>&gt;/extras/google/market_licensing/library/</code>
264&nbsp;&nbsp;(the LVL library project)<br />
265<code>&lt;<em>sdk</em>&gt;/extras/google/market_licensing/sample/</code>&nbsp;&nbsp;(the example
266application)</p>
267
268<p>If you aren't familiar with how to download packess into your SDK, see the
269<a href="{@docRoot}sdk/exploring.html">Exploring the SDK</a>
270document. </p>
271
272
273<h3 id="lvl-setup">Setting Up the Licensing Verification Library</h3>
274
275<p>After downloading the LVL to your computer, you need to set it up in your
276development environment, either as an Android library project or by
277copying (or importing) the library sources directly into your existing
278application package. In general, using the LVL as a library project is recommended,
279since it lets you reuse your licensing code across multiple applications and
280maintain it more easily over time. Note that the LVL is not designed to be
281compiled separately and added to an application as a static .jar file. </p>
282
283<h4>Moving the library sources to a new location</h4>
284
285<p>Because you will be customizing the LVL sources to some extent, you should
286make sure to <em>move or copy</em> the library sources (the entire
287directory at <code>&lt;<em>sdk</em>&gt;/market_licensing/library/</code>)
288to a working directory outside of the SDK. You should then use the relocated
289sources as your working set. If you are using a source-code management
290system, add and track the sources that are in the working location rather
291than those in default location in the SDK. </p>
292
293<p>Moving the library sources is important because when you later update the
294Licensing package, the SDK installs the new files to the same location as
295the older files. Moving your working library files to a safe location ensures
296that your work won't be inadvertently overwritten should you download a new
297version of the LVL.</p>
298
299<h4>Creating the LVL as a library project</h4>
300
301<div class="sidebox-wrapper">
302<div class="sidebox">
303<h2>Working with library projects</h2>
304
305<p>The LVL is provided as an Android library project, which means that you can
306share its code and resources across multiple applications. </p>
307
308<p style="margin-top:.5em;">If you aren't familiar with library projects or how
309to use them, see <a href="{@docRoot}tools/projects/index.html#LibraryProjects">
310Managing Projects</a>.
311</p>
312</div>
313</div>
314
315<p>The recommended way of using the LVL is setting it up as a new Android
316<em>library project</em>. A library project is a type of development project
317that holds shared Android source code and resources. Other Android application
318projects can reference the library project and, at build time, include its
319compiled sources in their <code>.apk</code> files. In the context of licensing,
320this means that you can do most of your licensing development once, in a library
321project, then include the library sources in your various application projects.
322In this way, you can easily maintain a uniform implementation of licensing
323across all of your projects and maintain it centrally. </p>
324
325<p>The LVL is provided as a configured library project &mdash; once you have
326downloaded it, you can start using it right away. </p>
327
328<p>If you are working in Eclipse with ADT, you need to add the LVL to your
329workspace as a new development project, in the same way as you would a new
330application project. </p>
331
332<ol>
333<li>Use the New Project Wizard to create a new
334project from existing sources. Select the LVL's <code>library</code> directory
335(the directory containing the library's AndroidManifest.xml file) as the project
336root.</li>
337<li>When you are creating the library project, you can select any application
338name, package, and set other fields as needed. </li>
339<li>For the library's build target, select Android 1.5 (API level 3) or higher.</li>
340</ol>
341
342<p> When created, the project is
343predefined as a library project in its <code>project.properties</code> file, so
344no further configuration is needed. </p>
345
346<p>For more information about how to create an application project or work with
347library projects in Eclipse, see <a
348href="{@docRoot}tools/projects/projects-eclipse.html">Managing Projects from
349Eclipse with ADT</a>.</p>
350
351
352<h4>Copying the LVL sources to your application</h4>
353
354<p>As an alternative to adding the LVL as a library project, you can copy the
355library sources directly into your application. To do so, copy (or import) the
356LVL's <code>library/src/com</code> directory into your application's
357<code>src/</code> directory.</p>
358
359<p>If you add the LVL sources directly to your application, you can skip the
360next section and start working with the library, as described in <a
361href="{@docRoot}google/play/licensing/adding-licensing.html">Adding
362Licensing to Your App</a>.</p>
363
364
365<h3 id="add-library">Including the LVL library project sources in your
366application</h3>
367
368<p>If you want to use the LVL sources as a library project, you need to add a
369reference to the LVL library project in your application project properties. This tells
370build tools to include the LVL library project sources in your application at
371compile time. The process for adding a reference to a library project depends
372on your development environment, as described below.</p>
373
374<p> If you are developing in Eclipse with ADT, you should already have added the
375library project to your workspace, as described in the previous section. If you
376haven't done that already, do it now before continuing. </p>
377
378<p>Next, open the application's project properties window, as shown below.
379Select the "Android" properties group and click <strong>Add</strong>, then
380choose the LVL library project (com_android_vending_licensing) and click
381<strong>OK</strong>. For more information, see
382<a href="{@docRoot}tools/projects/projects-eclipse.html#SettingUpLibraryProject">
383Managing Projects from Eclipse with ADT</a></p>.

387<p class="img-caption"><strong>Figure 3.</strong> If you are
388working in Eclipse with ADT, you can add the LVL library project to your
389application from the application's project properties.</p>
390
391
392<p>If you are developing using the SDK command-line tools, navigate to the
393directory containing your application project and open the
394<code>project.properties</code> file. Add a line to the file that specifies the
395<code>android.library.reference.&lt;n&gt;</code> key and the path to the
396library. For example: </p>
397
398<pre>android.library.reference.1=path/to/library_project</pre>
399
400<p>Alternatively, you can use this command to update the project
401properties, including the reference to the library project:</p>
402
403<pre class="no-pretty-print" style="color:black">android update lib-project
404--target <em>&lt;target_ID&gt;</em> \

433<h2 id="test-env">Setting Up the Testing Environment</h2>
434
435<p>The Google Play publisher site provides configuration tools that let you
436and others test licensing on your application before it is published. As you are
437implementing licensing, you can make use of the publisher site tools to test
438your application's Policy and handling of different licensing responses and
439error conditions.</p>
440
441<p>The main components of the test environment for licensing include: </p>
442
443<ul>
444<li>A "Test response" configuration in your publisher account that lets you
445set the static licensing response returned, when the server processes a
446license check for an application uploaded to the publisher account, from a user
447signed in to the publisher account or a test account.</li>
448<li>An optional set of test accounts that will receive the static test
449response when they check the license of an application that you have uploaded
450(regardless whether the application is published or not).</li>
451<li>A runtime environment for the application that includes the Google Play
452application or Google APIs Add-On, on which the user is signed in to the
453publisher account or one of the test accounts.</li>
454</ul>
455
456<p>Setting up the test environment properly involves:</p>

464<p>The sections below provide more information.</p>
465
466
467<h3 id="test-response">Setting test responses for license checks</h3>
468
469<p>Google Play provides a configuration setting in your publisher account
470that lets you override the normal processing of a license check and return a
471specified static response code. The setting is for testing only and applies
472<em>only</em> to license checks for applications that you have uploaded, made by
473any user signed in to an emulator or device using the credentials of the
474publisher account or a registered test account. For other users, the server
475always processes license checks according to normal rules.  </p>
476
477<p>To set a test response for your account, sign in to your publisher account
478and click "Edit Profile". In the Edit Profile page, locate the Test Response
479menu in the Licensing panel, shown below. You can select from the full set of
480valid server response codes to control the response or condition you want to
481test in your application.</p>
482
483<p>In general, you should make sure to test your application's licensing
484implementation with every response code available in the Test Response menu.
485For a description of the codes, see <a
486href="{@docRoot}google/play/licensing/licensing-reference.html#server-response-codes">Server

492panel of your account's Edit Profile page, showing the Test Accounts field and the
493Test Response menu.</p>
494
495<p>Note that the test response that you configure applies account-wide &mdash;
496that is, it applies not to a single application, but to <em>all</em>
497applications associated with the publisher account. If you are testing multiple
498applications at once, changing the test response will affect all of those
499applications on their next license check (if the user is signed in to
500the emulator or device using the publisher account or a test account).</p>
501
502<p>Before you can successfully receive a test response for a license check,
503you must sign in to the device or emulator on which the application
504is installed, and from which it is querying the server. Specifically, you must
505sign using either your publisher account or one of the test accounts that you
506have set up. For more information about test accounts, see the next section.</p>

514<h3 id="test-acct-setup">Setting up test accounts</h3>
515
516<p>In some cases, you might want to let multiple teams of developers test
517licensing on applications that will ultimately be published through your
518publisher account, but without giving them access to your publisher account's
519sign-in credentials. To meet that need, the Google Play publisher site lets
520you set up one or more optional <em>test accounts</em> &mdash; accounts that are
521authorized to query the licensing server and receive static test responses from
522your publisher account.</p>
523
524<p>Test accounts are standard Google accounts that you register on your
525publisher account, such that they will receive the test response for
526applications that you have uploaded. Developers can then sign in to their
527devices or emulators using the test account credentials and initiate license
528checks from installed applications. When the licensing server receives a license
529check from a user of a test account, it returns the static test response
530configured for the publisher account.  </p>
531
532<p>Necessarily, there are limitations on the access and permissions given to
533users signed in through test accounts, including:</p>
534
535<ul>
536<li>Test account users can query the licensing server only for applications that
537are already uploaded to the publisher account. </li>
538<li>Test account users do not have permission to upload applications to your
539publisher account.</li>
540<li>Test account users do not have permission to set the publisher account's
541static test response.</li>
542</ul>
543
544<p>The table below summarizes the differences in capabilities, between the
545publisher account, a test account, and any other account.</p>

580<h4 id="reg-test-acct">Registering test accounts on the publisher account</h4>
581
582<p>To get started, you need to register each test account in your publisher
583account. As shown in Figure 4, you
584register test accounts in the Licensing panel of your publisher account's Edit
585Profile page. Simply enter the accounts as a comma-delimited list and click
586<strong>Save</strong> to save your profile changes.</p>
587
588<p>You can use any Google account as a test account. If you want to own and
589control the test accounts, you can create the accounts yourself and distribute
590the credentials to your developers or testers.</p>
591
592<h4 id="test-app-upload">Handling application upload and distribution for test
593account users</h4>
594
595<p>As mentioned above, users of test accounts can only receive static test
596responses for applications that are uploaded to the publisher account. Since
597those users do not have permission to upload applications, as the publisher you
598will need to work with those users to collect apps for upload and distribute
599uploaded apps for testing. You can handle collection and distribution in any way
600that is convenient. </p>
601
602<p>Once an application is uploaded and becomes known to the licensing server,
603developers and testers can continue modify the application in their local
604development environment, without having to upload new versions. You only need to
605upload a new version if the local application increments the
606<code>versionCode</code> attribute in the manifest file. </p>
607
608<h4 id="test-key">Distributing your public key to test account users</h4>
609
610<p>The licensing server handles static test responses in the normal way,
611including signing the license response data, adding extras parameters, and so
612on. To support developers who are implementing licensing using test accounts,
613rather than the publisher account, you will need to distribute
614your public key to them. Developers without access to the publisher site do not
615have access to your public key, and without the key they won't be able to
616verify license responses. </p>
617
618<p>Note that if you decide to generate a new licensing key pair for your account
619for some reason, you need to notify all users of test accounts. For
620testers, you can embed the new key in the application package and distribute it
621to users. For developers, you will need to distribute the new key to them
622directly. </p>
623
624
625<h3 id="acct-signin">Signing in to an authorized account in the runtime
626environment</h3>
627
628<p>The licensing service is designed to determine whether a given user is
629licensed to use a given application &mdash; during a license check, the Google
630Play application gathers the user ID from the primary account on the system
631and sends it to the server, together with the package name of the application
632and other information. However, if there is no user information available, the
633license check cannot succeed, so the Google Play application terminates the
634request and returns an error to the application. </p>
635
636<p>During testing, to ensure that your application can successfully query the
637licensing server, you must make sure that you sign in to an account <em>on the
638device or emulator</em> using:</p>
639
640<ul>
641<li>The credentials of a publisher account, or</li>
642<li>The credentials of a test account that is registered with a publisher
643account</li>
644</ul>

649<h2>Signing in to a Google account on an emulator</h2>
650
651<p>If you are testing licensing on an emulator, you need to sign in to a Google
652account on the emulator. If you do not see an option to create a new Google
653account, the problem might be that your AVD is running a standard Android system
654image, rather than the Google APIs Add-On, API 8 (release 2) or higher. </p>

661
662<p>Signing in using a publisher account offers the advantage of letting your
663applications receive static test responses even before the applications are
664uploaded to the publisher site.</p>
665
666<p>If you are part of a larger organization or are working with external groups
667on applications that will be published through your site, you will more likely
668want to distribute test accounts instead, then use those to sign in during
669testing. </p>
670
671<p>To sign in on a device or emulator, follow the steps below. The preferred
672approach is to sign in as the primary account &mdash; however, if there are
673other accounts already in use on the device or emulator, you can create an
674additional account and sign in to it using the publisher or test account
675credentials.  </p>
676
677<ol>
678<li>Open Settings &gt; Accounts &amp; sync</li>
679<li>Select <strong>Add Account</strong> and choose to add a Google account.
680</li>
681<li>Select <strong>Next</strong> and then <strong>Sign in</strong>.</li>
682<li>Enter the username and password of either the publisher account or a test
683account that is registered in the publisher account.</li>
684<li>Select <strong>Sign in</strong>. The system signs you in to the new
685account.</li>
686</ol>
687
688<p>Once you are signed in, you can begin testing licensing in your application
689(if you have completed the LVL integration steps above). When your application
690initiates a license check, it will receive a response containing the static test
691response configured on the publisher account. </p>
692
693<p>Note that, if you are using an emulator, you will need to sign in to the
694publisher account or test account each time you wipe data when restarting the
695emulator.</p>
