<p>This is a demo application highlighting how to use the KeyChain APIs introduced in API Level 14.</p>
|
|
|
|
<p>The source code for this demo app shows how to install a PKCS12 key chain stored in the assets folder,
|
|
grant permission to the app to use the installed key chain and finally display the certificate and
|
|
private key info. The app also has a simple implementation of a web server listening to requests
|
|
at an SSL socket using the same certificate in the key chain.
|
|
</p>
|
|
|
|
<p>The application includes the following key classes:</p>
|
|
<ul>
|
|
<li><a href="src/com/example/android/keychain/KeyChainDemoActivity.html"><code>KeyChainDemoActivity</code></a>
|
|
— the main <code>Activity</code> that is used to install the key chain and start/stop
|
|
the web server. </li>
|
|
<li><a href="src/com/example/android/keychain/SecureWebServer.html"><code>SecureWebServer</code></a>
|
|
— a single thread web server listening at port 8080 for <code>https://localhost:8080</code> request</li>
|
|
<li><a href="src/com/example/android/keychain/SecureWebServerService.html"><code>SecureWebServerService</code></a>
|
|
— a <code>Service</code> that runs the web server in the foreground.</li>
|
|
</ul>
|
|
|
|
<p>If you are developing an application that uses the KeyChain APIs,
|
|
remember that the feature is supported only on Android 4.0 (API level 14) and
|
|
higher versions of the platform. To ensure that your application can only be
|
|
installed on devices that are running Android 4.0, remember to add the
|
|
following to the application's manifest:</p>
|
|
<ul>
|
|
<li><code><uses-sdk android:minSdkVersion="14" /></code>, which
|
|
indicates to the Android platform that your application requires
|
|
Android 4.0 or higher. For more information, see <a
|
|
href="../../../guide/appendix/api-levels.html">API Levels</a> and the
|
|
documentation for the <a
|
|
href="../../../guide/topics/manifest/uses-sdk-element.html"><code><uses-sdk></code></a>
|
|
element.</li>
|
|
</ul>
|
|
|
|
<p>Note: Due to browser cache, you need to restart the browser completely before it can recognize
|
|
any keystore updates. The easiest way to do this is to dismiss the app in the Recent Apps list.
