     * <code>&lt;{@link

     * android.R.styleable#ContentCaptureService content-capture-service}&gt;</code> tag.

     *

     * <p>This is a a sample XML file configuring a ContentCaptureService:

     * <pre> &lt;content-capture-service

     *     android:settingsActivity="foo.bar.SettingsActivity"

     *     . . .

     * /&gt;</pre>

     * <p>Here's an example of how to use it on {@code AndroidManifest.xml}:

     *

     * <pre>

     * <service android:name=".MyContentCaptureService"

     *     android:permission="android.permission.BIND_CONTENT_CAPTURE_SERVICE">

     *   <intent-filter>

     *     <action android:name="android.service.contentcapture.ContentCaptureService" />

     *   </intent-filter>

     *

     *   <meta-data

     *       android:name="android.content_capture"

     *       android:resource="@xml/my_content_capture_service"/>

     * </service>

     * </pre>

     *

     * <p>And then on {@code res/xml/my_content_capture_service.xml}:

     *

     * <pre>

     *   <content-capture-service xmlns:android="http://schemas.android.com/apk/res/android"

     *       android:settingsActivity="my.package.MySettingsActivity">

     *   </content-capture-service>

     * </pre>
