meta data must include a setup interface that describes the TV input's initial configuration and

channel scan. Also, the service meta data may (optionally) describe a settings activity for users to

modify the TV input's behavior. The service meta data file is located in the XML resources directory

channel scan. The service meta data file is located in the XML resources directory

for your application and must match the name of the resource in the manifest. Using the example

manifest entries above, you would create an XML file in the location

<code>res/xml/sample_tv_input.xml</code>, with the following contents:</p>

<pre>

<tv-input xmlns:android="http://schemas.android.com/apk/res/android"

  <!-- Required: activity for setting up the input -->

  android:setupActivity="com.example.sampletvinput.SampleTvInputSetupActivity"

  <!-- Optional: activity for controlling the settings -->

  android:settingsActivity="com.example.sampletvinput.SampleTvInputSettingsActivity" />

  android:setupActivity="com.example.sampletvinput.SampleTvInputSetupActivity" />

<p>The system TV app works with the setup activity you define for your TV input. The

setup activity is required and must provide at least one channel record for the system database. The

system TV app will invoke the setup activity when it cannot find a channel for the TV input.

<p>The setup activity describes to the system TV app the channels made available through the TV

input, as demonstrated in the next lesson, <a href="{@docRoot}training/tv/tif/channel.html">Creating

and Updating Channel Data</a>.</p>

<p>The settings activity is optional. You can define a settings activity to turn on parental

controls, enable closed captions, set the display attributes, and so forth.</p>
