<p>A TV application that plays live TV content is required for Android TV devices.
A reference TV application (<a href="https://play.google.com/store/apps/details?id=com.google.android.tv">Live TV</a>) is provided alongside the Android platform, which can be used as-is,
customized, extended, or replaced. The <a href="https://android.googlesource.com/platform/packages/apps/TV/">source code</a> is available in the Android Open Source Project.</p>
<p>This article summarizes how to get started with building a system TV App based
on Live TV on your Android television device and covers a couple of ways
to customize the app. (You may extend your TV application to implement device
manufacturer or country-specific features, however this is not in the scope of
the reference TV App.)</p>
<h2 id=dependencies>Dependencies</h2>
<p>The TV application is a component of the <a href="{@docRoot}devices/tv/">TV Input Framework</a> (TIF) and cannot be used independently of the other components. This means
that only devices with TIF will be able to run the <a href="https://play.google.com/store/apps/details?id=com.google.android.tv">Live TV</a> application.</p>
<p>The Live TV application depends on Android APIs. Different branches have
different dependencies on API levels:</p>
<p class="table-caption" id="table-1">
<strong>Table 1.</strong> Live TV branches.</p>
<table>
<tr>
<th>Branch</th>
<th>API level</th>
</tr>
<tr>
<td><a href="https://android.googlesource.com/platform/packages/apps/TV/+/android-live-tv">android-live-tv</a></td>
<td>23 (Android 6.0)</td>
</tr>
<tr>
<td><a href="https://android.googlesource.com/platform/packages/apps/TV/+/android-live-tv-l-mr1">android-live-tv-l-mr1</a></td>
<td>22 (Android 5.1)</td>
</tr>
</table>
<p>There is no runtime dependency on the API level as the code is
retro-compatible. The same APK can be used for devices with Android 5.1 and 6.0
as runtime checks will enable/disable features with dependencies on Android 6.0
APIs.</p>
<h2 id=get_the_source>Get the source</h2>
<p>To get started, select which version of Live TV youd like from Git. The
instructions below are for the current version of Live TV, but you can
easily select an earlier version by appending the version name to the end of
<code>android-live-tv</code> as seen in the table above.</p>
<pre>
$ mkdir android-live-tv && cd android-live-tv
$ repo init -u <a href="https://android.googlesource.com/platform/manifest">https://android.googlesource.com/platform/manifest</a> -b android-live-tv
$ repo sync -j8 -c
</pre>
<h2 id=build>Build</h2>
<p>To build the Live TV code, run:</p>
<pre>
$ . build/envsetup.sh
$ tapas LiveTv x86
$ make LiveTv
</pre>
<h2 id=push>Push</h2>
<p>To push Live TV to your test device:</p>
<pre>
$ adb install -r -d $OUT/system/priv-app/LiveTv/LiveTv.apk
</pre>
<p>If the developer wants the LIVE TV app to have system permissions, the first time it
is installed it needs to be pushed to /system/priv-app with:</p>
<pre>adb push $OUT/system/priv-app/LiveTv/LiveTv.apk /system/priv-app/LiveTv/</pre>
<h2 id=test>Test</h2>
<p>Once Live TV is on your device, you should test that it is properly
integrated. In addition to running the <a href="{@docRoot}compatibility/cts/index.html">Compatibility test suite</a> and the <a href="http://source.android.com/compatibility/cts/verifier.html">CTS Verifier tests</a> for the TV app, you can use these tests below:</p>
<h3 id=unit_tests>Unit tests</h3>
<p>There are unit and functional tests for the Live TV app. You must have a
device (or emulator) connected to run the tests.</p>
<pre>
$ adb shell logcat -c
m LiveTv TVTestInput TVUnitTests -j20 &&\
adb install -r -d $OUT/system/priv-app/LiveTv/LiveTv.apk &&\
adb install -r -d $OUT/system/app/TVTestInput/TVTestInput.apk && \

</pre>

<pre>
$ adb shell logcat -c

<h3 id=jank_tests>Jank Tests</h3>
<p>The Jank tests look for dropped frames and delays in rendering.</p>
<pre>
$ adb shell logcat -c

adb install -r -d $OUT/system/priv-app/LiveTv/LiveTv.apk &&\
adb install -r -d $OUT/system/app/TVTestInput/TVTestInput.apk &&\

adb shell pm clear <a href="http://com.google.android.tv/">com.google.android.tv</a> &&\
echo "Creating a lot of channels and EPG data, this may take a while" &&\
