<p>Starting with Qt 5.7, you can create Android services using Qt. A service is a component that runs in background, so, it has no user interface. It is useful to perform long-term operations such as logging GPS, waiting for social media notifications, and so on. A service will continue to run even if the application that started it exits.</p>
<p>To create a service, do the following steps:</p>
<ol class="1" type="1"><li>Uncomment the service part of your <code>AndroidManifest.xml</code>.</li>
<li>Make sure the <code>service</code> tag contains an <code>android:process=":some_name"</code> attribute. It is needed to force the <code>service</code> to run in a separate process than the <code>activity</code>.</li>
<li>If you're using the same application (.so file) for activity and also for service, you need to use <code>android.app.arguments</code> <code>meta-data</code> to pass some arguments to your <code>main</code> function in order to know which one is which.</li>
<li>To enable background running, uncomment <code>android.app.background_running</code> <code>meta-data</code> and set it to true (<code>android:value="true"</code> ).</li>
</ol>
<p>Qt loads the <code>.so</code> file defined in <code>android.app.lib_name</code> <code>meta-data</code>, and calls the <code>main</code> function with all the arguments set in <code>android.app.arguments</code> <code>meta-data</code>.</p>
<p>See <a href="http://developer.android.com/guide/components/services.html">Android Services</a> documentation for more information.</p>
