How it should be added to AndroidManifest.xml file?

Just adding via <service android:name="com.kieronquinn.app.controltest.ControlTile"/> does not work. Looks like there should be some intent-filter.

Found an answer by decompiling Google Home app.

<service android:name="com.google.android.apps.chromecast.app.systemcontrol.HomeControlService" android:permission="android.permission.BIND_CONTROLS" android:exported="true">
  <intent-filter>
    <action android:name="android.service.controls.ControlsProviderService"/>
  </intent-filter>
</service>

Can you please provide a full sample for it on Github? Maybe of the minimal stuff to make a tile on the power menu?

Seems you have a bug on your code. Long pressing the tiles should open some Activity, and you need to add FLAG_ACTIVITY_NEW_TASK to the Intent.

@AndroidDeveloperLB

This was meant to just be a dirty example during the previews and betas, not a full sample project. The code is out of date, launching the activity previously worked as is shown in the video on here which is running this exact code: https://www.xda-developers.com/android-11-quick-control-shortcuts-power-menu/

I don't see long pressing on the tiles. Maybe on 0:19:
https://youtu.be/zhJbzt2Ts5E?t=19

But then it becomes black.
In any case, Tasker app seems to have the same issue, and as a result I also found this crash of the OS when developers don't use it right:
https://issuetracker.google.com/issues/169658959

Yes, that is long press (there's no other interaction there that could launch anything). At that time it launched the activity in that windowed mode, but didn't work correctly, hence the black.

ok

Hi! In your example not working switching between on and off on switch button(background not switching). Do you know how to improve this issue?
