How is a Always on Display for Android coded? - android-studio

My smartphone (Samsung A21s) doesn't supoort the AOD of Samsung. So i tested several apps from the Play store. But I want an app,so i decided to code my own app, which allows me to choose my own background. I want to use the pictures from the gallery. I also want a music control for the AOD. I have a accurate idea of what I want, but I don't know how to code it. Does anybody know, how a AOD is coded? I use Kotlin and I'm working with Android Studio.
Thank you for your help

Tizen send data from wearable to android phone and also from phone to wearable

I need to send some binary files via bluetooth from tizen g2 watch to android phone and then from phone to watch, as I've searched it I can't implement bluetooth in js files as said here so what is the most straightforward way to do it? can we use tizen wearable debug over bluetooth instead? is it applicable in this case?
I'm new to tizen so I feel confused and I really appreciate any advice about this problem.
You can develop companion app using Samsung Accessory Protocol(SAP) in this scenario. Please go through this link to know more. If you are trying to develop the tizen part in web, then have a look in the File Transfer sample of web section. There're separate applications for sending and receiving files from tizen to android and vice versa. You can combine those to implement the bidirectional communication.

UWP Windows 10 JS - background audio work when compile directly to my device, but not when opened from store

Let describe my issue:
I have developed JS app for Windows 10. It works on desktop- background audio, title, album cover- all stuff i need. In VisualStudio- when i deploy app to Mobile Emulator (10.10586)- still- background audio works even if app is gone.
If i deploy my app through Visual Studio to my Mobile Device- everything works great (when it is run/deployed from visual studio). BUT (notice that) - if i open that compile app again from my device (later, i exit visual studio or just close the solution)- backrgound audio: didnt work.
Hope i describe it well- i deploy app, which work great when compile it first time, but lately... didnt.
So, i can provide my code if someone need to check out, but i think is something with platform... and i am not sure how to fix that and how to get help with that :/
Thank you!
After research i made... there is no chance to build and complete that only with javascript. For now... after Anniversary update (2016, August) there is a chance- Microsoft employee confirms that will be possible and we can explorer that with this example they provide: https://github.com/Microsoft/Windows-universal-samples/tree/dev/Samples/BackgroundMediaPlayback ... so... will wait to see :)

Testing windows 10 Universal Application on XBOX One

Is it currently possible to test a UWP application on my own XBOX (not publish, just test on my own personal XBOX One console)?
Based on MS's faq: http://www.xbox.com/en-US/developers/ID...
"For developers working on Universal Windows Apps, you’ll be able to test your games on a retail Xbox One sometime after the second half of 2015"
However I can not find any good details explaining the process for testing/sideloading applications on an XBOX One. Any insight would be greatly appreciated.
You can now
Good news, you are ready to go today. Here are a number of links to get you started and sideloading:
Things to Know: https://news.xbox.com/2016/03/30/xbox-at-build-2016/
Xbox One Dev Mode Activation: http://support.xbox.com/en-US/xbox-one/apps/developer-mode-activation-app-faq
UWP on Xbox One: https://msdn.microsoft.com/en-us/windows/uwp/xbox-apps/index
Getting Started: https://msdn.microsoft.com/en-us/windows/uwp/xbox-apps/getting-started
and finally, a video on how to do this.
Not yet, but soon!
No, it is not possible to deploy a UWP app to an Xbox One yet (early 2016). Late 2015 was mentioned, but like many things, the release has been pushed back.
The best advice I can give is to wait for Build 2016 where it's expected we'll be given an update on the situation.
Prepare for Xbox One
In the meantime, as a developer, you can prepare your UWP apps for Xbox One by following some basic rules...
Make sure your UWP app works well at 1080p. If your PC monitor is a different resolution, use the simulator to test
As Xbox users use an Xbox controller (or voice or Kinect gestures) to navigate, make to test your app for proper keyboard support - as well as touch and mouse for phone/tablet and desktop users
Pay attention to current apps already on Xbox, those built-in and from the Store. Most apps on PC and phone simply won't suit or be useful on the Xbox. Consuming media (video, music, images) or small pieces of content is ideal.
