How can i keep my app running in the background when the screen goes to sleep?

I am creating an app which plays an audio (Player).

How can i keep my app running in the background when the screen goes to sleep? 

Acording to an advice http://puravidaapps.com/countdown.php the videoplayer (1x1) don't prevent an app from a stop. 

A notifier don't allow to switch off an screen - so a phone quickly looses an energy.

You can use WebViewer + html5 Audio tags.

http://www.w3schools.com/html/html5_audio.asp

You can test my Sample app: https://play.google.com/store/apps/details?id=appinventor.ai_peep_prants.Audioboard

It play audio streams and mp3 files.

Audio (mp3) files you find in left upper corner :)

Also it can play backround and also "STOP" audio if call come in.

In mobile device Autoplay is disabled, that mean you need press PLAY when app start.

I don't understand how to use WebViewer + html5 Audio tags in MitAppInvertor. Can you explain?

Thank you for this solution, but it doesn't suit to me, because I want that my app doesn't sleep as I want to have active the GPS and the app should make some work.. not only play audio.

you probably can do it with SL4A http://puravidaapps.com/countdown1.php

You ask: "I am creating an app which plays an audio (Player).

You can try my solution, if screen go sleep, audio still play. If You push "Home" button Audio still play.

Why am I not able to install your app on play store?? It says "This app is incompatible with your device." My phone is Lenevo A369i and android version is 4.2 Jelly Bean.

--

I`m not see Lenovo A369i Google Play supported phone list. There is with similar Lenovo`s A360, A360t, A360e and A366t.

Sorry, I can`t add you phone if google not support this :(

This is great solution. Peep, Installed your app as well, Looks great. 5*****

How did you auto start playing after loading - in your app. 

Is it possible to add external buttons for Play,Pause,volume. 

Do I need to create 1 html file each station or is there way to make list of audio source and somehow modify html file.
