I have create a web radio, but my issue is:

1) when I change to another screen (screen2 for example) it pause the radio
2) when the screensaver activate it pause again

I am not sure how I can fix them

Taifun has several suggestions to keep the device from 'sleeping'

They might help with issue 2, regarding issue 1  the simple solution is to code the app using a single screen.

Sleeping is an issue with AI2.  If you want to encourage the development team to work on this issue, star this issue:

Visit here frequently, someone may have a solution other than work-arounds.

meanwhile you can use Peep's solution, which uses HTML5 audio tags, see here How can i keep my app running in the background when the screen goes to sleep?

Here is the code how I create a live streaming (mp3) radio.

The sleep issue I fix it with timer. For the other issue I have tried almost everything and still nothing.

you other issue is simple to fix: use only 1 screen instead of multiple screens

to simulate multiple screens, use vertical screen arrangements and set them to visible true/false as needed

Tnx for you help! But i want an FM radio, that on every channel can.

Like https://play.google.com/store/apps/details?id=com.tunewiki.fmplayer.android (fm player)

Is that possible?

Yes. But...

Although you could fix 88.7 to be 'The Rock'. That number represents a different channel in different cities since radio signals are limited in range - so using a number scheme does not seem to apply unless your app allows the user to select a city first.

Also, why ask the user to scroll to a number on a dial when they could just pick the station by name or description from a list?

See > this < demo.
