Android Question FM radio call

[AndreyPozdnyakov]

Hello!
I need to make it possible for my application to listen to an arbitrary FM radio channel in the background.

Erel wrote in 2011: "There is no API available for the FM radio. It is not part of the OS."

What has changed since then?
Can you provide a link to an example of calling the FM radio from your own program?

Do you want to stream a radio channel from the internet? If so maybe start here with a great example of how to do it in B4J

 

[DonManfred]

of how to do it in B4J

But he is asking about B4A and he wrote "in background". B4J does not apply with this requirements.

as far as I know, not all devices have the hardware FM chip required.
sometimes, even the same phone model may have versions with or without FM-chip (for instance depending if it is an Exynos model or a snapdragon model).

There are some Java APIs around which you could wrap for B4A (or perhaps use with JavaqObject) but they don't support all models;
for instance: https://nabpilot.org/prototype-software-portal/fm-radio-sdk/supported-devices/
