Android FM Signal Strength

Question

I want to know the signal strength of the FM radio in Android. To do this, do I need to interact with the equipment or not? Or is there any API that can directly give me a signal strength value?

Answer 1

FM radio is available on some phones. In any case, you should have a built-in FM tuner (radio).

To do this, do I need to interact with hardware or not?

Yes, of course, you have to, because it was not pushed onto the stack.

is there any API that can directly give me a signal strength value?

I think no.

You may need to write your own jni and java source and add it to the stack if you need it.
