I want to know the FM Radio signal strength in Android. For this I have to interact with hardware or not? Or is there any API which can directly give me the value of signal strength?

FM radio is available in some phones. Anyways you must have an FM tuner (radio) built-in.

Yes, of course you will have to as it has not been brought into the stack.
is there any API which can directly give me the value of signal strength?
I think, NO.
Maybe you will have to write your own jni, and java source and add it to the stack, if you need one.
