Can we detect which android application is using the microphone?

问题

Hello everyone i am new to android ndk and want to find two things:

1. Can we detect whether the microphone is on or not?
2. Can we detect which application is using the microphone?

It would be good if anyone knows any idea how to do above through C or through android sdk.

回答1:

1.

AudioManager am =  Context.getSystemService(Context.AUDIO_SERVICE)
am.isMicrophoneMute()

But I don't know how to do it using NDK (and no one seems to know).

AudioManager documentation

2.

No you can't. And that is a security decision. As @AndiJay said, malicious programs could then be used.
