If an app tries to access the microphone while the microphone is already being accessed, it fails.

How can I make two or more apps access the microphone at the same moment?

Simply you can't. because microphone just like camera is a hardware part of the phone and it's drivers connects to only one source, there is a way to make this work but it will be difficult, by using an app to transfer the audio came from microphone and stream it to another app.

  • But how does the telephone app do calls while a third-party voice recorder can keep recording?

It was possible in earlier versions of Android. And I find the same problem, too. Using the third-party apps seems to fix this problem.

From www.androidpolice.com; Privileged apps have higher priority than ordinary apps. Apps with visible foreground UIs have higher priority than background apps. Apps capturing audio from a privacy-sensitive source have higher priority than apps that are not. Two ordinary apps can never capture audio at the same time. In some situations, a privileged app can share audio input with another app. If two background apps of same priority are capturing audio, the last one started has higher priority.
