What does "virtual headset plug inserted" of Android emulator mean?

Issue

The official document says:

The Android Emulator doesn't include virtual hardware for the following:

Bluetooth
NFC
SD card insert/eject
Device-attached headphones
USB

However, the emulator has the following settings:

Could anyone shed some light on what these settings mean? The following code returns false for the emulator:

getPackageManager().hasSystemFeature(PackageManager.FEATURE_MICROPHONE)

Solution

I was looking for a way to make Android think I have connected headphones but enabling Virtual headset plug inserted is not enough. Do do that you have to install Lesser AudioSwitch and set input device to headset

Only then getPackageManager().hasSystemFeature(PackageManager.FEATURE_MICROPHONE) will return true
