Android studio: emulator is running but not showing up in Run App "choose a running device"

Probably the project you are running is not compatible (API version/Hardware requirements) with the emulator settings. Check in your build.gradle file if the targetSDK and minimumSdk version is lower or equal to the sdk version of your Emulator.

You should also uncheck Tools > Android > Enable ADB Integration

If your case is different then restart your Android Studio and run the emulator again.

This thread helped me to solve my problem, in particular this answer:

• In Android Studio go to Menu -> Tools
• Android
• Uncheck Enable ADB Integration

For anyone else having the issue - none of the answers provided worked for me.

My case may be different to others but I had Android Studio installed first which installs the SDK by default to: C:\Users\[user]\AppData\Local\Android\sdk. We then decided to use Xamarin for our projects, so Xamarin was installed and installed an additional SDK by default, located here: C:\Program Files (x86)\Android\android-sdk.

Changing Xamarin to match the same SDK path worked for me which I did in the registry (although through the VS settings I'd guess it's the same):

\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Android SDK Tools\Path

Change the path to match the Android Studio SDK path, close everything, start the VS Emulator, run Android Studio, ensure ADB integration is off and try. It worked for me.
