Alt-tab-macos: Android emulator is missing from the applications list

[Stokestack]

Describe the bug
I'm programming in Android Studio and running my app in the emulator. Although the emulator is its own application and shows up in Apple's Command-Tab list, it doesn't show up in Alt-Tab.

Screenshots / video

Steps to reproduce the bug

1. Download and install Android Studio:
2. Install Java 8 runtime (I think; just going from memory here): https://www.java.com/en/download/
3. Download a sample project from their training course:
4. Build and run the project in the emulator. I think the emulator is automatically installed.
5. Try to Alt-Tab between Android Studio & the emulator

There is something funky about the emulator. It frequently doesn't quit when told to, and it often prevents shutdowns.

Hi @Stokestack! Thanks for sharing this issue!

I already worked on this issue in the past in #376. I encourage you to check my comments there. I explain how the Android Emulator is a very unique app on the mac. It has no bundleIdentifier for example. It is a very weird app. If you want to keep it in your Dock for example, you will see a messy behavior with the icon changing when you close it.

I thought my workaround was working since the user confirmed it does. I guess you may be running a different version or some other variation that breaks my workaround.

Could you please run this command in your Terminal, and share the result?

ps -ef | grep qemu

Also could you please share which version of Android Studio, and which version of the emulator you're running?

This looks like a difficult issue to address. I have no idea how MacOS themselves addresses this issue haha.

Thanks for the reply. Here you go:

Android Studio 4.0. It's not a huge deal; as we've both noted, there's plenty funky about this app and even the OS can't manage it normally. It's probably not worth further effort, when we have that all-important "windowless apps" problem to solve! 🙂

I could reproduce locally, and found the root cause 🎉

This is a regression introduced by the new blacklist feature a few days ago. I'll release a fix very soon.

Hey thanks for taking the time! This will make debugging easier.
