Solution- Open task manager and kill qemu-system (Under Android Studio). My emulator used to suddenly disappear but the app still continues to run. Hope this clears out a bit how the command was intended to work And once you have at least one running emulator/device it will return a list with it.
In this directory Go to extra > intel > Hardware_Accelerated_Execution_Manager and run the file named intelhaxm-android.exe So when no emulators are running and no devices are paired tns device will output empty list, since there are no currently running devices.
2) Now go to your SDK directory (C:\users\username\AppData\Local\Android\sdk, generally). 1) Open SDK Manager and Download Intel x86 Emulator Accelerator (HAXM installer) if you haven't.
