I have one emulator set up locally $ adb devices List of devices attached emulator-5554 device When I do adb connect localhost:5555 I will have 2 devices set up $ adb devices List of devices attached emulator-5554 device localhost:5555 device How is that possible? This is still the same device, right? Available only under two different names. In what situations running adb connect localhost:5555 make sense? I've seen plenty of posts on SO doing that, but what they have emulator available locally?

When to use adb connect with localhost?

I have one emulator set up locally

$ adb devices
List of devices attached
emulator-5554   device

When I do adb connect localhost:5555 I will have 2 devices set up

$ adb devices
List of devices attached
emulator-5554   device
localhost:5555  device

How is that possible? This is still the same device, right? Available only under two different names.
