Answer 1

Did you try deleting and recreating your AVD? You can manually delete the AVD files by going to the directory they're stored in (in your user's /.android/avd subdirectory).

Just write

adb -e reboot

and be happy with adb))

Answer 3

See emulator-5554 unauthorized for adb devices. On API 29 emulator I run adb devices command and got emulator-5554 unauthorized message. Then I created a new avd device from Google APIs image (in my case Q, x86), not from Google Play.

Answer 4

Enable USB Debugging into your emulator

1. Settings > About Phone > Build number > Tap it 7 times to become developer;
2. Settings > Developer Options > USB Debugging.

That's it enjoy

Answer 5

Go to windows task manager and end process "adb.exe". There might be more than 1 instances of the same process, make sure to end all of them.

Answer 6

on linux or mac the port thats blocked will emulator-id + 1 so 5555 so: sudo lsof -i :5555 will show you the pid of process that are taking the port (should be the second column) so to kill it: sudo lsof -i :5555 | awk '{print $2}' | xargs kill

then adb (fake) devices will no longer show on the list
