That’s interesting. I’ve seen the stackoverflow link you provided. I did try yesterday everything there and it didn’t help. What I just did to fix my issue was:

1. Navigate to the /Users/user\_xxx/.android/avd/Nexus6API22.avd
2. Delete all the locks via: $rm \*.lock
3. Wiped Data via AVD Manager
4. Restart the Emulator
5. Success.

Thanks!
