I use Android Studio 3.0.1 on Ubuntu 16.04.
Yesterday, Android Studio popped up a message saying that there\'s an update available, and I always click those. It the
i had exactly the same problem, in ubuntu 16.04 and android studio 3.0.1
after a bit googling with this error message:
ADB rejected shell command (getprop): closed
i found a user in the Arch forumn that discussed the error.
an easy solution is: after click on the AVD Manager in AS > click on Edit this AVD with a pencil icon > in Graphics dropdown menu choose Software.
this mode maybe cause to decreasing emulator speed but can be a temporary solution for the problem.
