Failure [INSTALL_FAILED_DEXOPT] with Android Studio 0.8.1

Question

When I try to debug my app I am getting this error: Failure [INSTALL_FAILED_DEXOPT]

I am using Android Studio 0.8.1. This is the log when I am trying to install and debug the app.

Installing <mypackage>
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/<mypackage>"
pkg: /data/local/tmp/<mypackage>
Failure [INSTALL_FAILED_DEXOPT]

Now it happens with all apps in my IDE, with all my real and virtual devices.
