I\'ve installed the latest Fabric plugin for Android Studio and it run fine for a while. Just after updating to Android Studio 1.1.0 I got this in event log:
I had the exact same problem, I'm using the latest AndroidStudio all the time and for some reason the fabric plugin was not working. The way I solved the issue is by not using Fabric Android Studio plugin and instead downloading the Fabric IntelliJ Plugin.
To make sure it works you should uninstall any fabric plugin you currently have and restart the Android Studio. Then Launch the Android Studio and install the downloaded FabricIntelliJPlugin.zip
file as plugin and apply the changes. (don't forget to restart again)
Hope this will help.
