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 uninstalled the Fabric plugin and installed a newly downloaded 2.2.0 version of the plugin (don't remember) and now it seems the exception is gone.
Note: After the correction from @Dheeraj Bhaskar, I actually did the process for the Fabric plugin - I couldn't find an option to download a Crashlytics plugin.
