Intellij IDEA报错：Could not save application settings: java.io.IOException: java.lang.AssertionError:

Question:

　　i have a message saying "Could not save application settings: java.io.IOException: java.lang.AssertionError: Unexpected content storage modification" when running the apps. Anybody have an idea how to fix this?

Answer:

　　I ran into this issue as well. My system keeps having issues, it seems to be that Avast (antivirus) likes to scan the Gradle processes while building apps. Normally it happens when I try to build and run an emulator, then when I disable Avast the process resumes. This time, my computer locked up, and when I went to load any projects, I got the "Unexpected content storage modification" error.

I found a fix, and all it took was renaming/deleting the .androidStudio hidden folder in Windows, under your home directory. C:\Users\Administrator\.IntelliJIdea13.1(本地修改的地方，由.IntelliJIdea13改成.IntelliJIdea13.1). I renamed mine and I‘m back up and running.
