Android Studio I keep getting Gradle error "The process cannot access the file because it is being used by another process"

Question

I can import a sample app project, try to build it and I keep getting this error. Not always the same file but a new temp file each time. I've tried several different samples. I've been programming for 30+ years and feel completely clueless. Only clue seems to be the Windows Task Manager shows 99% to 100% CPU usage when it gives the error and ends the build.

Answer 1

Do This

File -> Invalidate Caches / Restart.. -> Invalidate/ Restart

Answer 2

When this happens to me on Windows 8, I open the task manager

and simply kill all the instances of "openjdk platform binary"

Answer 3

Just clean the project and have a run ! It would work ....

Answer 4

Choose app instead of DefaultPreview. Now if you build, then you should not see this issue.
