You can go into the project directory and call gradle from the command-line to do a clean on the project:

gradlew clean

I'm not on Windows, but OS X. Somehow my build folder didn't have the proper permission for AS to delete the file so I did chmod -R 777 <your_directory> in the affected parent directory.. probably 777 isn't what you would want but it worked for me.

I had the same issue as you. I tried some of the solutions proposed on this page and it didn't work. So I used Process Explorer to find which process is locking the apk file and it was firefox. I think it keeps the file locked when I upload the apk in google play console. To make that go to "Find > Find Handle or DLL... > path-to-your-app.apk". Hope it help

I came to this thread because I was having issues with my /release/app.aab getting locked. This prevented me from completing a project clean and generating a signed bundle. My work around was to restart my computer to get permissions back until I solved the issue.

Hope this helps someone.
