How to clean a project in Android Studio? I have changed the project from Eclipse and my apk file is not updating, it contains the old apk file from Eclipse. I did rebuild project, doesn't help. Also checked Out folder, no apk for this project is there. Also I changed my project name once while it was in Eclipse. Now the Out folder still contains the old projectname.apk file. Would really appreciate your help.

When you think that Android Studio (or Intellij IDEA) isn't picking up an externally made change, sometimes File -> Invalidate Caches... can help.
