Cleaning project in Android Studio also solves other types of errors that occur in the project.
But what are the specific project problems that cleaning project can be used to solve? Many says clean project but when to clean the project?

You should clean the project when the issue is related to the build of the project. This especially includes code generation with Android Studio and Annotation processors.

Also it should be done as last resort when you're out of ideas; just to be sure before asking for help.
