问题
I have run into this annoyance over and over again and have been unable to find a solution or an answer here for it:
When I create a package in my application and then add a package within it, if I do not have a file in the directory already it will auto collapse my package in the left-side navigation of Android Studio. This prevents me from adding other sub-packages to the parent package, without manually resolving the issue within the file system.
For Example:
What I want is:
-presentation
-screens
-devicescreen
-adapters
-presenters
-views

In the 1:Project view, you have Hide Empty Middle Packages turned ON. You need to turn it off. Once turned off it will be shown as Compact Empty Middle Package. Please look at the screenshot attached.
