I found this solution: How to change name of project in Android Studio, but doesn't seem to be working nad I don't want to damage anything so my question - how to change project's folder name?
I can't find any internal solution, so maybe You have any tricks up the sleeves.
1)Select the Entry "Project" in top-left side on the IDE, under the name of your project (The default entry is "Android")
2)Right-click on the name of project, select Refractor->Rename
This trick worked for me nicely. Follow these steps:
STEP 1: Open Android Studio
STEP 2: Create a new project with the desired name.
STEP 3: Close Android Studio.
STEP 4: Find the src folder in your new project directory. Delete it and replace it with src folder of the old project.
STEP 5: All done. Open your project by browsing through the link Open an existing Android Studio Project.
