How do you rename packages in the new IDE Android Studio, based on IntelliJ IDEA?
Is there an automatic refactoring included?
I want to make bulk refactorin
This I believe what you are looking for is Refactor > Move. You can also press F6.
You will get two popups. Make sure you select rename package on both. After that you will get a pop up to place the new package name.
Please note that if your package name is, for example, com.example.android.projectname then this will let you change com.example.android to something else.
One more thing, this will update the applicationId in your build.gradle as well. Just make sure that the checkboxes for "search in comments and strings" and "search for text occurrences" are both checked for it to work.
