I have found the solution on Mac. (But I think it’s same on Window)
While packaging the Android, unreal will create a folder in [ProjectLocation]/Build/Android/src/com and name the folder as “YourCompany” (According to the option “Android package name” in “Project Setting > Android”).
ex:
if your “Android package name” is “com.MyCompany.[PROJECT]”
It will create folder like “[ProjectLocation]/Build/Android/src/com/MyCompany”
Then if you change the “Android package name” and package again, it will create another folder at same path:
“[ProjectLocation]/Build/Android/src/com/OtherCompany”
Make sure there are just one company folder under “com” folder and your “Android package name” option should match with that name
