How to change Android App Name and ID of an existing application?

Question

I have two Android projects in Eclipse. I copied the one project from the other, then changed the app name (in strings.xml) and the project name

Answer 1

My setup

• Android Studio 3.5.3
• Kotlin 1.3.x
• macOS 10.14.6

Solution to Renaming appid

• In Project Explorer, find app/java/com.company.app.
• Right-click > Refactor > Rename, then select Rename Package.
• Look down in the Refactoring Preview and make sure all package references are selected.
• Click Do Refactor.

No need to hack around by hand.
