Android : How to change my android app id

I want to change the app ID (eg. com.kenz.myapp.app to be com.lionz.myapp2.app)

I tried to replace all IDs with a new one but I get this error

Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.kenz.myapp.app/com.lionz.myapp2.app.login }
Error type 3
Error: Activity class {com.kenz.myapp.app/com.lionz.myapp2.app.login} does not exist.
