Only application id.
Thank you Anton for the reply, I will test it.
Best regards
Wel, I just play a little bit and change only app ID but I still can not rebuild the project , I am using firebase JSON file with package name: org.traccar.client and I changed the application ID to : info.traccar.client and when try to rebuild the project I am geting this error:
org.gradle.api.GradleException: No matching client found for package name 'info.traccar.client'

Do I need to change a package name from org.traccar.client to something else to publish app on the Google playstore or I just need to change application ID to publish unique app to the Google playstore?
