I want to rename my Firebase id.
I found out that the only way to do that is to create new project
How can I rename the Firebase Project ID?
I've created a new project and pasted the same android applicationId.
I've added the correct json file into my project.
Then Firebase suggests me to run my app in order to test the connection. I've reinstalled my app, but I have no connection. Does it mean that I should delete the prerious app in order to make this app work?
