I tried to implement Firebase Cloud Messaging but I messed something up, so I Deleted the Project and unpacked my Backup.

Now I want to connect my app with Firebase again, but the problem is that it's saying that my SHA1-Certificate is already used by another app (of-course) and now I cannot link my app again.

How do I remove the connection between the SHA1 Certificate and the old App? Also, do I have to wait for 30 days now for the old Project being removed?

Just remove the app from the other project where you originally added it with the same package and SHA-1. There is a "delete this app" button at the bottom of the general setting page that shows all the apps you previously added.

  • Thanks Doug. It would be more helpful if you can show a screenshot, since I couldn't find any "delete this app" button in my signing report. :( – Rohit Sharma May 12 '18 at 02:34
  • Firebase console -> your project -> Project settings (gear icon) -> Select app -> Delete this app – Doug Stevenson May 12 '18 at 02:45
  • Oh yes you mean login to Firebase. I was searching in my AS project. Thanks so much Doug! :) – Rohit Sharma May 12 '18 at 02:54
  • Doesn't work for me, if i try to Connect to Firebase through Android Studio still says that my SHA1 is already used by another app. Is there a way to get a different SHA1? – Percdye7 May 12 '18 at 15:00
