Delete a Firebase Android app, then use its SHA1 and package name in another project

问题

I'm using Firebase for its Firebase Cloud Messaging service. I have 2 account, each of which has a project with and Android App.

Account A -> Project A -> Android App A
Account B -> Project B -> Android App B

I need to delete Project A and migrate everything to Project B (Android and iOS apps, nothing else).

Here's what I've done so far:

1. deleted Android App A
2. created Project B
3. created Android App B

I now need to add the SHA1s, used in Android App A, in Android App B, but I always get an error.

I'm thinking this could need some time to take effect, during which time I can't use the same SHA1 in another app.

• Is this the case?
• How long should it take?
• Am I missing something?

回答1:

It takes up to 1 month to delete a project from firebase to prevent unintended removal. AFAIK, you cannot use your key during that period.

upd. If you used a debug store (usually placed in ~/.android/debug.keystore) and generated 'androiddebugkey' like this

keytool -list -alias androiddebugkey \
-keystore ~/.android/debug.keystore \
-storepass android -keypass android

you can always delete the ~/.android/debug.keystore file and generate new SHA1.
