问题
My Android App already has a SHA1 fingerprint on Google developers console generated by another developer some time back. Now, I am debugging Google Sign-in bug in the App and it turns out that Google Sign in uses the default SHA-1 found in .android/debug.keystore to make a request in the OAuth authentication process. And I had generated a new debug key yesterday because after all it is debug.
How do I add or incorporate this new debug key to Google's developer console to make a successful Sign in request?(I don't want to replace the old key)
回答1:
Go to Google Cloud Platform Console or Firebase. You'll find the project there. Click on the project and you'll get into the dashboard of the same. In the bottom of the dashboard there'll be SHA key. Click add key and add the new key there. The Google Services which you have used in the app will run fine now.
