[FIXED] Sign with the debug key on Google Play

Issue

I haven't configured signing in gradle file and I released my app to Google Play successfully.

Upload certificate on Google Play:

SHA1: B5:E0:B6:51:92:27:09:2E:C2:6A:BF:BF:5F:94:82:C5:2E:BF:12:08

debug.keystore file:

androiddebugkey, 2017/9/24, PrivateKeyEntry,
(SHA1): B5:E0:B6:51:92:27:09:2E:C2:6A:BF:BF:5F:94:82:C5:2E:BF:12:08

I realized that I released my android app to Google Play with a debug key and somehow the Google Play Console couldn't detect that it was a debug key.

Today I want to update my app, the Google Play Console reject my file. (Signing in debug mode)

Is it possible to fix it?

Solution

If you used Google Play App Signing you can contact Play Console support and they can help you change your keys (see the steps to take at the bottom of the article).

If you didn't use Google Play App Signing there is nothing you can do except re-publish your app under a different package name.

A good reason to use Google Play App signing.
