How i can app signed with Expo.

I asked Google for a new signature. Google has approved my signature. It will be active after 2 days.

Now how do I get build with upload_certificate…pem file?

i get keystore format error. :frowning:

I have the same issue, did you find a solution ?

yes. generate new key from expo and send the google. this solved for me.


are these the steps I need to follow? and will I be able to update my existing app using this approach or do I have to remove the app from play store and create new one?

Run expo build:android -c and let expo to handle credentials. After build is complete run expo fetch:android:upload-cert , this command will create .pem file.
Go to google play console and ask google play support team to reset your upload cert / keystore. In “Upload certificate” section of “App signing” page there will be link to contact them. Attach .pem file to the message.
