I'm trying to sign a Android App Bundle and I'm having some problems. This is an old app that have been disabled from the play store, and now I'm trying to restore it. First thing I need to upload the new version to the play store, to which I need to sign the app bundle.
My first try was the Generate Signed Bundle option on Android Studio. I've generated a new key, and build the app. But when I tried to upload the generated file into play console, I got the message below (A free translation from the Portuguese message I got):
Your Android App Bundle was signed with an incorrect key. Use the right signing key and try again. It should be signed with a certificate with the following digital print:
SHA1: {Big sequence}
. Nonetheless, the certificate used to sign the app bundle uses:
SHA1: {Another big Sequence}
So I concluded there is already a key in play console I Should use to sign the application. When I access the play console, I was able to find some keys, as shown in the picture bellow:
There is a download certificate button, which will download a .der file, but I don't know how to use this .der file to sign the app bundle. How can I do that?
