Has anyone figured out the new Google Play App Signing process? I can download the .der file , but I don't know how to use it to sign my app. I'm getting an Invalid Keystore format when I try to sign with the file. I used to have a app signing tool on Eclipse that I don't have on Studio. Anyone have a suggestion for how to make this work?

Perhaps this can help? https://coderwall.com/p/zrdsmq/signing-configs-with-gradle-android I haven't worked with android in a while, so I'm not sure. Good Luck! Cheers! -- Smug

I didn't know Google Play have changed the process! I just used my old keystore from the good old Eclipse days. When did that happen? Alan

Google apparently has a new option (that I elected, unfortunately) to store your keys for you. If you have ever gone through the trauma of losing an Android app key, this new process may be better. But I thought it would be easy to make the switch, and it hasn't been. I think the problem is that I had already signed my app with my own key, and that doesn't work any more (for me). But because it is already signed, the wizard that should show me how to sign isn't coming up to help me. I haven't had a chance to go through Smug's link yet, but it seems pretty complicated. I don't file that many apps with the Play Store, so it is also possible that this is such a brand new thing that the solutions aren't documented on Stack Overflow or the Buzztouch Forum yet.

Aah, I see. I think from what you've said that the either the old way and new way are not directly compatible or that in the new way google has interprested your key differently and it thinks they don't match. I'm not expert in Android but I have a suggestion - you may have tried this but in case not, have you tried using your Android key in the old-fashioned way? If you are using Android Studio I find that still works and last time I updated an app, google compared the key in the new app to the key in the old app as it uploaded and it just worked.

Here is a link to the new process: <a href="https://developer.android.com/studio/publish/app-signing.html" target="_blank" rel="nofollow">https://developer.android.com/studio/publish/app-signing.html</a> You can either sign apps the old way (now called the Manual way) or with the Google Play process--the new way. If you ever have lost the signing key for an Android app, you can see why this new process is better, at least theoretically.

Looks like it was announced on May 22. https://www.digitaltrends.com/mobile/google-play-app-signing/

I can see if you lose a signing key it might help, but in your case it sound as if Google did the equivalent of losing it for you! Looks like the process edits the APK after upload. I'd be interested to know if there is anything specific that needs to be done or considered for a buzztouch app to support this or if it just works.

What I ended up doing was to create a new app in the Google Play Developer Console.
