That seemed clear so far. I suspect a lot of us are having problems with keystores used when posting apps to the Google Play Store, especially if we are trying to update some app that we haven't updated it in awhile and perhaps developed it on a different computer. (Obviously, I am talking about myself as an example.) So now we are trying to post the update and Google is telling us that the jks is not correct for what we are trying to do. For instance, the fingerprint may not match. Many of us app developers are not security experts, so we are at a loss to understand our situation and what to do. I'm hoping to figure it out from your videos, but it could be nice to specifically address this probably common situatiion. Thanks.

It sounds like you're dealing with some keystore related issues. I don't have experience posting apps on Google Play Store, so I may not be knowledgeable enough to address your request. My videos focuses on teaching how to use keytool and keystore. That being said, I think an app requires to be digitally signed using cryptographic keys present in a keystore (JKS). So if you were to update it, you'd need to present the same keystore file else play store won't be able to verify it. This is just a guess, I'm not sure what the exact process it, I have to first learn it. Are there any error messages or details you can provide?
