Lost My Keystore for Uploaded App on Android Market

I lost my .keystore file?

Faced the same problem. I was trying to restore it via deleted files restoring tools, but it failed. So, there is no other way: you should issue another application.

Generally, the only advise that exists on keystores: "always back it up!"

I lost my Keystore used to sign my apk. Is it possible to reupload in play store?

Yes, you can delete the previous application and re-upload it.
You won't be able to use the same package name though, as it will already be taken by your old app.
Simply re-upload it as you would when you want to publish a new app.

But remember,
you should always keep your keystore and passwords saved!

I lost My Keystore file. now how can i release update?

Keep your keystore and private key in a safe and secure place, and
ensure that you have secure backups of them. If you publish an app to
Google Play and then lose the key with which you signed your app, you
will not be able to publish any updates to your app, since you must
always sign all versions of your app with the same key.

There's no way to recover your key . Lost my keystore for uploaded app on android market .

So finally, Its not possible. Please Create new keystore with the application with different package name and version and publish as a new application.

Lost my keystore for uploaded app on android market

There's no way to recover your key. I once accidently deleted mine and faced the same problem. I ended up emailing the few users who had already purchased my app about my mistake and told them to let me know who they are and that I would refund their purchase of the app again, if that's what they wanted. Since then, I've made several copies of my key. Once again, there is no way to recover this.

On the other hand, you could try doing a system restore, on your computer, to a previous date in which you haven't misplaced or deleted your key yet.

Android: I lost my android key store, what should I do?

You can create a new keystore, but the Android Market wont allow you to upload the apk as an update - worse still, if you try uploading the apk as a new app it will not allow it either as it knows there is a 'different' version of the same apk already in the market even if you delete your previous version from the market

Do your absolute best to find that keystore!!

When you find it, email it to yourself so you have a copy on your gmail that you can go and get in the case you loose it from your hard drive!

Lost keystore password, but let Google Manage Signing Key

Because you've enrolled in Play Signing (i.e. "Manage Signing Key by Google"), then you can contact Google Play developer support and ask them for instructions on how to reset the upload key for your app. This will consist of creating a new keystore and sending them the new certificate (after you have proved your identity).

You will then need to change your signing configuration in your Flutter project to reference the new keystore.

After that, you'll be able to keep uploading updates of your app to the Play Console and your users will keep receiving updates as before.

The keystore you lost is what Google calls "upload key": it's only used to verify that what is uploaded effectively comes from you. But Google has a hold of the app signing key which it uses to re-sign the APK that are served to users.

The full documentation around Play Signing can be found here: https://support.google.com/googleplay/android-developer/answer/7384423

Lost keystore file for app (but have Google Play App Signing enabled)

Seems it should work.
"Manage your app signing keys
With Google Play App Signing, you can securely manage your app signing keys for new or existing apps. Keys are stored on the same secure infrastructure Google uses to store its own keys.

If you lose your keystore or think it may be compromised, Google Play App Signing makes it possible to request a reset to your upload key. If you're not enrolled in Google Play App Signing and lose your keystore, you'll need to publish a new app with a new package name."

Android Keystore File Lost

I lost my key store password, I want to update my app on plays store with same keystore

Sorry, the answer is there's absolutely no way to update your app with your keystore without the password.

You have to unlist your app and build with a new keystore, list a new one. Users will not see the updated app because the listing is now pointing at a different entry.

Please keep your keystore file like your life.
