Android Keystore File Lost [duplicate]

Answer 1

Actually there is no way to recover your keystore in other way than with tools for recovering deleted files in your OS.

There isn't any tool for pulling keystore from your device or application. Even Google can't restore your keystore from your Google account.

The thing is different when you only lost your password. See https://code.google.com/p/android-keystore-password-recover/

Answer 2

Sorry dear unfortunately you can not update new version of the same application on android play store. you can upload new application with new package name and keystore file. But Google will not allow you to upload new version with different keystore file.

Hope it will help you.

Answer 3

The keystore doesn't need to be uploaded, it needs to be integrated into the apps .apk. Make sure your building the app for release, in eclipse go to file -> and export the app. This will build it with your release keystore instead of the debug keystore.

When you first export your app and eclipse makes you a keystore it is saved in the eclipse\ folder on your computer, try looking there for it. See this post for where your keystore file should be on your computer.

Answer 4

If you lost your keystore then there is no way that you can update the app in play sore( it will cause a signature error )! The only way is that you can create an app with a new package name upload it to store and remove the old app.
