We lost the keystore file for our Android application... And would like to replace the current application with a new app signed with a different keytore from the original app. If we unpublish the app, is it possible to upload the new app with same package name? Or are we forced to upload it with a new package name?

Edit: The .keystore file is missing, not the password.

Normally, if you unpublish, re-sign your app with new certificate with new keystore and publish again, it will work.

  • If the same App is signed with a different key, any existing installations cannot be upgraded - the user will need to manually uninstall the old version and then install the new version. – adelphus Aug 07 '15 at 12:33
  • @fab Normally? There is no guarantee that it will work? – trevligheten Aug 07 '15 at 12:36
  • @adelphus That is no problem, I just want be sure it will work before I get to work unpublishing and stuff. – trevligheten Aug 07 '15 at 12:37
  • You can try it with a stub application that you can publish temporarily on the store. It won't cost you a dime :P – Eduard B. Aug 07 '15 at 12:47
  • @trevligheten if you unpublish the app, it is no more registered in google play store, this means you can use again same package name, you need to test :) – fab Aug 07 '15 at 13:55
  • @trev you have to unpublish anyways, there is no way to upload an app to the old entry. Unpublishing just means its no longer available, but the users who have already installed it will still be able to use it. – tritop Aug 07 '15 at 14:23
  • I unpublished my app. Again signed with different keystore. But play store is not accepting from same account. – Rahul Rastogi Feb 21 '17 at 05:25
  • @Rahul Did you use the same package name? Did it work with a different package name? – app-dev May 01 '18 at 16:38
  • @Schreiby Changing package name definitely works with new keystore! But cause loosing all existing app's history like: likes, comments, download counts and offcourse app itself. – Rahul Rastogi May 02 '18 at 10:37
