The apk must be signed with the same certificates as the previous version

Question

I had uploaded my app to Google Play (back when it was called Android Market) some time ago.

Today I updated the app, but I had deleted the previous keystore and cre

Answer 1

My [silly] mistake was that i used app-debug.apk file instead of app-release.apk file. You need to to choose "release" in "Build Variants" frame when you generate signed APK. The app-release.apk file should be located under "app\release" folder in your project root.

Answer 2

Nothing - Google says it clearly that the application is identified by the keys used to sign it. Consequently if you've lost the keys, you need to create a new application.

Answer 3

I just had this occur out of the clear blue. I really do not think I changed anything.

However, Build => Clean Project fixed it.

Answer 4

Here i get the answer for that question . After searching for too long finally i get to crack the key and password for this . I forget my key and alias also the jks file but fortunately i know the bunch of password what i had put in it . but finding correct combinations for that was toughest task for me .

Solution - Download this - Keytool IUI version 2.4.1 plugin

the window will pop up now it show the alias name ..if you jks file is correct .. right click on alias and hit "view certificates chain ".. it will show the SHA1 Key .. match this key with tha key you get while you was uploading the apk in google app store ...

if it match then you are with the right jks file and alias ..

now lucky i have bunch of password to match ..

now go to this scrren put the same jks path .. and password(among the password you have ) put any path in "Certificate file"

if the screen shows any error then password is not matching .. if it doesn't show any error then it means you are with correct jks file . correct alias and password() now with that you can upload your apk in play store :)

I highly recommend Keystore Explorer (https://keystore-explorer.org/) which lets you access your keystore without having to upload it to Google Play. This way you can troubleshoot whether you are entering your password incorrectly.
