I lost my keystore file to sign my android app on google play. I have the user, alias and password that i used. Is is possible to generate a new keystore using the same credentials so i can update the app? Thanks!
I suffered from the same...Unfortunately, there is no solution to it because it does not rely on its user/password.
It relies on MD5 or SHA1 signature which is auto regenerate [randomly] when the new file is created.
And while uploading the updated app version if this signature is not the same, the Google play store will not accept the new app version of that package.
This time I would suggest you keep a copy of the .keystore file at drive, mail, etc....
And don't try to upload the same application with a different package name because the Google play store will automatically suspend your application if it finds any similarity with other and this is totally computerized.
