I am a newbie to Android development so please forgive me if I am not asking the question correctly.
Before I got into Android Development myself very recently, I managed a few Android projects with an external vendor who would publish the app from their own account.
Now the vendor's developer is gone and we need to publish version 2.0 of an app previously, developed and published by the vendor. The vendor's developer is gone and all we have is the source code (and no key, keystore etc. that is required to publish the new app as version 2.0).
We have already begun the process of transfer of ownership for the app from the Vendor's Google Play Developer account to our Google Play Developer account as described in Transfer apps to a different developer account
The above takes care of the transfer of the app ownership, but not the publishing of version 2.0 on the same app. Can someone from the community please let me know precisely what all should I be asking the vendor manager to give us (and where should he be looking for these files on the developer's machine) to enable us to publish version 2.0? (Unfortunately, the vendor manager is not too familiar with Android development).
Update: The vendor manager has reverted back with saying "***************" is the key that was used in signing. According to me, a .keystore physical file would be required and "***************" this would be just the password for accessing that .keystore. Android experts, please validate if my thought is correct.
