I am new to Android Development. So, I've been trying to publish my app on Play Store for the past week now. I had no ideas about keys and signing the apps. I went ahead and tried to publish the .aab file but that file got rejected for some reason.
I created multiple new projects with the same code one at a time and due to this, I created multiple keystores, keys, release and debug files.
I couldn't understand what went wrong, so I deleted all the project files and created a brand new one.
So yesterday, Play Console showed that I was signing in with the wrong key.
I remembered that I could restore them from the recycle bin so I did. But now I got a major problem. I have an .aab file which has an incorrect app id and the correct signing key whose ID I need to change in order to publish it on the Play Store. I have a lot of project files so it's really confusing for me to decide which file is which.
So, I need to change the app ID in my .aab file because Play Console won't accept 'com.example' files but I don't have its project.
(I need to change the ID of the .aab file without having any access to it's related files or projects).
