The person who made the application had to leave the Keystore with which the application was signed as well as the passwords.
I had never worked on a development for Android, so I give myself
account that you have to generate a signed APK. At the root of the project
There is a file called APPLICATION_NAME.keystore.
This is probably the Keystore with which the application was signed because when you create a project, a Keystore file is not created automatically.
When you test your application it uses the development Keystore, which is not to upload the application to Google Play, this file is located in:
C:\Users\<USUARIO>\.android\android.keystore
When trying to generate the APK, I am asked for other fields that are: Key

Is there any way to get them, from Google Play Console for example? or in
If you can not get them, you can not update the application?
If you do not get them, unfortunately you will not be able to update the application, you will have to upload a new application.
