Android: How to use more than 1 package in the Facebook app configuration

Can i have more than 1 package name in the Facebook configuration settings to work with Facebook API in my application.

enter image description here

I must be able to use the same Facebook app for different Android apps right?

How do I change Facebook app developer?

You can access the Developer Settings panel by going to the Apps panel or developers.facebook.com/docs, hovering over your profile image in the upper right corner, and selecting Developer Settings from the dropdown menu.

you only need a key hash. No need to enter package name and class name. For your Facebook Integration.

You'll need to create a new Facebook app for each of your Android apps. Multiple package names would break many features, such as deep linking. I think it's also used for storing Facebook permissions so users can easily revoke an app's permissions.
