Android Studio error 100% solution

Your Android App Bundle is signed with the wrong key. Ensure that your app bundle is signed with the correct signing key and try again

Error number one: 

You need to use a different package name because 'com. example' is restricted.

Error number two : 

Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key and try again. Your app bundle is expected to be signed with the certificate with fingerprint:

SHA1: AF:B7:23:F7:EE:DD:D3:82:5A:CF:F8:C0:57:E2:4D:F1:A0:AD:B3:C4

but the certificate used to sign the app bundle that you uploaded has a fingerprint:

SHA1: 4E:E4:20:0A:51:67:F0:08:13:9D:AC:FB:94:41:C8:A1:18:6C:A7:0B

Solution : 

The error message is telling it all. You need to use a package name of your own. The package name is the identity of the application.

ie. when you create an Android Studio Project you have to simply make changes in the below box
