Android Signature tampered with (Keystore is tampered with, or password was incorrect)

"Keystore is tampered with, or password is incorrect" error occurred while configuring custom signatures!

Reference Document Discovery:

If necessary, you can change the location/name of the debug Keystore/key or supply a custom debug Keystore/key to use. However, any custom debug Keystore/key must use the same Keystore/key names and passwords as the default Debug key (as Des Cribed above). (to doing in Eclipse/adt, go to Windows > Preferences > Android > Build.)

Because the configured custom signature is used for publishing, the password is also a custom company name, which is different from the default Debug.keystore password Android, resulting in an error!

So it seems that the custom debug signature doesn't make any sense, at least I haven't found it yet.

The custom signature only needs to be in the build apk is made by Android Tools---Export signed application package
Export!
