Error on compile to Andriod when apply certificate - codenameone

Question

My app compile for android ok.
When I create the android certificate, and send to the codename compiler it don´t compile.
I tried to generate the certificate with the keytool and tried with the assitant on codenameone, the result is similar.
If I delete the keystore file and resend to the dashboard, the app compile ok.
This is the log errors

This has nothing to do with the certificate. It fails in the obfuscation stage before the certificate. These errors are notoriously hard to read and it seems you snipped it a bit too late. I need the section above that which includes the detailed warning about the class/method that isn't found.
Go to the error and scroll a bit higher and look for a familiar class name with a proguard warning next to it. This is the class causing a problem probably because of a missing dependency. If you can't find it just post the log link to the website chat and our support will look over that for you.
