codenameone - Error on compile to Andriod when apply certificate

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

Answer 1

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.
