导出.apk时Joda时间和ProGuard错误

Question

In Eclipse when I export my .apk and enable proguard I'm getting the following build errors:

[2014-07-10 04:13:30 - VirginMobile] Proguard returned with error code 1. See console
[2014-07-10 04:13:30 - VirginMobile] Warning: org.joda.convert.JDKStringConverter$9: can't find referenced class javax.xml.bind.DatatypeConverter

Couldn't find a solution in any other threads.

I included both joda-time-2.3.jar and joda-convert-1.6.jar (which took away all but three errors). Anyone know how to fix this?

Much appreciation.

Answer 1

The Joda class org.joda.convert.JDKStringConverter makes use of the Java API class javax.xml.bind.DatatypeConverter , which is not available in the Android API.

Joda may still work on Android if you don't actually use the JDKStringConverter class, but ProGuard tries to ensure that all dependencies are fulfilled.

You could try to tell ProGuard to ignore the missing dependency with the option "-dontwarn javax.xml.bind.DatatypeConverter".
