The requirements for using XBinder with Android have changed. Since Android API Level 8, Android now includes certain classes that XBinder uses which were not previously supplied. Goind forward, you simply need to generate code using the -xpp command-line option (specifies use of XmlPull Parser). You may also need to include Xerces in your build.gradle file (see the sample for an example), since Android does not provide an implementation of java.xml.datatype.DatatypeFactory. Android API Level 7 and below is no longer supported.
