Answer 1

问题的原因在于例外的第一行：

  

FATAL EXCEPTION：main进程：pkg.demo，PID：22090 java.lang.NoClassDefFoundError：java.saw.xml.vind.vodem.model.impl.RuntimeBuiltinLeafInfoImpl的java.awt.Image。

Android无法找到班级java.awt.Image。这是因为Image是一个AWT类; AWT是Android中不存在的工具包。

此错误源自com.sun.xml.bind.v2.modle.impl.RuntimeBuiltinLeafInfoImpl。所以，似乎你已经添加了一个依赖于AWT的库。

解决方案是查看此库是否已移植到Android;然后使用Android端口 如果没有端口，则必须找到另一个库。
