android ChatDemoUI3.0 Demo eclipse编译报错

Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(com.xiaomi.network.d) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.
