android build warning: Ignoring InnerClasses attribute for an anonymous inner class

warning: Ignoring InnerClasses attribute for an anonymous inner class(com.umeng.socialize.bean.a) that doesn't come with anassociated EnclosingMethod attribute. This class was probably produced by acompiler that did not target the modern .class file format. The recommendedsolution is to recompile the class from source, using an up-to-date compilerand without specifying any "-target" type options. The consequence of ignoringthis warning is that reflective operations on this class will incorrectlyindicate that it is *not* an inner class.warning: Ignoring InnerClasses attribute for an anonymous inner class(com.umeng.socialize.bean.b) that doesn't come with anassociated EnclosingMethod attribute.
