warning: Ignoring InnerClasses attribute for an anonymous inner class
(com.alipay.sdk.app.H5AuthActivity$11) 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.
