NoClassDefFoundError，再Patch之后，会在原本的类后添加了_CF后缀，然后就找不到了。
异常的打印信息如下：

最后一句：
Caused by: java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack available
会是造成异常的原因吗，求解。
AndFix supports Android 2.3 to 6.0, arm and x86 architecture, dalvik runtime and art runtime.
这是readme里面的内容。 行，我再换一个试试。
