我想与androguard dx.get_classes，但我得到错误

Question

我想从apk文件中提取类。为此，我在santoku中使用了androguard。但是当我编写代码时：

AttributeError                            Traceback (most recent call last)
/usr/share/androguard/androlyze.py in <module>()
----> 1 dx.get_classes()

AttributeError: uVMAnalysis instance has no attribute 'get_classes'

我收到此错误。

a, d, dx = AnalyzeAPK("/home/nida/Desktop/a.buddist.bible.AOVWPEUKAUHBZRSJY.apk")

当我编写此代码时。我可以获得许可，活动等。[a.get_permission(), a.get_activities() ...]

但是当我写

dx.get_classes()

我遇到此错误：

AttributeError                            Traceback (most recent call last)
/usr/share/androguard/androlyze.py in <module>()
----> 1 dx.get_classes()

AttributeError: uVMAnalysis instance has no attribute 'get_classes'
