Java parses the Android manifest file tool class. Input the XML file path to get the APK package name, entry Activity, all permission lists and Activity lists.

Function Description:

xmlHandle()	XML parsing entry method, parsing permission and activity list
findPackage()	Resolve package name information
findLaucherActivity()	Parsing entry Activity

By calling xmlHandle() method, you can directly complete the parsing work. The whole code is as follows, including the test output code:
