[Android] teaches you how to get resolveinfo (non-reflective, manual parsing) for apps that are not installed

Principle: The principle is not much said, look under the Android source code will know. First get Assetmanager, then use Assetmanager Openxmlresourceparser method to get Xmlresourceparser, Start parsing the Androidmanifest.xml file in apk with Xmlresourceparser
Solution: Directly on the code bar, very simple.
