Some errors reported by Xposed for HOOK

NosuchMethod：

Incorrect number of parameters will cause this error;
Package name, class name is wrong

When the prompt cannot hook abstract classes, ie abstract 

Find the implementation class method of the abstract class for hooking
For example: abstract class -> HttpURLConnection
Find a way:
    HttpURLConnection conn = (HttpURLConnection) httpUrl.openConnection();
    Log.d("Get the implementation class",conn.getClass().getCanonicalName().toString());
This will print to the log of the android device monitor
