Android Intent Value-Transfer considerations

For example, interface a passes value to interface b

1. Interface a considerations:

(1) Intent put different types of parameters with the same name parameter the last one will overwrite the previous parameter (one parameter name can only correspond to one parameter value, and multiple parameters will be overwritten by the last parameter)

2. Interface B Considerations:

(2) Intent get different types of parameters, only if interface a put the parameters of the type, B interface to get to the value, otherwise get will be null; (interface aput what type, interface B can get to what type)
