Soap in android #android #soap protocol #xml

Today I will explain to you how to load data using soap. Soap is not much used today but it has its own features like security so it is used even today

Points to Note
SOAP is a communication protocol designed to communicate via Internet.

SOAP can extend HTTP for XML messaging.

SOAP provides data transport for Web services.

SOAP can exchange complete documents or call a remote procedure.

SOAP can be used for broadcasting a message.

SOAP is platform- and language-independent.

SOAP is the XML way of defining what information is sent and how.

SOAP enables client applications to easily connect to remote services and invoke remote methods.
