In this post, I am going to discuss about how to authenticate Users in Android application using Dot Net Web service.The application which I am gonna create will have two screens – Login screen and Home screen.
User has to type his/her credentials and click ‘Login’ button. Once ‘Login’ button is clicked, application fires call to Dot Net web service along with Username and Password typed by User. Our Activity waits for response from the web service, once it receives response, it decides whether to take User to next screen(Home) or show ‘Login Failed’ message based on the response.
Here is the graphical representation of whatever we discussed:
In this post we will be discussing on how to consume JSON response (returned on invoking web service) in Android applications. I took simple example to demonstrate the JSON Web service tutorial. The example which we are gonna create will have two spinner controls (called Dropdownlist in traditional desktop applications), one to display ‘Countries’ list and other to display ‘Cities’ list.
When user selects a country from the ‘Countries’ spinner control, cities belong to the selected country will be populated in the ‘Cities’ spinner control.
It was bit difficult to find out a good tutorial on how to call ASP .Net web service from inside Android application so I just decided to write one.
In this post, we are going to discuss about calling a web service from inside an Android application that has been developed using ASP .Net technology.
Before we start with developing application, create a simple web service and deploy it in IIS server (server installed in your local machine or hosted server).
