    Uploaded by

    shafe SP
    The document describes creating a web service in Android using URL connection to demonstrate arithmetic functions. It includes XML layout files for main and addition activities, with buttons and edit texts. The MainActivity calls a web service and displays the response. The addition activity gets two numbers from edit texts, calls a sum web service, and displays the response. The code includes an AsyncTask to call the web services and handle the responses.
