Practical No 29

The document contains code for an Android application that allows users to send SMS messages. It includes an XML layout file for the user interface with two EditText fields for inputting a phone number and a message, as well as a Button to send the message. The Java code handles the button click event to send the SMS using the SmsManager, with error handling for empty fields.
