1. Start a new project in Android Studio by opening it. Run code to start a new project using Android Studio. Both Java and the Android programming language Kotlin have been provided with the code for it.
2. Using the XML Files. Next, navigate to the activity main.xml file, which is the project's Interface. The code again for activity main.xml file is shown below. Inside the code, comments are added to help the reader comprehend it better.
3. This file includes a Relative Layout with three Editing texts for the recipient's email address, another for the email's subject, and a final one for the body, along with three TextViews for such label and just a button for launching the intent or sending the email.
