you how to start android development with the very first android project.<\/p>\n<p>As a beginner first of all you must develop the hello world application like we do while learning a new language. This project doesn&#8217;t involve any business logic rather it ensures whether our development, as well as the deployment environment, is working. This is indeed a very simple android project and you do not really need to do a lot of coding here.<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/05\/android-hello-world-program.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-78301\" src=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/05\/android-hello-world-program.jpg\" alt=\"android hello world program\" width=\"802\" height=\"420\" srcset=\"https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/05\/android-hello-world-program.jpg 802w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/05\/android-hello-world-program-150x79.jpg 150w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/05\/android-hello-world-program-300x157.jpg 300w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/05\/android-hello-world-program-768x402.jpg 768w, https:\/\/data-flair.training\/blogs\/wp-content\/uploads\/sites\/2\/2020\/05\/android-hello-world-program-520x272.jpg 520w\" sizes=\"auto, (max-width: 802px) 100vw, 802px\" \/><\/a><\/p>\n<p>This application will be a very simple project that will have only one activity that will show a message that is \u201cHello World\u201d. Without any further ado let&#8217;s see what all files would be there in for the application. We\u2019ll also tell you why these files are created and their usage. In this android project, there will be two mandatory files that are<\/p>\n<ol>\n<li><strong>activity_main.xml:<\/strong> This file is used for the layout of the application.
