Yes, HTML is supported in Android. In fact, Android's native browser, WebView, is based on the opensource Chromium project which uses HTML as its main markup language. This means that you can develop web applications that target Android devices using standard HTML, CSS, and JavaScript technologies. Additionally, many native Android apps also support the use of HTML for rendering dynamic content or working with embedded web views. Overall, HTML is a versatile and widely supported technology that can be used to develop web-based applications across multiple platforms, including Android.
