Well, short answer – no.
Most android apps are developed using Java as the programming language, with a mark-up language which could be comparable to HTML (but is not HTML) to build the basic UI structure of most screens.
Certain aspects of HTML are still used in Android apps, for example, when we’d like to construct a label with styling (such as a bold word in the middle of a sentence, etc). Also, Android is capable of presenting a WebView which can display HTML and run JavaScript. There’s also a way to leverage HTML to make apps which can run on both Android and iOS with only 1 development cycle. These apps are good on cutting costs, but usually fall short on performance.
Games, however, usually do not rely on HTML due to the high reaction time required of them, and their intensive graphic requirements.
Some developers develop games for Android using the basic Android APIs available, such as Canvas, or OpenGL-ES. Others chose to opt for game development tools such as Unity.
