In this article, we'll explain in detail how to use the Cordova Camera HTML5 app. For more information on Cordova development guidelines, developers can refer to the article "The Cordova Guide". With this routine, we can learn how to use the Cordova API on the Ubuntu platform to accomplish a camera function that we need. For a simple application of how to create
