Android was created in 2003 by Andy Rubin, who first started developing an OS for digital cameras. Soon, he realized that the market for digital camera operating systems perhaps wasn’t all that.
What is the history of Android?
Rubin described the Android project as tremendous potential in developing smarter mobile devices that are more aware of its owner’s location and preferences.
As Rubin said in 2013, “The exact same platform, the exact same operating system we built for cameras, that became Android for cellphones.”. In 2005, the next big chapter in Android’s history was made when the original company was acquired by Google.

What are the advantages of using XML for Android app development?
The biggest advantage of writing your app’s in XML, in terms of readability, is that XML is structured in hierarchy. The layout relationships between elements are immediately visible. If you construct your Android app without XML, you programmatically append children to their parent.
Its also easier for people to describe a layout in XML than in java directly. This technique is used by a lot of things, eg WSDL that describes a web service interface and is converted to (quite complex) code by a specialist tool.
