If you're developing a web application for Android or redesigning one for mobile devices, you should carefully consider how your web pages appear on different kinds of screens. Because Android is available on devices with different types of screens, you should account for some factors that affect the way your web pages appear on Android devices.
When targeting your web pages for Android devices, there are two fundamental factors that you should account for:
1) The size of the viewport and scale of the web page
2) The device's screen density
Here is the example:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.1//EN"
"http://www.w3.org/TR/xhtml-basic/xhtml-basic11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang=="en">
<head>
<title>Page title</title>
<meta name="viewport" content=
"width=device-width, target-densitydpi=device-dpi" />
</head>
<body>
</body>
</html>
Here is the syntax:
<meta name="viewport" content="
height = [pixel_value | device-height] ,
width = [pixel_value | device-width ] ,
initial-scale = float_value ,
minimum-scale = float_value ,
maximum-scale = float_value ,
user-scalable = [yes | no] ,
target-densitydpi = [dpi_value | device-dpi |
high-dpi | medium-dpi | low-dpi]"
/>

HTML is overkilled for mobile device
HTML is a powerful language for authoring Web content, but its design does not take into consideration issues pertinent to small devices, including the implementation cost (in power, memory, etc.) of the full feature set. Consumer devices with limited resources cannot generally afford to implement the full feature set of HTML
XHTML Basic 1.1
The motivation for XHTML Basic is to provide an XHTML document type that can be shared across communities (e.g. desktop, TV, and mobile phones), and that is rich enough to be used for simple content authoring.
What does it look like?
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML Basic 1.1//EN"
"http://www.w3.org/TR/xhtml-basic/xhtml-basic11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang=="en">
<head>
<title>Page title</title>
</head>
<body>
</body>
</html>
