	device	The device design name.
	fingerprint	A unique identifier for the currently-running build.
	host
	ID	A changelist number or label.
	model	The end-user-visible name for the device.
	product	The overall product name.
	tags	Comma-separated tags that describe the build, such as "unsigned" and "debug".
	type	The build type, such as "user" or "eng".
	user
	CPU_ABI	The name of the native code instruction set, in the form CPU type plus ABI convention.

	density	The logical density of the display. This is a factor that scales DIP (Density-Independent Pixel) units to the device's resolution. DIP is adjusted so that 1 DIP is equivalent to one pixel on a 160 pixel-per-inch display. For example, on a 160-dpi screen, density = 1.0, while on a 120-dpi screen, density = .75. The value does not exactly follow the real screen size, but is adjusted to conform to large changes in the display DPI. See density for more details.
am.current	package	The Android package name of the currently running package.	The am.current keys return information about the currently-running Activity.
	action	The current activity's action. This has the same format as the name attribute of the action element in a package manifest.
