Class Overview

Information about the current build, extracted from system properties.

Summary

Nested Classes
class Build.VERSION Various version strings. 
class Build.VERSION_CODES Enumeration of the currently known SDK version codes. 
Constants
String UNKNOWN Value used for when a build property is unknown.
Fields
public static final String BOARD The name of the underlying board, like "goldfish".
public static final String BOOTLOADER The system bootloader version number.
public static final String BRAND The consumer-visible brand with which the product/hardware will be associated, if any.
public static final String CPU_ABI The name of the instruction set (CPU type + ABI convention) of native code.
public static final String CPU_ABI2 The name of the second instruction set (CPU type + ABI convention) of native code.
public static final String DEVICE The name of the industrial design.
public static final String DISPLAY A build ID string meant for displaying to the user
public static final String FINGERPRINT A string that uniquely identifies this build.
public static final String HARDWARE The name of the hardware (from the kernel command line or /proc).
public static final String HOST
public static final String ID Either a changelist number, or a label like "M4-rc20".
public static final String MANUFACTURER The manufacturer of the product/hardware.
public static final String MODEL The end-user-visible name for the end product.
public static final String PRODUCT The name of the overall product.
public static final String RADIO This field was deprecated in API level 14. The radio firmware version is frequently not available when this class is initialized, leading to a blank or "unknown" value for this string. Use getRadioVersion() instead.
public static final String SERIAL A hardware serial number, if available.
public static final String TAGS Comma-separated tags describing the build, like "unsigned,debug".
public static final long TIME
public static final String TYPE The type of build, like "user" or "eng".
public static final String USER
