Build

public class Build
extends Object

java.lang.Object
   ↳ android.os.Build


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

This field was deprecated in API level 21. Use SUPPORTED_ABIS instead.

public static final String CPU_ABI2

This field was deprecated in API level 21. Use SUPPORTED_ABIS instead.

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[] SUPPORTED_32_BIT_ABIS

An ordered list of 32 bit ABIs supported by this device.

public static final String[] SUPPORTED_64_BIT_ABIS

An ordered list of 64 bit ABIs supported by this device.

public static final String[] SUPPORTED_ABIS

An ordered list of ABIs supported by this device.

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

Public constructors

Build()

Public methods

static String getRadioVersion()

Returns the version string for the radio firmware.
