Build

UNKNOWN

static val UNKNOWN: String

Value used for when a build property is unknown.

Value: "unknown"

getFingerprintedPartitions

open static fun getFingerprintedPartitions(): MutableList<Build.Partition!>

Get build information about partitions that have a separate fingerprint defined. The list includes partitions that are suitable candidates for over-the-air updates. This is not an exhaustive list of partitions on the device.

getRadioVersion

open static fun getRadioVersion(): String!

Returns the version string for the radio firmware. May return null (if, for instance, the radio is not currently on).

getSerial

open static fun getSerial(): String!

Gets the hardware serial number, if available.

Note: Root access may allow you to modify device identifiers, such as the hardware serial number. If you change these identifiers, you can not use key attestation to obtain proof of the device's original identifiers. KeyMint will reject an ID attestation request if the identifiers provided by the frameworks do not match the identifiers it was provisioned with.

Starting with API level 29, persistent device identifiers are guarded behind additional restrictions, and apps are recommended to use resettable identifiers (see Best practices for unique identifiers). This method can be invoked if one of the following requirements is met:

• If the calling app has been granted the READ_PRIVILEGED_PHONE_STATE permission; this is a privileged permission that can only be granted to apps preloaded on the device.
• If the calling app has carrier privileges (see android.telephony.TelephonyManager#hasCarrierPrivileges) on any active subscription.
• If the calling app is the default SMS role holder (see android.app.role.RoleManager#isRoleHeld(String)).
• If the calling app is the device owner of a fully-managed device, a profile owner of an organization-owned device, or their delegates (see android.app.admin.DevicePolicyManager#getEnrollmentSpecificId()).

If the calling app does not meet one of these requirements then this method will behave as follows:

• If the calling app's target SDK is API level 28 or lower and the app has the READ_PHONE_STATE permission then Build#UNKNOWN is returned.
• If the calling app's target SDK is API level 28 or lower and the app does not have the READ_PHONE_STATE permission, or if the calling app is targeting API level 29 or higher, then a SecurityException is thrown.

BOARD

static val BOARD: String!

The name of the underlying board, like "goldfish".

BOOTLOADER

static val BOOTLOADER: String!

The system bootloader version number.

BRAND

static val BRAND: String!

The consumer-visible brand with which the product/hardware will be associated, if any.

CPU_ABI

static val CPU_ABI: String!

Deprecated: Use SUPPORTED_ABIS instead.

The name of the instruction set (CPU type + ABI convention) of native code.

CPU_ABI2

static val CPU_ABI2: String!

Deprecated: Use SUPPORTED_ABIS instead.

The name of the second instruction set (CPU type + ABI convention) of native code.

DEVICE

static val DEVICE: String!

The name of the industrial design.

DISPLAY

static val DISPLAY: String!

A build ID string meant for displaying to the user

FINGERPRINT

static val FINGERPRINT: String!

A string that uniquely identifies this build. Do not attempt to parse this value.

HARDWARE

static val HARDWARE: String!

The name of the hardware (from the kernel command line or /proc).

HOST

static val HOST: String!

ID

static val ID: String!

Either a changelist number, or a label like "M4-rc20".

MANUFACTURER

static val MANUFACTURER: String!

The manufacturer of the product/hardware.

MODEL

static val MODEL: String!

The end-user-visible name for the end product.

ODM_SKU

static val ODM_SKU: String

The SKU of the device as set by the original design manufacturer (ODM).

This is a runtime-initialized property set during startup to configure device services. If no value is set, this is reported as UNKNOWN.

The ODM SKU may have multiple variants for the same system SKU in case a manufacturer produces variants of the same design. For example, the same build may be released with variations in physical keyboard and/or display hardware, each with a different ODM SKU.

PRODUCT

static val PRODUCT: String!

The name of the overall product.

RADIO

static val RADIO: String!

Deprecated: 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.

The radio firmware version number.

SERIAL

static val SERIAL: String!

Deprecated: Use getSerial() instead.

A hardware serial number, if available. Alphanumeric only, case-insensitive. This field is always set to Build#UNKNOWN.

SKU

static val SKU: String

The SKU of the hardware (from the kernel command line).

The SKU is reported by the bootloader to configure system software features. If no value is supplied by the bootloader, this is reported as UNKNOWN.

SOC_MANUFACTURER

static val SOC_MANUFACTURER: String

The manufacturer of the device's primary system-on-chip.

SOC_MODEL

static val SOC_MODEL: String

The model name of the device's primary system-on-chip.

SUPPORTED_32_BIT_ABIS

static val SUPPORTED_32_BIT_ABIS: Array<String!>!

An ordered list of 32 bit ABIs supported by this device. The most preferred ABI is the first element in the list. See SUPPORTED_ABIS and SUPPORTED_64_BIT_ABIS.

SUPPORTED_64_BIT_ABIS

static val SUPPORTED_64_BIT_ABIS: Array<String!>!

An ordered list of 64 bit ABIs supported by this device. The most preferred ABI is the first element in the list. See SUPPORTED_ABIS and SUPPORTED_32_BIT_ABIS.

SUPPORTED_ABIS

static val SUPPORTED_ABIS: Array<String!>!

An ordered list of ABIs supported by this device. The most preferred ABI is the first element in the list. See SUPPORTED_32_BIT_ABIS and SUPPORTED_64_BIT_ABIS.

TIME

static val TIME: Long

The time at which the build was produced, given in milliseconds since the UNIX epoch.

TYPE

static val TYPE: String!

The type of build, like "user" or "eng".

USER
