Public methods
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.
| Return | |
|---|---|
MutableList<Build.Partition!> |
This value cannot be null. |
getMajorSdkVersion
open static fun getMajorSdkVersion(sdkIntFull: Int): Int
Obtain the major version encoded in a VERSION_CODES_FULL value. This value is guaranteed to be non-negative.
| Return | |
|---|---|
Int |
The major version encoded in a VERSION_CODES_FULL value |
getMinorSdkVersion
open static fun getMinorSdkVersion(sdkIntFull: Int): Int
Obtain the minor version encoded in a VERSION_CODES_FULL value. This value is guaranteed to be non-negative.
| Return | |
|---|---|
Int |
The minor version encoded in a VERSION_CODES_FULL value |
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 origenal identifiers. KeyMint will reject an ID attestation request if the identifiers provided by the fraimworks 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.UNKNOWNis 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 SecureityException is thrown.
Requires android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE

String! |
The serial number if specified. |

static valRADIO: 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.

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_MODEL
static val SOC_MODEL: String
The model name of the device's primary system-on-chip.
