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`	`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` This field was deprecated in API level O. Use `getSerial()` instead.
`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

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
