Various version strings.

Summary

Fields
`public static final String`	`BASE_OS` The base OS build the product is based on.
`public static final String`	`CODENAME` The current development codename, or the string "REL" if this is a release build.
`public static final String`	`INCREMENTAL` The internal value used by the underlying source control to represent this build.
`public static final int`	`PREVIEW_SDK_INT` The developer preview revision of a prerelease SDK.
`public static final String`	`RELEASE` The user-visible version string.
`public static final String`	`SDK` This field was deprecated in API level 4. Use `SDK_INT` to easily get this as an integer.
`public static final int`	`SDK_INT` The user-visible SDK version of the framework; its possible values are defined in `Build.VERSION_CODES`.
`public static final String`	`SECURITY_PATCH` The user-visible security patch level.

Public constructors
`Build.VERSION()`

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.

Fields

BASE_OS

Added in API level 23

String BASE_OS

The base OS build the product is based on.

CODENAME

Added in API level 4

String CODENAME

The current development codename, or the string "REL" if this is a release build.

INCREMENTAL

Added in API level 1

String INCREMENTAL

The internal value used by the underlying source control to represent this build. E.g., a perforce changelist number or a git hash.

PREVIEW_SDK_INT

Added in API level 23

int PREVIEW_SDK_INT

The developer preview revision of a prerelease SDK. This value will always be 0 on production platform builds/devices.

When this value is nonzero, any new API added since the last officially published API level is only guaranteed to be present on that specific preview revision. For example, an API Activity.fooBar() might be present in preview revision 1 but renamed or removed entirely in preview revision 2, which may cause an app attempting to call it to crash at runtime.

Experimental apps targeting preview APIs should check this value for equality (==) with the preview SDK revision they were built for before using any prerelease platform APIs. Apps that detect a preview SDK revision other than the specific one they expect should fall back to using APIs from the previously published API level only to avoid unwanted runtime exceptions.

RELEASE

Added in API level 1

String RELEASE

The user-visible version string. E.g., "1.0" or "3.4b5".

SDK

Added in API level 1

String SDK

This field was deprecated in API level 4.
Use SDK_INT to easily get this as an integer.

The user-visible SDK version of the framework in its raw String representation; use SDK_INT instead.

SDK_INT

Added in API level 4

int SDK_INT

The user-visible SDK version of the framework; its possible values are defined in Build.VERSION_CODES.

SECURITY_PATCH

Added in API level 23

String SECURITY_PATCH

The user-visible security patch level.
