Fields

public static final String BASE_OS

Added in API level 23

The base OS build the product is based on.

public static final String CODENAME

Added in API level 4

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

public static final String INCREMENTAL

Added in API level 1

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

public static final int PREVIEW_SDK_INT

Added in API level 23

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.

public static final String RELEASE

Added in API level 1

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

public static final String SDK

Added in API level 1

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.

public static final int SDK_INT

Added in API level 4

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

public static final String SECURITY_PATCH

Added in API level 23

The user-visible security patch level.
