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.

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
