ApiVersion

public abstract class ApiVersion
extends Object

java.lang.Object
↳	android.car.ApiVersion<T extends android.car.ApiVersion<?>>

Known direct subclasses

CarVersion, PlatformVersion

CarVersion	Represents the API version of the `Car` SDK.
PlatformVersion	Represents the API version of the standard Android SDK.

Abstraction of Android APIs.

This class is used to represent a pair of major / minor API versions: the "major" version represents a "traditional" Android SDK release, while the "minor" is used to indicate incremental releases for that major.

This class is needed because the standard Android SDK API versioning only supports major releases, but Car APIs can now (starting on Android 13) be updated on minor releases as well.

Summary

Public methods
`final int`	`getMajorVersion()` Gets the major version of the API represented by this object.
`final int`	`getMinorVersion()` Gets the minor version change of API for the same `getMajorVersion()`.
`final boolean`	`isAtLeast(T requiredVersion)` Checks if this API version meets the required version.

Public methods

getMajorVersion

public final int getMajorVersion ()

Gets the major version of the API represented by this object.

Returns
`int`

getMinorVersion

public final int getMinorVersion ()

Gets the minor version change of API for the same getMajorVersion().

It will reset to 0 whenever getMajorVersion() is updated and will increase by 1 if car builtin or other car platform part is changed with the same getMajorVersion().

Client should check this version to use APIs which were added in a minor-only version update.

Returns
`int`

isAtLeast

public final boolean isAtLeast (T requiredVersion)

Checks if this API version meets the required version.

Parameters
`requiredVersion`	`T`: required major and minor version number

Returns
`boolean`	`true` if the `major version` is newer than the `requiredVersion`'s major or if the `major version` is the same as `requiredVersion`'s major with the `minor version` the same or newer than `requiredVersion`'s minor

Throws
`IllegalArgumentException`	if `requiredVersion` is not an instance of the same class as this object
