    /**

     * Indicates that usage of this API is limited to apps based on their target SDK version.

     *

     * Access to the API is allowed if the targetSdkVersion in the apps manifest is no greater than

     * this value. Access checks are performed at runtime.

     *

     * This is used to give app developers a grace period to migrate off a non-SDK interface. When

     * making Android version N, existing APIs can have a maxTargetSdk of N-1 added to them.

     * Developers must then migrate off the API when their app is updated in future, but it will

     * continue working in the meantime.

     *

     * Possible values are:

     * <ul>

     *     <li>

     *         {@link android.os.Build.VERSION_CODES#O} or {@link android.os.Build.VERSION_CODES#P},

     *         to limit access to apps targeting these SDKs (or earlier).

     *     </li>

     *     <li>

     *         absent (default value) - All apps can access this API, but doing so may result in

     *         warnings in the log, UI warnings (on developer builds) and/or strictmode violations.

     *         The API is likely to be further restricted in future.

     *     </li>

     *

     * </ul>

     *

     * Note, if this is set to {@link android.os.Build.VERSION_CODES#O}, apps targeting O

     * maintenance releases will also be allowed to use the API, and similarly for any future

     * maintenance releases of P.

     *

     * @return The maximum value for an apps targetSdkVersion in order to access this API.
