| /** |
| * Indicates than an API is only supported on platform versions of at least the given value and |
| * later. |
| * |
| * Currently, this annotations is purely informational. The exact meaning of this annotation depends |
| * on it's context: |
| * <ul> |
| * <li>On a public SDK method, it means that the member should only be included in the SDK of |
| * the given version or later</li> |
| * <li>On a module API, it will mean that it should only be called when running on a device with |
| * the given SDK or later</li> |
| * </ul> |
| * |
| * In future, the annotation will acquire further semantics: |
| * <ul> |
| * <li>Classes annotated with this will only be classloaded on devices running the given SDK |
| * version or later.</li> |
| * <li>It will be used to ensure API safety at build time in the context of a codebase with |
| * different parts having different min SDK versions.</li> |
| * </ul> |
| * |
| * This annotation should only be used on code that exports an API (either public SDK or |
| * {@code @SystemApi}. For code that just calls APIs that only exist on newer platform versions |
| * use {@code androidx.annotation.RequiresApi} instead. |
