| * <p>BuildCompat.isAtLeast*() can be changed by Android Release team, and once that is changed it |
| * may take weeks for that to propagate to stable/prerelease/experimental SDKs in Google3. Also it |
| * can be different in all these channels. This can cause random issues, especially with sidecars |
| * (i.e., the code running on R may not know that it runs on R). |
| * |
| * <p>This still should try using BuildCompat.isAtLeastR() as source of truth, but also checking |
| * for VERSION_SDK_INT and VERSION.CODENAME in case when BuildCompat implementation returned |
| * false. Note that both checks should be >= and not = to make sure that when Android version |
| * increases (i.e., from R to S), this does not stop working. |
| * |
| * <p>Supported configurations: |
| * |
| * <ul> |
| * <li>For current Android release: while new API is not finalized yet (CODENAME = |
| * "UpsideDownCake", SDK_INT = 33) |
| * <li>For current Android release: when new API is finalized (CODENAME = "REL", SDK_INT = 34) |
| * <li>For next Android release (CODENAME = "VanillaIceCream", SDK_INT = 35+) |
| * </ul> |
| * |
| * <p>Note that Build.VERSION_CODES.T cannot be used here until final SDK is available in all |
| * channels, because it is equal to Build.VERSION_CODES.CUR_DEVELOPMENT before API finalization. |
| * |
| * @return Whether the current OS version is higher or equal to U. |
