+## Auto cherry-pick in API_LEVEL
+
+If requested to port the commits from this PR on a dedicated _API_LEVEL_ branch,
+select the targeted one(s), or add new references if not listed:
+
+[ ] TARGET_API_LEVEL: API_LEVEL_24
+[ ] TARGET_API_LEVEL: API_LEVEL_25
+
+This will only create the PR with cherry-picks, ready to be reviewed and merged.
+
+Remember:
+
+- The merge will ALWAYS be a manual operation.
+- It is possible the cherry-picks don't apply correctly, mainly if previous commits have been forgotten.
+- In case of failure, there is no other solution than redo the operation manually...
