Research direction
Focus on understanding the shared element transition behavior in Android N (API 24) and how fresco handles it. Review the issue comments for any workarounds or reproduction steps. Check fresco's transition related code, possibly in DraweeViews or image pipelines. Investigate if it's a framework bug or a fresco specific workaround. Look at the linked pull requests or commits that attempted fixes.
