What libraries improve smooth scrolling and image loading on midrange Android?

[Alexander.M]

I'm an Android developer working on a media-heavy application that's experiencing significant jank and occasional ANRs during complex list scrolling and image loading, particularly on mid-range devices. I've profiled with Systrace and identified some UI thread bottlenecks, but I'm struggling to prioritize the most impactful optimizations. For developers who have tackled similar performance issues, what specific strategies or libraries for efficient image loading, view recycling, or background task management yielded the biggest improvements in perceived smoothness and responsiveness for your users?
