android photosphere or panorama view with hotspots

I want a activity that starts a photosphere or a panorama 360 loop view where i can add hotspots. Those hotspots will be kind circular image buttons that can collapse or uncollapse to show extra information like a list of 3 items.. always on that hotspot. Should be possible to click on that information to open new activity. UI of those hotspots and list I will do for myself I don't want UNITY project since i want to add that code in my actual application and I don't have knowledge of Unity. I tried scroll view horizontal.. but 1.- don't know how to load high quality pictures 2.- don't know how to do a loop to have a panorama experience 360. Thank you very much Jordi
