Hello,
I'm experienced in many languages and platform including android, i'm fluently in graphic, video, socket programming in 9 years.
I think, the best solution for your project is:
- To display video post in list, should take first video frame to display in image view instead of videoView.
- To watch video in a post, should display only one VideoView as full screen like youtube.
I think it will be ok for all devices.
Thanks,
Binh
