I want to achieve this type of design : http://i.imgur.com/APi1p8N.png
So I want to use vector instead of PNG for scalability, but will this make my app slower ? Should I use multiple PNG instead ? (I will not have gradients because it's not supported before API24 and seems to request a lot of resources.)
What do you think, SVG or PNG for this type of design ?
Thanks a lot,
