I am going to start a new app from scratch. It has high usage of images. Just wanted to know if bitmaps or svg images would be better to use in the app considering the performance of the application? I know svgs are independent of screen size and they can stretch according the screen size but i am going have only one resolution for the app i.e 360x640. If screen size is fixed, then do you think bitmaps are better to use than svgs?

Please suggest. I have not worked with svgs so far. If you think svgs are better in all situations, plz provide some links explaining usage of svgs in application views and as application icon as well.
