I want to export my design in dp but my all measurement are in points. I tried sending it to the developer but he was not happy. Is pt and dp same for icons and text? Can I send the point dimension for dp?
You probably should send your designs with pixel measurements because pixels are easier to convert to density independent pixels (dp). (Google Material on dps)
Conversion ratio from points to pixels may not be 1:1 as point length is depended on resolution. From Graphic Design Stack Exchange:
How many pixels = 1pt depends on the resolution of your image. If your image is 72ppi (pixels per inch), then one point will equal exactly one pixel.
