android - JPEG Image Loading Slow Compared to Browser -
i making application displays jpeg images in grid
, listview
.
for example, 500x500, 640x640, 300x300 (various different sizes).
i have been struggling find way improve loading speed. have been using picasso, uil, volley library there wasn't significant change in speed (too slow).
i tried following test many times:
- all devices connected wi-fi, , images stored in web server.
- images in jpeg format, , file sizes between 150–250 kb each.
- desktop/laptop using internet browser load 10 550x550 images.
- android phone using internet browser (google chrome) load 10 550x550 images.
- android phone using application load 10 550x550 images
the result hilarious.
i typed same url show these 10 images; took around 2 seconds download , display images on browser (both on laptop , android device). it's taking each image 2-3 seconds display in application.
please provide advice on how improve speed.
