[android-developers] Re: PNG quality in WebView based app

I experienced the same problem, but in my case I don't load the the
image remotely. I load the image locally from the sd card. The
original image is very clear and uncompressed. I tried different
formats as well (png, jpg).
The only solution I found was to divide the large image into multiple
tiles and put them back together via html, then load the html file
locally. That's the only way the images don't get blurry when zooming
in.
