问题 I want to save image using my developed app into mobile what is the best way to it. I was trying to save via sqlite but is there any other options? 回答1: The recommended way is to store the image as a file not in the database and then store the path or enough of the path to uniquely identify the image in the database.

问题 I'm showing 96x96 pixel art sprites in imageviews and can't get it to display without applying anti-aliasing (or at least some form of interpolation, if it isn't anti-aliasing), which ruins the sharp edge of the sprites. How can this be done? I've tried the following methods I've picked up from around the internet, but none work.
