[android-developers] Re: Managing Large Graphic Set
I have taken a look at the google video about game programming for android, although I haven't had the time to watch it all of the way through yet, it seems like a great start. A big part of why i'm trying to do it, the way that i'm trying to do it, is because i'm trying to prevent the manipulation of the graphics from the client-side of the application (this is supposed to be a client/server type of game, although it is still pretty basic). Again, I would like some kind of package that included these for the most part, so I can do a simple md5/sha-1 checksum on 1 file, instead of each file, everytime the client loads. I appreciate all of the feedback thus far, as well. On Sep 14, 7:56 pm, Carmen Delessio carmendeles...@gmail.com wrote: That solves a few problems for me. Thanks.

[android-developers] Re: Managing Large Graphic Set
You can accelerate access to zip files by specifying a lower compression rate or no compression at all during creation of the archive. Keep in mind that you can also specify the compression rate for each file individually (See ZipOutputStream.setLevel()). It may also be interesting to compare the size and performance impact of the lowest- and highest compression rate. Just an idea, Michael. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Managing Large Graphic Set
For mobile, a 320x480 screen, why are the images so large? Perhaps you can optimize your graphics? PNG is a lossless format... great quality and transparany support... but do you need that? I don't know what you're developing for, but would another format work better? JPEG - smaller file size, but lossy compression GIF - lossless compression but only 256 colors Are the graphics resized properly? I remember when I was learning how to use Quark in school. Heh... large images with lots of extra white space. It made the printer angry. HEH... but then we got a new printer. Ah, the memories... anyway... There's a wonderful video that talks about graphics and games. http://www.youtube.com/watch?v=U4Bk5rmIpic I watched the whole thing... over an hour long... even replaying many parts because he talks so fast... excellent. Have you seen it? Heh... I wonder if he ever released the code for that game. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
