offlnie webapps

I'm not sure why this works on the KIN (because it doesn't work on the wp7), but it does. The browser on the KIN supports the HTML5 cache manifest command, info here (http://en.wikipedia.org/wiki/The_cac...ifest_in_HTML5). To prove this here is a working offline tetris game I have on my KIN (tetris.alexkessinger.net), the only problem is I can't actually play it because there are no arrow keys on the phone, but it is fully functioning (I get to watch the pieces fall).

So here is my idea... I see we do have developers in this forum so maybe they can try to either create some javascript webapps designed to run on the KIN that use the manifest to cache the needed files.

OR maybe we could use the cache manifest to cache an executable file and then have that filed executed through another website that gives the command to run it. I'm sure that is just wishful thinking and more than likely won't work, but I thought I would throw that out there.

Nice suggestion, but unfortunately it will not work. Just because the game is available offline doesn't mean the browser supports the HTML5 cache manifest. Pretty well every browser that I know of does and always has had a cache to store some webpage files. The KIN browser is no different. The KIN is just storing the javascript from that webpage in the cache. The tetris game is not the type of web application the HTML5 cache manifest wiki describes. Furthermore, to cache anything from the KIN browser, the 'anything' must be supported by the browser--such as the javascript used to run the tetris game. Executable files are not supported by the KIN browser.

Thanks

Thanks for clearing that up for me, like I've said before I'm not a programmer (at least not in the last 10 years). However, this game is successfully cached and able to run hours after visiting the page. So maybe there is a way to duplicate it so that other javascript games can be made available to use offline. I just don't know how this game is caching the coding along with the images needed to run it. I thought it was the cache manifest because when I view the page source it says "<html manifest="tetris.manifest">".

Let me know your thoughts, I plan to try and duplicate it next week with a blackjack game, but I am in the middle of finals so I don't have time until the middle of next week. Also, like I said I'm not a programmer so I will be trying to reteach myself, so it's gonna take a while and probably not work.

I may have posted the wrong wiki link, but the cache manifest comand does work. Below is a link to a game, with needed images, that will cahe on the phone. it is available around 12 hours after opening it. So if you put it as an "app" it is almost the same thing. Just visit it before you leave wifi and youll be good until you are in wifi again.

It was a worthy try, man, but that link is to an address on your local network. Do you have someone on the internet we can access? Or can you port forward port 80 through your router, to that system, to allow external access?

It is a router problem. I tried to open port 80 last night, but it still is not working. I am going to play with it some and see if it is a firewall problem OR if I just messed up when setting up the port forwarding. Sorry, like I've said I am not an expert.

It's a bad address, cause he's giving out the LAN address asigned by the router.

For you to be able to use it, you would need to be in his lan or in an VPN to his lan.

To real test what you got externaly, you need to give the external (to world) ip which is given by your own router admin panel, and/or websites like whatismyip.com.
then you need to do Nat from your external Ip to your local ip, specifying so in the router.

Or else, just share the website in a zip, and save time to do stuff like eat an ice cream, drink a soda/beer and have fun.

Thanks John

Thanks for the advice because this was my first time trying to make it available to everyone and clearly I couldn't do it. However, here is the file folder below. I have also done a couple of simple java apps that don't have any images (tic tac toe, blackjack, and the scientific calculator that was created by gsearle) I didn't include any of them because this bubbles one has images and shows the cache manifest works better. Also I don't have gsearle's permission so I wouldn't redistribute his work.
