I Need tuts for creating simple java apps

I would advise caution with that approach....

If an end user finds themselves being redirected to a website, they'll most likely uninstall the app and leave you terrible reviews! You'd be better off integrating the data from the website into the app (updating the data whenever they open the app) and keep the users inside the app. However, this isn't just a trivial Java app - you'll need a good foundation in programming and design patterns to build something solid.

You might be better off posting your requirements on Elance or oDesk and have an experienced programmer build it for you, leaving you to handle the marketing and the money-making!

Hope that helps!

Derek Banas has an excellent tutorial series on Java itself- for Android development, I'd recommend watching the first 5 tutorials or so and then moving on to this next site.

Travis at The New Boston has a lengthy video series that's basically a video Android Cookbook, as he covers a lot of disjointed topics but gets to pretty much everything you need to develop for Android. He's very informal and likeable (if annoying at times, like when he says "for the most part" 6 times in a 7-minute video).

Finally, Android Cookbook: Home is great for a similar learning style (just learn what you need as you go along). It's from the O'Reilly series, I personally recommend buying the paper copy as it's a bit more thorough and I'm a big fan of paper references, but as far as digital learning resources go this one is solid.

What it sounds like you might be looking for is a WebView app, basically an Android app that runs in a browser environment on the client device. A great system utilizing the WebView is called PhoneGap, which lets you code in Javascript against the PhoneGap API, which provides access to a lot of native functionality for iOS and Android.
The Phonegap Build service is from Adobe, it's 100% free and pretty cool. I noticed that it didn't offer some of the specific features I was looking for for a few of my apps so I passed over it, but when I first found it I did try it out and found it a pretty cool experience to code Javascript and wind up with an app that just... worked. Very cool, worth a look (and definitely sounds like the easiest way for what you're trying to achieve in this instance). One drawback that a lot of people using PhoneGap have mentioned is that the apps run a bit slower than natively coded (Java + Android SDK) apps, and also lack the native feel. One would expect as much, but I found it to be pretty negligible in the playing around I did with PhoneGap.

Hope this helps, mate!
