please clear your question to justify it
what is error in this code and what about exception. Mention it
then we can solved it.

What are my options for creating websites for mobile?
What is WAP? Or use ASP.net to sniff which browser the request came from?

Hello
Use standard ASP.NET website project for creating mobile website. Important thing here is to detect request, if it is from mobile device than redirect user to mobile compatible pages instead of standard website.
For accurate and easy mobile device detection use http://51degrees.codeplex.com[^] It is an ASP.NET open source module which detects mobile devices and provides auto redirection to mobile optimized pages when request is coming from mobile device. It makes use of WURFL mobile device database.
Sample web.config configuration for redirecting users to different mobile pages based on MobileDeviceManufacturer property. You can create your own custom rules for redirection based on other mobile properties.
<redirect firstRequestOnly="false"
mobileHomePageUrl="~/Mobile/Default.aspx"
timeout="20"
devicesFile="~/App_Data/Devices.dat"
mobilePagesRegex="/(Apple|RIM|Nokia|Mobile)/">
<locations>
<location url="~/Apple/Default.aspx">
<add property="MobileDeviceManufacturer" matchExpression="Apple"/>
</location>
<location url="~/RIM/Default.aspx">
<add property="MobileDeviceManufacturer" matchExpression="RIM"/>
</location>
<location url="~/Nokia/Default.aspx">
<add property="MobileDeviceManufacturer" matchExpression="Nokia"/>
</location>
</locations>

I've wanted to get into development for smart phones, but the phones/plans are all so insanely expensive (at least in the US), I can't even come close to affording one right now. Not to mention multi-platform development.
I was wondering, is a phone absolutely necessary? How accurate are the emulators compared to the real thing? Is it possible to make apps without ever testing them on an actual device? I'm mainly interested in the Android and WP7 emulators.
Any info/advice would be greatly appreciated. 
Thanks...

I haven't done any Android dev (yet) or WP7 (probably never), but I have used at least 5 of the J2ME emulators from various manufacturers. My experience with them is that they each have a different set of bugs from the real phones. In that world, you can go a fair way on one or more emulators, but your final tweaking will almost certainly need a real phone.
Cheers,

I have an android phone, (droid2 running on froyo) and i also use the emulator. in my experience, the emulator is harder to work with simply because it takes up 90% of your system resources no matter how amazing your computer is. but as far as i have seen, as long as you don't want to use the sensors(orientation/compass, or accelerometer)much, it works about the same...

The WP7 emulator is actually quite good. Service calls, Push Notifications, local storage, 3D graphics, etc all work well.
There are some obvious things you can't do, like get GPS data, but in general there isn't much you can't do in the emulator.
Performance testing should certainly be done on actual hardware of course.

Yes, before releasing any application, you'll need actual hardware.
Alexander DiMauro wrote: How accurate are the emulators compared to the real thing?
Not bad, but there are quirks in every Windows emulator I have used. You can code around them, only to find the problem doesn't exist on the actual device.
Alexander DiMauro wrote: Is it possible to make apps without ever testing them on an actual device?
Well, yes, but I wouldn't. Depends on what type of apps and actually what you mean by apps. Full blown, large GUI apps, nope. Minimal GUI, large computational, you could give it a shot.
Any hardware-specific functionality will require two versions of the code - one to run in the emulator and one to run on the actual device (
if #DEBUG 
I spoke to the local AT&T rep for some used, "demo" devices. He said they couldn't supply them, but all of their trade-ins went to a specific company (regional, I believe), and he suggested contacting them for used units at a good price. I haven't done it yet, however. Also, if the app does not use the cell-phone capabilities, it is verrrry expensive to get a device without committing to a monthly data plan.
One other "gotcha" with development on the real device. When running in debug mode on the device, the PC (debugger) must be connected to the device. This usually means the device is docked in a cradle (although you may get away with a wireless connection). Take the device out of the cradle, and you lost the connection to the debugger. If the device requires using any buttons or ports that are not accessible when in the dock, you'll find yourself looking in the Digi-Keytm catalog for parts to build a cable to attach the device to the dock. Plaster of Paris works wonders to pour around the cable connector for a phone-shaped mold.
Example - in developing a voice recognition application using a headset, the headset plug was next to the docking port. Couldn't have the headset plugged in while in the dock, so a DIY cable was necessary.
Best of luck.

I'm not even sure which response to reply to. All good answers, thanks.
I guess the general consensus is that I can use the emulators to learn, but to actually package something and sell it, I need a phone. So...my mobile ambitions will be on hold for a while, I guess. 
The whole system seems pretty messed up for developers, at least in the US. I heard that in other countries there are no long term contracts? Is this true? The only way to afford a phone here is to get stuck in a 2-year contract.
Oh well. Thanks again for all the responses. I guess I'll just play with the emulators for a while.

Well, I know that Virgin Mobile has fairly cheap ($25 USD) data plans; if all you want is to do Android devleopment, that's the direction I would go. A decent phone is about $250 USD, but you're not locked into that long term contract. IIRC, for $25/month you get unlimited data and 300 minutes of voice. $60 buys you unlimited everything.

That looks pretty good. I might wait a little bit until they upgrade to Android 2.2. Thanks for the tip. That sounds MUCH better than getting stuck in another 2-year plan.

Coincidentally i created my first Android app yesterday.
It was, of course, a 'Hello World'-app.
I tested it on an emulator running froyo, and it did what one would expect from a hello world app.
Of course i wanted to show this amazing feat of technology to my collegues next morning, so i packaged it and installed it on my own Samsung galaxy S, running Froyo.
As I already feared the app had gotten an extra feature on my phone. Causing a 'Force Close' right away when you run it.
So no, in my little bit of experience, it seems the emulator isn't good enough as only testing device.
(And yes, I'm enormously proud of being the first person ever to make a Hello World-app fail! =D

Mine didn't fail. I never got it to compile.
Is this a different line?

My experience with iOS, RIM and Android devices indicates, yes you will need to test on the devices.
Example - We recently changed our app for RIM to be compatible with several new devices. I made changes to the screen layouts so that all looked pretty in the simulators.
When we installed and tested on the devices, text and images landed in different places on the screen. We went back made changes and they looked like crap in the simulators. Installed on the devices and TaDa! They looked great. Go figure.
We also stumbled upon an error in the RIM OS that doesn't show up in the simulator for a particular device. It is only shows up on the actual device itself.
So the moral of my story here is: Test on the device you say you are compatible with.

Yes, that seems to be the consensus here. So basically, unless you can afford to buy multiple phones with multiple data plans, you're pretty much stuck writing for just one platform.
Seems like a step backward, no? I love the fact that I can dual boot Windows 7 + Linux Mint on all my computers, and do work in multiple platforms very easily. It would be AMAZING if dual booting phones was possible!

In the very early days of WinCE (about a decade ago), there were multiple projects to make WinCE be a boot-loader for Linux. Booting into Linux then removing itself.
Not quite dual-boot, but fun...

You need very big budget to get every possible device to try on and make sure your app works.
There is always another option: Ask for a helping hand from buddys (pals) in CodeProject. If you have some doubts about code leaking to the wrong hands - just make it time-limited or other limited in other ways.
I have Samsung Galaxy Portal (Android 2.1). Thinking to get something bigger like WeTab or Dell Streak.
Other might have other devices, like Droid (w/ Froyo), HTC Desire, Google, HTC Legend and so on.
If you planing to make your application for only one device and software is proprietary to the company/project and no sharing is allowed (my case) - then you have no other choice but to get that device.
Whichever the case - I'm more that happy to help fellow programmer by loading software on the phone and writing report on it. Even simple "Yep, It works.." or "Nope, fatal disaster." sometimes is helpful.
The most important part - enjoy your path to enlightenment. Nothing can beat real sense of achievement.
