Do not post the same question in more than one forum. It annoys people, and they won't answer your question.

I am new to Andriod Development, and i am using Eclipse java IDE.
i am having troubles when i edit any files. The application is working fine unless each time if you need to change in any of the layout files or manifiest. (baiscally the XML files) it always troubling me 
just generating a empty of the file name with an "out" extention. example main.out.xml.
then i have do delete the file and uload/load project manytimes and then it will come back to normal. this problem making me nurvois to change any files.

Hi,
at last i found the solutions in one of the forums
ye but its still a bug. pretty amazing this survived beta.
forums i read said you need to:
1) delete the main.out.xml file
2) close all layout files
3) select a .java file or the project node and then try to run
nup. Still didn't work. I finally found out, purely by accident, that you also need to delet the compoile error that appears under the problems tab.

Hi everyone,
I not really good with programming, so I need some help. Does anybody know how to create a stopwatch for an Android phone using Java programming? Thanks in advance.

You could store the System.currentTimeMillis() in a long upon a start button press to note the start time. When someone presses stop read the System.currentTimeMillis() again and substract the already stored value from the start. Now you are left with the amount of milli seconds that passed between the two events.

Hi,
I'm kinda new to programming and with not much knowledge on Java. But this is urgent!! I need help in research. I'm need to create a mobile application using Android and Eclipse.
Objectives:
To develop a mobile application that would be able to push help messages in the event whereby the mobile user requires assistance.
Scope of project:
Develop a mobile application that;
A module to detect movements
A decision making module with the intelligence to trigger an alert based on a set of rules
A module to push an alert message to a 3rd party e.g. via the SMS
Any ideas on how I should go about doing this? Thanks.
Best Regards,

Would you post the exception details? That will help to determine the issue.
|

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>

This is a discussion board for Mobile Programming questions. Unless you want to develope mobile applications for iPhone and wondering if you should go ahead and develope one for this chinese phone; you are in the wrong place.

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,
Peter

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.
