In Java, what would the best way be to have a constantly listening port open, and still send upon receipt of a packet. I'm not particularly savvy with network programming at the moment, so the tutorials I've found on the net aren't particularly helpful. Would it make sense to have the listening socket as a serversocket and run it in a s...
Have any well-documented or open source projects targeted iPhone, Blackberry, and Android? Are there other platforms which are better-suited to such an endeavor? Note that I am particularly asking about client-side software, not web apps, though any information about the difficulties of using web apps across multiple mobile platforms is ...

I want to use a specific foreign language font for a Blackberry application. How is such a font created and loaded onto the Blackberry device? For example: ਪੰਜਾਬੀ ...
I've recently started developing applications for the Blackberry. Consequently, I've had to jump to Java and learn that and its associated tools. The syntax is easy, but I keep having issues with various gotchas and the environment. For instance, something that surprised me and wasted a lot of time is absence of real properties on a...
We have a rather simple site (minimal JS) with plain html and CSS. It is a simple mobile interface for our main application. We are running into trouble because we have more than one column and several browsers seem to force single columns. Through some searching I ran into 2 meta tags. <meta name="MobileOptimized" content="220" /> <...
We've all heard of successes by small-time software developers on the iPhone App store. Has anyone actually had success selling applications in the Blackberry ...
Every indication I have, based on my experience in embedded computing is that doing something like this would require expensive equipment to get access to the platform (ICE debuggers, JTAG probes, I2C programmers, etc, etc), but I've always wondered if some ambitious hacker out there has found a way to load native code on a Blackberry de...
I have just started authoring web pages for use on "smart phones". I need to target Blackberry, WinCE, iPhone, etc. What resources or books would you recommend for someone with ample web and software development experience but no experience developing UI for these devices? What emulation kits would you recommend, and how accurately do...

Has anyone researched how to access the gps chipset on a blackberry over usb so that it is unnecessary to transmit this data over the cell carrier's data network? Is it possible to access the GPS chipset, store information in a buffer, and open an interface connection (over the usb charging port), for access? Not sure if J2ME allows f...
if a mobile application needs to get data from multiple servers, is it better to call each server from the mobile device, or call one server which then talks to all the other servers? "should synchronization be initiated by the server or the mobile client?" to what degree does client do the book keeping. Say if the application is mob...
I've got a small little page that is going to be viewed from a BB. Here's my 2 questions: If I "click" on the link to submit the page, I get the following error: "JavaScript: An error occurred while executing a script." I can tell my BB to emulate a Microsoft IE browser and I don't get this error. I hope to not use this option because ...
I'm trying to access an internal website that requires windows authentication. I've tried going to the website on my Blackberry but get the following error: You are not authorized to view this page. You do not have permission to view this directory or page using the credentials that you supplied because your web browser ...
I'm writing an app for Blackberry that was originally implemented in standard J2ME. The network connection was done using Connector.open("socket://...:80/...") instead of http:// Now, I've implemented the connection using both methods, and it seems like some times, the socket method is more responsive, and some times it doesn't work at...
Is it possible to get a device to open a file on disk using the MIDlet.platformRequest(String url) method? I was hoping to use the following: midlet.platformRequest("file:///path/to/file/file.png"); But this just throws a ConnectionNotFound exception. I'm specifically using the BlackBerry platform, but I do not have access to the prop...
I would like to begin developing for the Blackberry platform and, specifically, the Bold and also the Storm device which is coming out soon. Do I need to get into Java and J2ME or can I develop sites in ASP.NET and just keep utilizing the skills I already have? I am completely new to mobile platform development and have no idea what it...
i need to to some (technically awful but still good looking) table designs for blackberries that have all css support disabled. i don't seem to find out how to get my links to display as follows without css: <style type="text/css"> a.hover { border:0; } a { text-decoration: none; } </style> is it even possible, just using html?...
The BlackBerry Desktop API has the interface IRimTable which apparently maps an "application database" on a BlackBerry device to a virtual structure (i.e, IRimTable has IRimRecords, each of which has IRimField) that developer can browse the handheld device data when it is connected to a desktop computer. Meanwhile, applications in the ...
Hi guys, I'm trying to programmatically reject a call on a BlackBerry, with Java + JDE. I'm intercepting the callIncoming event, and in there I need to do something to reject a call from a specific number. Does anyone know how to do that? Thanks. ...
