Creating java applications for Jeode - Windows Mobile Development and Hacking General

I have the jeode jvm for my xda exec and am hoping to develop for it. I transferred a few of my simple java j2se jar files but they dont work. How do I go about developing for jeode?
Thanks

JVM On XDA II After ROM Upgrade

Hi,
I heard that the XDA II supports Java after a ROM upgrade.
Could anybody tell me what kind of JVM that is and/or what kind of Java applications it supports (CLDC, MIDP 1.0/2.0, CDC, PersonalJava)?
Thanks in advance.
Regards,
Marvin
it's not a vm it's a midlet running
this thread have both the cab file for the midlet manager
and some info about installing javavm yourself like ewe

Thanks.

Question for developers

I want to learn how to develop small apps for the pocket pc platform.
What language should I learn. What software do u use?
Visual Basic? c++ ? I am kinda stuck.
Can someone point me in the right direction... also where can I find good documentation on developing for this platform?
Thanks
visual studio .net 2003 let you make applications for the xda in c++, c# and basic
embedded visual studio let you make applications for the xda in c++ using mfc and win32
you can also use powerbuilder i think it's called
and gc as in the gnu compiler
which language you want to use is up to you really
Hi,
i just decompressed a .cab file found in my MDA compact extended rom:
Default_PhonePad_ITA_RC10.CAB
i found a lot of files....
0CeSetup.001
0CeSetup.999
IN05D9~1.020
IN71C6~1.016
etc..
etc...
the question is easy...
how can i open these files? What kind of language are those files programmed with?
thanks in advance

they would be Binary files as in already compiled files you it matter not which language they are written in as when they are compiled they are nothing but 0's and 1's
how you open them really depend on what you mean by opening them
if you mean that you want to run the application then you should not extract the files just doubleclick on the cab file and it autoinstall
if you mean how you edit cab files then there are many cab file editors
try doing a search in the forum or on google
if you mean that you want to decompile them back to code then i'm sure there are tools for that too but code which have already been compiled and then taken back to code looks very very bad
and you need to really understand win32 sdk to understand much of whats going on
decompilers should be able to decompile to what ever langauge they support no matter which language the program originaly was written in
Additional Programs
For Cabs: use the WinCE CAB Manager, download here: sorry forgot the link, just search here.
For ms_.nbf: use the windows mobile 2003 ROM Editor, download here: http://forum.xda-developers.com/download.php?id=3208

Incorrect. Visual Studio.net 2003 lets you make c# questions for PocketPC, but nothing else. For C++ you needed embeddded visual studio.
Visual Studio.Net 2005 does add everything, but thats in beta.

yes, i meant this. Decompiling the cab file to read the code.
I thought there was a compiler for each language, that's why i was asking.
If somebody could suggest a free good decompiler....
well a cab file is not a program is more like a zip file
use the cab thingy mentioned and get the dll and exe files out of the cab file
here is what you would look for if the programs like most games is in pure ARM code
http://www.google.dk/search?q=arm+decompiler&btnG=Søg&hl=da
maybe this would help if you are trying to access .net
http://www.programmersheaven.com/search/download.asp?FileID=38892
how you go about it when you know something about the arm asm and maybe want to write your own decompiler
http://list.cs.brown.edu/pipermail/plt-scheme/2004-August/006284.html
maybe this

or if you feel luckey

cab
my apology...cab is not a program...

Getting started

Hi all,
I just bought an O2 XDA(ii). Regarding software development, what compiler is needed? I have Visual Studio 2003 and 2005, but isn't some sort of cross compiler needed for Windows Mobile?
Also, can the the .NET compact framework be installed on Windows Mobile? If so, will a Windows .NET app run on it?
Sorry for the basic questions, but one has to start somewhere!!
Thanks

In order to develop applications for pocket pcs, you need to download the sdks from Microsoft.
With VS2005 you can create .Net applications for pocket pcs and test them on an emulator or on the device directly.
There is a .Net framework installed on WM2005 pocket pcs.
Cheers,
.Fred
Excellent - thanks!

Programming Environment Please

Hi folks.
I'm a VB6 programmer and I have to develop an app for the XDA as part of a large project in which I am involved. I have read that embedded vb is available but could do with step by step directions to the essential tools necessary to allow vb6 development for this.
I can not seem to find a microsoft download for embedded VB6 though the C++ one is readily available and I have downloaded the pocket pc sdk. A little guidance would be most appreciated.
Many thanks

Doubts with Using Xamarin to develop Android App

Hi All,
We are developing Android App using C# with Xamarin.
I have task to integrate existing C source with App developed. This done by loading corresponding *.so.
Sorry in advance if these questions are naive....
Questions:
1 > I am using Windows. To generate the *.so what is the suitable IDE? Can the windows be used to generate *.so(static object)?
2> If I were to go with Eclipse , Do I need to install the plugins like SDK ,NDK etc...?
3> Do I need to care for processor architecture's , If need to compile the source?....I mean cross compilation
Thanks

I'm not sure if I understand you question but I assume you want to extend an existing app -build in C# using Xamarin- with native android Java?
I'm not sure that's even possible. Xamarin is utilizing mono for android to create android (Linux) executable files. When decompiling my own Xamarin build apk with APK Studio I did see the mono .so libraries, but my own code was compiled. Referenced .Net (Windows!) dll's where added to the apk. I assume the mono libraries deal with how they are used in the compiled C# code.
Since there's no quick conversion I see a few options:
A - Change the Xamarin/C# android project to a library project (dll). Compile it using Xamarin and find out (google) how to utilize this dll using mono for android in your Java development environment (eclipse). There are mono .so files...
B - Convert the Xamarin/C# source to java source code. There are some commercial tools which claim to be able to convert C# to Java. Go java all the way.
C - Stick to Xamarin/C#
I think option A will lead to lots of headache assuming you referenced some .Net assemblies in your C# source. However it might be worth a try. Though keep in mind that if you keep using the Xamarin/C# part, you keep needing the Xamarin license to upgrade/update code in the future.
I would go for either B or C depending on the codebase. If it's a lot of code a Xamarin license renewal might be cheaper then a rewrite (conversion). In my experience code converters are reasonable tools, but I've never saw a one-click conversion happen. There's always extra work to make the converted code even compile.
In conclusion: Mixing Xamarin/C# and native Java code might be technically possible, I would rather make a choice for either one of them.
I can't answer your questions about eclipse and required libraries, but I hope my answer is of some use.
Regards,
Alex
