Spherical photo camera app > restart - Java for Android App Development

hi all
i've just installed the photosphere camera app for my GT-I9505 and i've sadly discovered that its still have the same old bugs from like 1 years ago!!
why this happen?? it is a good idea the photosphere, but it never get improved since its original apk!!
still sucks: bad alignment, and bad managing of shoots... and it completely dont use the compass, making me sometimes turn around for 360 degree while the app is still at like 300 or 400 degree... i mean WTF just fix it!.. google developers...:silly: (joking)
btw, here i am to try start developing a new app:
my first idea is to create a simple viewer with sphere ("mesh") that is maintained aligned to the real world xyz by using accelerometer, gyroscope and compass sensors...
the enviroment then should be able to access to the camera sensor... in a basilar way... for the start (no hdr, iso, exposure etc... )
i'm new in programming, i've read that there are more ways to create apps for android....
which is the best? ( < lame question )
there are prebuild programs with tools to make apps;
there is java;
there is C++; (or basic?)
how should i start? any ideas? suggestion?
someone want to cooperate?
thanks already for everything and sorry for my bad english ...

Short answer - only Java. Forget anything else. C/C++ is intented for coding CPU demanding pieces of code. Without Java you're limited to very basic set of API tools that won't create a real Android application (although it is absolutely doable)... Unless you can find a language that gets compiled to Dalvik bytecode and is able to import Android libraties (that are wiritten in Java and compiled into Dalvik)! There are a few exotic languages that can do that:
Scala
C# (named dot42)
C-to-Dalvik https://github.com/fillipejsilva/C-to-Dalvik-Compiler
Kawa (kind of Scheme) http://www.gnu.org/software/kawa/
Mirah (which is Ruby compiled to Dalvik)
Clojure http://www.deepbluelambda.org/programming/clojure/

Favourite application framework - Win32, ATL, MFC or .NET?

Hello developers,
What is your favorite application and GUI framework for Windows Mobile development? I have played a little with different options, and I'd like to get your opinion on it as well.
As far as I can tell, here are the options:
Win32:
+: Small executable files, small memory footprint, very fast startup
-: Archaic and terrible API. Not object-oriented. A pain to work with
ATL:
+: Same as Win32: small files, small footprint and very fast startup. Object-oriented-ish Win32 wrapper
-: Not too well documented. Seems to be more targeted towards making redistributable GUI components. Almost as painful as Win32
MFC:
+: Extensive object-oriented API. Provides a better UI framework than Win32.
-: Big and bloated. Executables get bigger than with Win32 and ATL. Although it's designed to be oo, it's still archaic and rather painful.
.NET:
+: Modern, well-design and well-documented API. Lowest development time. The assemblies can be ran and unit-tested on the PC during development.
-: Depends on the .NET runtime to be loaded, and startup time is therefore at minimum 2 seconds. No or poor access to hardware-near features like DirectDraw.
Do not forget Wrapper Libraries around win32.
Like PPL: www.arianesoft.ca.
Nor java, for that matter
In any case, it really depends on what you want to do. I've actually used a combination of all three "main" environments (that is, ATL is taken out of the equation... It's really an old one which should NOT be used for new development).
Oh, and native functions can be called from .NET too, just like you'd do a pinvoke on any win9x dll.

Thanks, I didn't know about PPL. I'll have a closer look on that one.
I know that native functions can be called using PInvoke. I've been using that for simple things like playing sounds. However, as far as I have understood, it's not possible to use for example DirectDraw in your own custom GUI components.
Have you actually used Win32 AND .NET in the same project? I thought interop was impossible on mobile devices?

Well, i'm not so sure it's "impossible". I actually agree it would be pointless (too slow to be of any use): just find a good pocket PC native engine (I don't have any link atm).

While the API itself isn't OO, but your app using it can be such
ATL & MFC: I wouldn't touch them even with a looong stick
.NET:
You're right, it gives you a nice API, but at the costs.
Generally, you should choose your way with every app you're starting with - the choice should be dependent on what your project is for.
I have to disagree with jahnotto on the original assessment:
Win32: First there is nothing "archaic" about it. These are pure APIs that give you full access to your system so as long as you are using Win32 OS you have to go through them one way or the other. It is C++ language that provides object orientation support and there is noting stopping you from creating your own classes that take full use of the API.
(Yes this is my favorite method of developing because it is gives you the fastest and cleanest binaries)
ATL: I heard good things about it, but did not get the chance to use it. However, it is just pre-written code. You are still writing using Win32 but some nice people went and coded some classes in advance for you.
Thats the one and only difference between it and "pure Win32".
MFC: Its very similar to ATL - just a bunch of classes that wrap APIs but its much balkier and poorly documented. It is useful if you need to make some quick tool with little code and a single dialog but not something you want to use for a serious program.
.NET: Here is my biggest disagreement with the thread starter - simply because he sees a positive side to it
Yes, .NET saves time for development but:
- Running .NET app on PC without emulator though possible will not give you proper indication of how this app will function on a PPC so its pointless.
- Because it need the .NET CF it takes a lot more memory then it should when running.
-The poor access is not only to "hardware near" features. You can't even make simple things like today plugins, keyboards or control panel applets without using native code components.
- I have yet to see a "well documented" MS product.
In short my general opinion on the .NET is that the devices are just not powerful enough yet to allow such wasteful programs plus they severely limit the developer on what parts of the device / OS he can utilize control.

Getting into WM5/WM6 programming?

I am interested in dabbling a little in programming for my Kaiser. I have programming experience, mainly php / mysql, though I have done some C and lots of scripting in my time. My biggest project so far though was an open source google maps mod to put on your website - thousands of lines of php / js code, mysql backend and AJAX tieing it together, some graphics routines etc, so I am no drooling n00b when it comes to coding.
How easy is it to develop basic stuff in WM?
I have access to MSDN, so I can get Visual Studio (2005 for sure, maybe later versions), so I think I have access to the apps I would need. I just ordered some books to help me along, but was wondering if I would likely face a steep learning curve.
All the stuff I want to do is today screen plugins - was thinking of having a bash at writing my own quick contacts plugin - *very* basic - just a vertically scrolling list of names over a transparent PNG button with maybe photos from the address book - I want it to be able to scroll by vertical gesture within an ultimatelaunch tab - is this likely to be quite easy and quite a good "first app" to program?
I was also looking at writing a lite repacement for phoneweaver as the only feature I use is to turn on BT when it detects power but no activesync (ie auto turn on BlueTooth when I am in the car and the device is cradled) - maybe a hack to force the keyboard backlight on in the same situation.

Comments / suggestions?
I would also be very interested in a thread or good reference on how to start to program app for mobile gadgets. Actually i'm a Delphi coder, and i would like to implement some applications on WM platform, but when i search over internet there's plenty of information, but no usefull information with "real-life" recomendations.
depend on the platform and language one wish to use really
there is c#.net, vb.net c++.net
c++ miniMFC, c++ PureWin32 sdk
oldVB

about delphi i dont know if anybody got some info i would say borlands site
Thanks rud. I was aware of various other posts, but my question was more of a "How steep is the learning curve?" rather than "How do you do it?".
There was also an element of "How do you do it?" insofar as there seem to be better or worse ways of going about various kinds of app (eg today apps with gesture support) which I am finding a bit of a minefield, but I feel that the new post was valid because I am giving an indication of my experience level and what I am trying to acheive - none of the posts you listed cover the combination of stuff I am trying to do. Reqs like pulling from outlook db and allowing gesture scrolling in a today plugin, I dunno, I may waste ages with C#, for example, only to realise it is a breeze with C++... I also note that a google search for wm programming gesture scroll today screen currently ranks this very thread #5. By tomorrow that'll be a googlewhack then.
Yes, there are various posts about how to get started, but I think maybe a sticky would be in order with a bit of info on the various paths - the vb/c++/c# options are quite bewildering - stuff like

Your question is mainly a matter of personal preference.
Here is my opinion on C++ vs. C#:
C++ advantages:
- Native code is faster than .NET
- Easier access to Win32 APIs
- Ability to write system components like keyboards and today plugins.
C# advantages:
- Saves on coding time
- Allows use of many .NET CF components to quickly accomplish complex tasks.
Please note that I am bias. I hate .NET and want nothing to o with it. Specially on mobile devices that do not have the processing power to spare for the .NET overhead.

is really useful, maybe if it were expanded upon, info such as for this route you need visual studio, etc, etc it would make a really good sticky for the dev section.

Hey!
Congrats on getting your hands on with Windows Mobile...
The easiest way is to download Visual Studio 2005(2008 You have it on MSDN) - and create a new application with it.
It's sooo easy if you know your object oriented programming, as long as you want to create ordinary "office" applications... But if you want to do more advanced things(like creating a today-plugin) you need to go over to c++(even though you can download a .net home-plugin-container which acts like a "loader" for your plugin written in c++) - and also, if you want to create good GUIs, I think you are better off with c++... But then again, I think you need a bit more effort in learning c++ then using c#...
Hope this helps...
Still slogging my way thru this...
I got hold of an MSDN disc, first off I installed visual studio 6 - bad move.
Had to uninstall before trying to install VS 2005, now I think it has screwed something up, every time I try and create a "Smart Device Win32" project, I get a "Project creation failed" error. I may have to re-GHOST my OS to get rid of it
So much time just finding out what apps I need and what options to choose to start a project...
I found http://channel9.msdn.com/wiki/default.aspx/MobileDeveloper.HomePage which seems helpful
Thanks for responses!
Evilc, you link of msdn is excellent point, many thanks!
I have also just started programming in C++ ..i dnt have any knowledge of any type of codes..i learned every thing frm MSDN libraries ( i have many many of them caz i have VS 2006 VS 2005 and VS 2008 )..i recommend you to work with C++ because it uses less system resources and is fast..hope this helps..check out my Kitchen coded in C++ ( link in signature )
Yeah, I think C++ is definately more what I am looking for from what I have learned thus far.
Re-Ghosted OS - totally fresh XP SP2, installed Visual Studio 2005, still the same error. GRRR!
Visual C++ --> Smart Device --> Win32 Smart Device Project == "Project Creation Failed"
Other Languages --> Visual C# --> Smart Device --> Windows CE 5.0 --> Device Application == Project created OK.
Some posts I have found on the net say it is an IE7 issue, I may try uninstalling that or flashing back to an OS image with IE6 only, but this is really winding me up and taking a *lot* of my time...
I uninstalled IE7 and the problem went away. Woohoo!!
starting programming windows mobile
hello
1. see my web site.
2. see my book recommendations, especially the 'programming windows ce' by douglas boling. It has an example for many things and a today sample too. Most is based on visual c++ 3.0/4.0. Embedded Visual C 4 can be loaded free of charge at ms.
regards
josef
Nice site, thanks.
The windows mobile 6 sdk actually has a today screen sample, along with samples of most of the things I need to do.

Are we using the same language?? Cos this (C++ Win32 for Mobile Devices) is by far and above the most difficult programming language to get into that I have ever tried. Yes, worse than ASM.
Trying to code an app that prints "Hello World" has taken me over 5 hours with no success yet - most languages I have a go at it's 5 minutes.
From http://msdn2.microsoft.com/en-us/library/ms901121.aspx :
Code:
int DrawText(
HDC hDC,
LPCTSTR lpString,
int nCount,
LPRECT lpRect,
UNIT uFormat
);
It gives a brief description of what the parameters are, but absolutely no examples and no explanation of what all the parameters do or how to initialize them, so even browsing an example is no use to me.
u can simply try
MessageBox::Show(" your message ");

Isn't that .NET ?
I thought the consensus was that Native Win32 or whatever it is called was the better way to go?
This is part of the problem. I cannot even work out what to put in a search engine to pull out info on the right "flavour" of C and for the pocketpc. It's *so* bewildering.
Hello evilc.
First I noticed you have some trouble with VS 2005. It probably won't be easy now, but if you ever get to format your machine again don't install it (unless you absolutely need some other features).
For C / C++ programming for WM device I strongly recommend eVC 4 as it is much lighter and responds quicker. (It's a free download as well)
Second, though you can program for WM in C# and VB .NET which are both .NET Object based languages and are probably much closer in form to PHP and Java then C, you can not write system components such as today plugins in those languages.
You need native code so C / C++ is the only way to go.
(Actually, there is a trick to combine C# and C++ DLLs to create a today plugin where C# will do the main stuff, but its pretty complicated)
What you need is to learn basic Win32 programming and using the windows API. They are almost identical for Windows Mobile and Desktop windows versions so any book on Win32 should teach you the basics.
(Personally I started with MS book on MFC and studio 6 but I would not recommend it)
Finally:
I would gladly explain the parameters of DrawText but I am not quite clear on how much familiarity you have with the Win32 mechanics, since the languages you are used to obscure them unlike C which gives you extra power but also makes you work much harder to get anything done.
Do you know how to handle messages, and how windows manages all abjects using handles? Any familiarity with GDI?
If not, it will be pretty difficult to explain.

I tracked down the problem when I got home and installed on my desktop. When doing it on the laptop, whilst installing SP1 for studio 2005, I had hit "Not Now" to a reboot request and it had said installation failed. When I installed SP1 on my desktop and said "Yes" to the reboot request, the problem went away, so I guess it was fixed in SP1 but the installer is a bit picky.

Wish I had that advice before as I wasted a day messing around with an MSDN CD, trying to work out what to install and what not. So does the eVC 4 download include an IDE? If not, what do you use?

No GDI Experience. I take it this would be the library of choice for drawing the screen of a today screen app? Stuff like the HTC Home clock or the new Face Contacts - they would likely use Native C++ and GDI? Doesnt strike me as something you would do with a form.
Also, anyone got the skinny on vertically scrolling by click-and-drag inside a today screen app? Just a case of enabling a parameter? Has to be coded manually? Best way to do it smoothly? If you have seen the Conduits Pocket Player 3.x browse list - how it "eases in" and "eases out" at the ends of the list, has inertia so you can "flick" down the list, the alphabetical bar instead of the regular scroll bar - is that all coded manually or is there an api or something that can help?
Thanks for the help!
I just noticed your apps in your sig - checked out LVM time - noticed there was source - wooohoo! I generally pick these things up by example.
All that code just for a (configurable) clock on one line - wow. Great though, a really good example of a today app - minimal enough in functions so it is easier to suss how it all slots together, but full featured enough (implimented example of an options screen - yay!) to show how to do various things.
And Gnu as well! Nice, this will be the basis of my first test project too I think - at least now I have a framework to test out what I want to do and how to go about it without having to work out how to code the basis of the application.
I thank you from the bottom of my heart sir.
I tried to build it in VS2005, but I got a
fatal error C1083: Cannot open include file: 'todaycmn.h': No such file or directory
A quick google search showed todaycmn.h was part of the SDK, I found the file, dropped it into the headers section of the project, but no joy. I will probs just try eVC.
Oh, and having developed a today plugin, maybe you can answer this one:
As far as I can tell so far, debugging isn't very easy with a today app - something to do with the fact that the dll is not releasable? Is this an issue I will come up against? I hope its not a case of "reinstalling" the app each time you want to test... I was thinking maybe along the lines of have it as a normal app for debugging, then make it a today plugin when you want to build to use it?
I dunno, probably trying to run before I can walk, my books shoulda been here today, oh well. Sorry for all the questions...
@evilc:
Are you using standard Win32 or MFC?
You may want to try using MFC since you get the flexibility of native development but with some nice class libraries that make your life easier.
As for click and drag behavior, that is usually implemented by handling the WM_LBUTTONDOWN, WM_LBUTTONUP and WM_MOUSEMOVE.
When you get wm_lbuttondown you set a flag that says the user is dragging. You use wm_mousemove to update the stylus position as long as this flag is set, then you unset it on wm_lbuttonup.
That's the basic idea anyway. Someone made a post about gesture recognition in this forum a few weeks ago with sample code. You should see if you can find that.
Managed Today Screen plugins
See:
http://msdn2.microsoft.com/en-us/library/ms839442.aspx
for some background on the concept.
And:
http://www.christec.co.nz/blog/archives/279
Outlines what I think is a very ingenius technique for managed today screen plugins.
For those of you that want an easy way to make a today screen app in c#. Chris did all the C++ work for you.
Also I forgot to mention that the SDK samples cover all most every application type you can think of. Most of the good ones are Win32 though.
Also, keep in mind that you can use P/Invoke from your C# apps to call native APIs. So don't let people tell you you need to use C++ just because you can access more api's. I will say that you should use C++ for games, or other apps that require high speed or advanced GUI's (it is VERY hard to do interesting gui techniques with C# and interop, trust me).
And finally, I would highly recommend using the most recent version of visual studio you can get (especially if you're using vista), unless your machine can't handle a newer version. I say so because visual studio gets more and more powerful as an editor with each new iteration and I personally can't go back after I get used to the new features they introduce. And the new versions are almost necessary if you're going to do .net development.

Porting a game from PC to ppc

Hi, I never did that, but I was playing to Anthelion 2 on my PPC and I thank that it could be great to port Homeworld 1 or Cataclysm to the PPC, and I would like to know how to do that, I think that I could "recompiler" it, but I don't know how, and I would like to know if a tutorial has been created somewhere on the net?...
I'm not sure if it would be even technically possible. Well, the newest pdas _might_ be powerful enough to run something like HW1 but i'm not sure if it's such a good idea. Did you try to run homeworld in 640x480 resolution? Most of the time you'll see ships as groups of two to eight pixels. Now imagine it all squished on a phone three-inch screen: try ordering your corvettes to smash that annoying bomber on a screen that small I think that a bit better idea would be porting really old games, that were designed to run in VGA or even lower resolutions (SubCulture, Command&Conquer, I-War, Dark Forces are some of the titles i'd pay for ).
Anyway, back to porting subject.
First of all you would need the source code of the program you want to port - in case of homewrld1 it's not a problem.
Secondly, you would have to make sure that all libraries (graphic, sound, input, etc) used by a game have windows mobile/windowsCE versions. Again, homeworld1 seems lucky since it has been ported to SDL - a multiplatform opensource graphic/sound/input library.
But that's where good news end. Porting a game is not just a matter of grabbing the PC version source and recompiling it. If it was as easy, we would have hundreds of PC games already ported You need considerable programming skills to actually create a port because usualy not all libraries used by a game a compatible with WindowsCE. An example - the opensource version of homeworld uses OpenGL for graphic rendering. The pocket version would have to use OpenGL's "little brother" - OpenGLES. As far as i know, they're not 100% identical, so to put it simply, you would have to make the game talk in OGLES language, instead of standard OGL. And doing changes in graphic rendering routines usually breaks something else, so you'd have to go and fix it.
I'm not trying to discourage you here but i'd suggest learning to program for WindowsCE (or at least for PC) _before_ attempting to port anything - doing it the other way around will be just a waste of time and a source of frustration.
There are some development resources that can help start the adventure with programming here on xda. You could also search for some general C/C++ tutorials targeting PC's. If you consider getting into programming, i suggest checking out SDL - Many games use it, and thanks to this library you can skip the OS-specific part of coding and get right to the fun stuff - a program that actually does/displays anything For an even easier start, you might want to check out QuickCG - a SDL wrapper simplifying the coding even further.
Oki, thanks for your answer, I've a friend who is learning to program in C++, so, I'll ask him if he can help me to do that, it would be great to have this game on a PPC (perhaps the Diamond, because it has D3D and OpenGL Drivers, or of the iPhone, but I guess that the programming language is not the same as the PPC...
[EDIT] STARCRAFT would be great to, and easier to port on PPC, because of his age and that he uses 2d Graphisms...
You should look into the stratagus engine.

Nice Engine, but it's not Starcraft, but I can't find the Source Code on the net, they could give the source code with the game when you buy it

noob question: How to start programming?

Hi all,
Finally I've my HD2 and I must say, I'm very happy with it!
I'm no noob in informatics, I program in VB and VBA and I'm DBA in Oracle and SQL Server. But to be honest, I don't now how to start.
I tried searching the forum here, but couldn't find a thread: how to start programming on a WMO-device.
Thanks already for the info!
Koen
PS for example I would like to program this:
keyboard layout French (AZERTY)
T9 language Dutch

You start programming for WM the same way you do it for Win32. Just download mobile SDK from Microsoft and you're good to go. You use the same IDE, Visual Studio, for mobile programming, and coding experience is the same, in addition to the fact that a lot of code using WinAPI will just work. There are differences of course with regard to memory management or power management etc., but those are either documented on msdn or are discussed at length everywhere on the web.
VB and .Net won't be good for your purpose though, you'd need native C++ code for things like rewriting a T9 engine I think.
Hey hey!

There are much more. Please look for the "stiky" posts. There are often very usefull informations. Sure, the moderators open some stikys "just-for-fun"... ... but many topics are realy interesting.
Some external sites can help you, too:

and
http://www.smartphonedn.com/
you can became a part of the msdn (winmo special) here:
http://msdn.microsoft.com/en-us/windowsmobile/default.aspx
When you became a good dev. You should look for 3rd party stuff like:
http://www.resco.net/developer/default.aspx
For the beginning it should be enough.

You can also program in mobile java, which will make your app portable to more devices.

Do you want to be a ROM chef, or programmer?
Or both ?
To just program for the Windows Mobile OS, you can
grab a (free) version of Microsoft Visual Studio 2010/2008
and download the WIndows Mobile development resource kit
from them.
Then you can blast away in C#, C or .NET
If you just want to cook ROM's then look at the kitchen thread.
Look at that thread anyway
Try Visual Studio, VB.NET and the Windows Mobile SDK there it is s
Hi mates, want to ask which is the best programming language for WM? C, C++, C#, VB.Net or something else. I did use C# a lot and can do little thing with SQL Compact. But, it seems lot of the current applications are not require .Net Framework installed on WM. Are they using C++?
Also, is there anything need to be considered for WM Web Programming (such as JavaScript, CSS support)?

yep. most WM apps use C++, but even the C# apps will run as most of the ROMs contain the .NET fw by default

Microsoft has an SDK for 6.5's gesture support. I've not got around to using it yet though, so can't comment on it's quality or breadth of support.
Is there something I cant build using C only in this phones?
I mean can I build a complete rom, applications and such using only C?
thats the only lang I know so...

I've seen that, what about buttons, sliders, tabs, flickable lists and all this stuff though. I've never developed for a mobile platform and I'd imagine starting from scratch with all UI elements steepens the learning curve quite a bit.

There are pros and cons to using managed code (C#/VB), and the same holds true about native code (C++). The former is much easier for high-level tasks, but you get less control and it may get a bit tricky when you need to access WinAPI not included in .Net CF (although there are usually ways to do it via Platform Invoke). .Net applications start slower, which may be an issue for certain tasks. Native code is (should be) faster, but a bit more complex and you don't have things like automatic garbage collection and so on. Sometimes you need a couple of lines of code in C# instead of two dozen in C++. Sometimes not. On the other hand, writing something like a graphics-heavy game in C# would be a strange endeavor. Some things are outright impossible like writing a system service, AFAIK. All in all, the pros and cons are described at length everywhere, and it's up to you to decide.

In the Development and Hacking section you'll find a C# GUI framework (it's called Manila UI Framework or something like that) made by a fellow XDAer.

If you want non-standard UI elements it can get tricky. For standard UI it's a no-brainer. There are some third-party libraries available. In addition to the C# framework I mentioned earlier, there's Qt (a cross-platform UI framework used by Opera for all their desktop (Linux, Win and Mac) and mobile (WM and Symbian) and embedded platforms including TV set-top boxes) incarnations, Airplay SDK that's a cross-platform framework for Android, WM and iPhone, some others I can't recall right away. They may or may not be free however.
Thanks for the reply, good to know about Qt. I'm vaguely familiar with that, had now idea it found it's way to Windows Mobile.
The Manila framework is called Manila Interface SDK, at least that's the only match I found.

Actually it is not the UI but the SDK that has a steep learning curve. Besides the usual loops and if then else.. you need to know exactly which library does what and there is the confusion as there are a couple of them doing similiar things eg Messaging API. At least that is what I encountered when I first started and I agree that C++ has a huge advantage over C# or VB.net as it can interact directly with the hardware api instead going over in a big circle and sometimes, some functions can't even be achieved using vb.net!
Just install vs.net and catch up on OO by diving into vb.net.
You'll be fine coding in either C# or VB.NET, the BCL for Ce is leaner than that for full blown windows but still very usable. After installing vs2008 don't forget to update the default install to wm6.5 sdk.

Hi mate,
I reckon c++ so u dont need to redisttibute the framework and your app will run fast, but if u want to write apps with db access net framework is the easy way, I'm in Sydney and I do c++ so PM if u need some help,

What language and software uses android for programming?

Hey guys im considering porting/recoding an app from VB.net to work on android, but i havent got a clue what language is used in android, could someone tell me its name or some sort of website with this information?
Finally if someone is experienced in programming apps for android, i would like to chat about a few capabilities of the language.
Thanks in advance!
Android is Java-ish based.
i would recommend you checking out the program Eclipse.
The main applayer is java based with some xml thrown in. But there is a native development kit that you can compile c c++ and many other languages to run on an android phone. But since java is virtual machine based an app written in java will run on all phones*(some caveats like os version) while the app in ndk will work on only hardware that it was designed for
Also, is Google not working? A simple search for "Android programming language" would answer this question
From something awesome

hmmm, yes there is google but not what im exactly asking, and that makes me ask this:
You talk about c & c++ and other languages compilations to run on android phone, is vb.net a part of that list?
Could you show me a website or something that says more about that dev kit? im basically trying to port my apps from vb 2010 express (windows forms based) to android and if that thing is not possible should i use java to code it all over again?
Thanks in advance!
http://developer.android.com/sdk/ndk/ this is for the ndk but it is not as simple as just compiling your code with the ndk. You will need to rewrite some of it to actuallytie into the android apis
You should really just use the java sdk. You will reach more people and be able to find more help and info
And I stand corrected, while there are projects trying to bring other languages to the ndk it is at this point just C and C++

oh well in that case i will need to learn java.... thanks mate, i think its easier to just rewrite the whole thing really i like proper optimizations and ports most of the times lack them.
Thanks for the information thats all i needed.
PS: rep added
if you know vb.net well you'll have no real problem with java.. it just adds brackets and semicolons essentially lol. I learned java in college and then was thrown into the .net framework using c# and i love the .net framework.. its so hard for me to go from using Visual Studios to Eclipse to make an android application because Visual Studios (which im assuming you use, is so powerful).. But yes android is java code behind and html (preferred) GUI. You can make your GUI using java but trust me its terrible!

You can use Javascript+HTML5 (it's complicated to express here but the whole things is pretty much native).
Python aswell, use SL4x or Kivy (Kivy is pretty good but it's still too new).
Sorry, being hate Java too much.

No you dont need javascript or html5.
Android has a ui layout system based in xml. Its just there to arrange objects that you can access from the java code. So a little xml and java is all you need

The right way to do GUI is with Java, with the official SDK from Google.
Some non-standard way to do this is with Javascript (just a GUI wrapper from Javascript to Java) and Python (again wrapper to Python).
You can choose which way you want, many people I know didn't like Java, and they choose to use a web application, and then they want to embed this to a native Android application, so they go with Titanium Mobile or some others framework like that. It's not as good as Java, but it's some other way to start with your application (Web app first and then Native app)

well ive been learning vb and i will admit that im still on intermediate level, even though i know all the basic stuff such as messing with its own functions, etc i still havent used any of the apis for it, the main problem with programming is that if u learn a language you would waste your time learning that one or else if u go learn to many languages you will end up not knowing none of them at all.
Ill see if i can mess with java, some people say syntax is a bit similar to c & c++
EDIT: btw, im not saying i dont find java good, a programming language that will basically run on any machine independently of the OS makes the language itself possibly the best and most versatile around.
I'm learning Android and I use Java and XML. I'm still a beginner though.
