Hello all,
This post is in regard to the Google Android Challenge put out by Google to create/develop new software for the Google Android shell. If you haven't had a chance to read about it, it's basically a new OS created by Google to run on any type of PDAesque cellular phone. The challenge issued is then to develop new software for this OS (written in Java) so that when it is released it will have software available for it.
My question to all of you is what software would you like to see developed for this new OS? The reason I am asking for ideas is because I am a CS undergraduate student working in a research group to create one of these programs. Ergo, I figured asking you guys what you'd like to see created would be the best way to get ideas that will make sense and benefit the community.
Any ideas you submit here may be used in the creation of new software--if you require idea copyrights that can be worked out.
Thank you all in advance,
Jake

Hello Jake,
We'll I'm a Java programmer too, not thinking of entering the challenge though. Had a quick look at the SDK for Android and it does'nt seem like pure java, more like a hybrid of C and Java does'nt it?
Since I have'nt had a thorough look at it, I'd like to ask you a few questions regarding the freedom to program on the platform.
Since it does'nt use the "normal" JVM but googles Davlik where theres no byte code but script code, does it allow better interaction with the hardware, and is it faster? Also can you implement equallizers and other effects in a media based application, which of course was not possible on J2ME. I was thinking on a All-round mediaplayer for Android, something like Rockbox which maybe found at www.rockbox.org which is a linux based program used on iPods etc.. but has been ported to Linux based EZX phones.

Hey Folks,
I was wondering if anyone knew if it was possible to use Jython instead of plane Java for android development? I don't know much about Java development but I'm with Python. I was figuring that this might ease me into it better. Any thoughts?
Thanks,

Have you had a look at the Android scripting environment?

Thanks aksd,
I don't know how I didn't find that before. Perhaps I should have just searched for Python and Android as opposed to just Jython and androind.
Anyway, this is very cool for prototyping and simple scripting. However, the main thing I was hoping for was writing apps in Python (via Jython) that could then be distributed on the Marketplace. It's kind of to bad. It doesn't look like anyone is really trying to port Jython to Android because ASE is sort of Google's official response to the whole thing. On the whole, a really great thing for people who just want to script Android but not really for App development.
In all of this searching I did find some interesting information about how to link in C libs so you could code some of the hardcore speed sucking elements in C (like a game engine) and then make calls into it via Java. I didn't know that was even possible so... Pretty cool stuff.
Hey ngrava,
I'm not much into scripts, so dont really follow whats happening with scripting and Android.
If you wanted a bit of a performance gain you can use the NDK and call the JNI to execute native libraries or code. been there for awhile but few use them. Java is just so much easier than C .
Theres a lot of interesting stuff going on on the Android platform, Mono being ported to Android, Scala being ported to Android, I'm actually currently working on profiling the performance of scala code on android.

On the Google DevFest on Argentina, Google´s ingeneers afirmed that they are working to make more languages availeable on Gingerbread, they specifically mentioned Ruby. We just have to wait to see if this is true and if we are going to be able to ship apps of other languages to the market, and I´m not sure if they will be backwards compatible with earlier versions of android as well.

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.

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:

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
I have a question as well, are there any free-for-freeware frameworks for touch-friendly applications? Is there a Sense SDK?

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,
cheers,

BTW is there some good app for programming in my HD2? taking my work on the go? something like visual studio mobile version?
So I have an application ready, but its written all in JAVA. I have the avd and sdk and eclipse all configured, but how would I change stuff like mouseListener into "touchListener". If you guys dont know what im talking about PM me xD?

I dont have the answer you want, but you could always use the android java app. You can find it on google, it works with some java apps, cant guarantee it will support yours.
Unfortunately I do not think it is possible to turn a Java-based applications into Android without rewriting it. Even though the programming language is the same, the UI components of Android are different that standard Java.
It for sure is not possible to port it to Android without rewriting parts of it.
All UI stuff definitely needs to be adapted and/or rewritten. Also dependent on your application you have might have to optimize parts of it to work well with Android due to lower hardware specifications and so on.
Ahh well thats unfortunate. I was hoping for some kind of program that woudl do this for me.

Do I need to learn Java to program in Android Studio? Or I can just jump straight into it? If I must learn it, can u guys show me a great way of learning Java? (I have a Pascal basic BTW).
You definitely must. Java is the main language for android development and without knowing it you can't do anything advanced.
To start learning you can use docs.oracle.com/javase/tutorial/. But learning is nothing without practice so start your own project and use Java in it. It's relatively easy language so you can start quickly.

You are welcome. To be honest I don't know any video tutorial and personally I think the best way to learn programming is practice. So just use any Vogella's tutors and code your apps but always try to make them more complex.
Java is important for Android studio
Yes, you need to learn Java properly before visiting android studio.
Because Java is key to do programming in android studio for Android developers.

I learned from a YouTube series called "mybringback" 5 years ago. It's still a good place to start. Also, a great website that interactively teaches you to code is Codecademy.com. They are mainly a web-development website, but recently added java to their courses. It may be worth trying as well.
Root it and boot it!

I have collected many good tutorials for Java and Android here.
Hope it helps
It best to learn Java, but today you can also use Xamarin to develop cross platform apps using .net (Visual Studio 2015).
java is main language to android studio
if you are using android studio, Java is a must. But you don't have to learn core java, you can just jump in to android programming, coz there are lots of different library there.
i would suggest using android studio instead of others, beside they are free, they are directly from google
Yes, java is must in order to develop android apps. Android virtual machine runs java codes. So android apps needs to be in java.
Now a days, there are so many frameworks and tools available which allow you to develop android apps in other languages and convert the apps developed in other languages to java code to deploy and run on android.
I think it is a good idea to directly code in java as you can easily understand concepts involved in android os and develop apps that perform well proving best user experience.. It is not difficult to learn java and android framework to develop android apps.
As others have pointed out, yes you must. However, if you have Pascal/Delphi background, that helps a lot! So loops/ifs/functions are no stranger to you. You "only" need to learn about classes, interfaces and such stuff, not very hard.
Luckily for you, there's literally thousands of Java tutorials, books, videos, anything you can think of. I always like to stick with books from respected authors and/or the language authors. So for Java, I'd go with https://docs.oracle.com/javase/tutorial/java/nutsandbolts/index.html (just an example, there's tens of other valuable books/tutorials).
