Yeah, but the way he said it sounded wrong. The Android kernel is programmed in c,c++ and is a Linux based os. You can program apps for Android in most languages now: c++, c, and ruby just to name a few. Most choose java since google has pushed it enough and made it simple.

The app itself is written in java. And, there is some XML.
Check out eclipse.
Here is a help site for windows: but you can apply it to linux or macosx

This. Java is certainly the most widely-used and most supported by Google, but more and more compilers and VMs are emerging. For example, the MonoDroid project is working on a Mono VM for apps written in C#.
PHP is also on the rise

Linux isn't a language. The user is asking for programming languages.
Pretty sure you can also code apps in C using the NDK. Or maybe that's just OS code, can't remember. Either way it runs extraordinarily faster than Java obviously.
EDIT: Just read up on it and apparently you can only embed C in apps using the NDK in conjunction with the SDK
I think I am going to jump in. I am a software/web developer and I have the Android SDK, Eclipse, Visual Studio 2008 and a number of other tools on my dev box. I love coding in C# but I can do Java and some other stuff too. What is a good way to get my feet wet....aka "Hello World" ?

Thanks. I just got Eclipse (Helios) setup with the ADT pluging and I am messing around with the emulator. So this is basically what it used for testing/debugging etc. or is there something better?

That's pretty much it. You won't enjoy anything remotely on the level of what you're used to out of something like Visual Studio, but once you figure out Eclipse (and that can take awhile, it's probably one of the more inscrutable modern-style IDEs I've ever used, and I've been doing this for 30 years; and I'm sure I'll get flamed for that)... but once you see the world through Eclipse's eyes, it's about like writing any other app.
I've gotten into Android dev and back out again several times. Usually I get tired of Google's rather sub-par developer support and go back to some type of paying project.
But for some reason, there is a certain kick to seeing your app run on a phone the first few times.

Yeah you can either use the Virtual Android Device to test your app OR use your phone and you the ADT plugin will install the app onto your device. The emulator takes a long time to start up. Whenever I'm bored and want to write a app for fun, I tend to use my old device (G1) as a debugging device because I can't stand how long emulator takes to stat up.
Thanks guys. I have my first little app up and running in the VAD emulator.
I found out that you need Eclipse 3.5 (not 3.6) and the JRE 1.6 for everything to be happy. Now where to go from here....
This is turning into a nice little getting started thread. I hope people who have other suggestions for noob developers will continue to post.

Oh nothing to be sorry about, you show that you have a better grasp of the architecture of Android OS than 90% here by distinguishing between an OS and a Kernel.

Common misconception. There is no "linux" out side of the Linux kernel. The most basic form of OS that runs ontop of the Linux kernel is all of the GNU software. That you would call GNU/Linux OS if you wanted too.
Of course the major distributions kind of perpetuate the misconception... meh.

Hi
i need to run some JAVA APPLICATION on Acer Iconia A500, but i can't find JVM for my tablet.
Any ideas?
thank you
Sorry No Support for Java Virtual Machine yet so Java Applets will not run on the tablets for android. be nice if we can get java support for android sometime soon.
I read something the other day that I thought was pretty interesting...RIM and Google claim that they have the full web with Flash, but if you think about it, Java is all over the web and without Java support, that's not the full web at all.

I'm aware of that. All I'm saying is if you're a Toyota dealer and you don't have any Camry's on the lot, don't claim that you have every Toyota car in stock.
Technically, it does have full html not web. Java applets and support are an add-on. Android is coded different it was built for phones. This move to tablets is a big move not just adding a bigger screen and better video support. Java support will come once it is profitable for Android/Google.
rorytmeadows is right, certain things just don't work, but thats apple and oranges.
Windows can do somethings that others can't due to its popularity,
Linux can do things that can't be done by others due to superiority.
Mac can do nothing due to the lack of real users just people who like fruit.

Hello! Question about overclocking the tab 10.1v!
Is it possible to overclock the tab? It doesn't feel so smooth like the SGS2!
PS: And how it look with sms or whatsapp? Is it possible to include the "phone" function to the tab?
Fist try rooting and change the CPU profile from Interactive to Performance or onDemand - There is a massive response gain from this
What needs to be done to OC is make a Kernal with proper voltages and CPU Frequency to hand the demands. and not constantly bootloop

It's Linux you can do anything you dam well please if you go out and Learn UNIX, C, C++, C#, Java, Java again because you forgot that Var and var look exactly the same in a text editor, Realized you forgot everything about UNIX, C, C++, C# Re Learned them.
Then spend 4 Years trying to build apps and everything that you make doesn't seem to work as well as things other people program, so you go do research optimization research get bulked down with several thousand lines of code for 1 line which is being talked about.
Only to realize that the reason your apps aren't living up to your expectations is because you weren't wearing your lucky belt when you compiled it...
Or you could go out and buy this brilliant device called a phone if you are unsure of what they are here is a resource i found usefully http://tinyurl.com/3xpwmt7

Open up the kernal and see if you find all that is needed to drive these tabs (probably a good move to strip out what isn't needed as well)

First off post logs in the thread (i cant fix something blind).
I need to know the exact scenario and what was being done.
If you are looping follow my recovery method. it is failsafe (ive used it today alone like 4/5 times while testing).
Then reflash the kernel and post logs if you face issue.
Be aware, it is easy to boot loop this thing. It may not have been from the kernel.
Please get accustomed to the process.

Spoken by someone who has never written a program in his life.
The logistics of this requires human interaction. Android programs are written in a COMPLETELY different language than iOS programs. While both programming languages can produce the same results, and obviously use the same graphics data and stuff like that, a human programmer must make that conversion as how they get to that end result is completely different.
No developers are working on this. Its a waste of time.
Question: if I remember properly, Android uses a virtual machine, called Dalvik, to run Java code. Could Dalvik actually run Objective C (iOS language) code somehow?

programs that are coded in C run natively they dont run in a VM like android apps. Thats why its possible to use android apps on other platforms (providing they have the dalvik VM) like the blackberry playbook but you couldn't do that the other way around.

No its not just a Java VM and actually works quite differently than a normal Java VM. A regular Java VM works almost like an Emulator within the device running it. The Dalvik VM actually takes the program and uses its own class libraries, it converts some of the java files when its compiled into its own format. This saves space and memory usage, due to the programs obviously needing to be run on devices with limited memory.
The Android SDK also has an ungodly huge amount of libraries within it as well withe specific code design to do basically anything.
have an idea ask Google to try and create android to read IPA or other formats then android will be the best as developers will want to create games, apps and other things and make life easier for everyone as it will be like this in left hand iphone in right hand Samsung galaxy s2 really good android phone which will you pick me i would go for the Samsung as it's better as i have one but if it could run IPA. Iphone will probably unexistant just saying but it's best to ask google. for more easier methods to create games and apps just like ipa is really easy to create apps
Hello XDA Devs. I am pretty new to the concept of people like me creating apps. I am very inexperienced and I am trying to make a game for my android phone. I knew that Google had an Android SDK but I learned that Adobe's Flash Professional can create apps for Android as well. So which program should I use to create a game?

Uh, I wouldn't use the Adobe Flash thing. First of all, it should be slower and Adobe doesn't provide flash player support for Jelly Bean and later. So it runs on old phone only. (I know there are ways to get flash on newer versions. But they aren't optimal.)
So use the SDK. It offers much more functions.
You can use an engine like AndEngine though. I'd recommend that. However, you need to know Java and the Android part.
Although I agree with going down the Java route, as you will be able to do a LOT more with it, Adobe Air is a viable platform for a Flash developer. (It's not the same as the flash plugin for browsers.)

I've not used it for a long time, no. I know it's compatible with my HTC One, and that's running Android 4.2, so it's been kept up-to-date. I did think it was the way to go for a long time, purely because of the fact that it's cross-platform, but I have less faith in it now. If I want cross-platform then I use Phonegap.
I'm curious now. Going to install it and have a play around

As mentioned above you could used engines like AndEngine. But if you are new to java as well then I suggest learning java and move on to creating simple apps. You can use websites like thenewboston or other various tutorials all over the net. Make use of youtube and google... they will help you.
