What programming language do Android developers use??

A) What programming language do Android developers use??
B) and what language are most apps written on?

B) Java
http://developer.android.com/guide/topics/fundamentals.html Everything to get started is there.

Android programming is done in linux, apps are written in java.

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.

[CLOSED THREAD] HoneyComb sdk preview avialable

Just saying
http://www.androidcentral.com/android-30-sdk-preview-2d-3d-graphics-and-dual-core-support-honeycomb

First of all, WOOT!
Secondly, does anyone have any success stories of trying out the Honeycomb SDK on the G Tab?

I love how they're calling sub views fragments.

+1. im downloading it now to try it on the emulator but id rather see it on my gtab
EDIT: Did i miss understand the reading? Because I don't see the honeycomb sdk "preview" in the android sdk/avd manager
EDIT2: nevermind it's there

What is the link for the Honeycomb sdk?

The Sdk can be found at http://developer.android.com/sdk/index.html... follow instructions to install... once you are up and running (1)install the honeycomb packages (at bottom) (2)run a virtual machine with honeycomb as the target (3) rotate head sideways... when creating the AVD I install all hardware and beef up the vm heap size, hw.ram, and sd card and its still really slow... sorry for rick rolling but it really was on clockworkmods twitter

Helloooo World!
I did a HelloWorld application and ran it in the emulator and it worked (slowly )! I am so ready for a gtab rom that will run these apks.

My first experience with Android was running it on the HTC Touch as a fully functioning emulator running from the SD card. Any chance of doing something like that with this?

If you want to rotate the emulator "ctrl f12".

Xoom might be released end of February, so who knows maybe we can get it (Honeycomb) soon. I love this forum and the people driving it.

They usually cut the release at the same time as a device that's launching with it.
(Droid/N1/NS)

I downloaded it and had a play around. It looks really cool, but really, really slow. I know it's because it is prerelease and emulated, but I wonder just how resource hungry it is on an actual tablet? I've seen the clips of the motorola xoom running it, but that is just a tech demo video it runs, not the actual thing, so I am curious about this.
Anyway, looks really good and seem quite intuitive.

Has anyone tried to pull any of the APK's out and see if any of it works with one of our ROM's
I suspect kernel and framework issues would make this unlikely. I might try here shortly, but it's not really something I have a lot of experience with.

The reason that it is slow is not because it's resource hungry, it's because the emulation of ARM devices sucks balls.

The reason it's slow is because it is pre-release. First they implement functions then comes the performance tuning.

Have you loaded a vm with a cut release? Slow as balls.

Exactly, the emulator is slow no matter it being pre-release or release. My quadcore system with lots of ram runs it the same as my dual core low ram system. Heck the virtual Ubuntu box I sometimes run on my bigger system runs it the same.

[Q] Xoom Honeycomb Port

So, seeing as we all want us some Honeycomb, what would it take to get the Honeycomb on Xoom ported to Adam?
Sent from my ERIS GSBv2.1 using XDA App

Honeycomb source AND some packages from NVIDIA for the harmony dev board supporting HC.
We will also be able to port it over from the Malata tablets once they get it.

So I'm guessing that we just don't have a developer with enough skills to get us any Honeycomb love. The Nook is running the SDK and we don't even appear to have anyone trying. Running the SDK at the least would be better than nothing.

get to it then
Sounds like you have your work cut out for you. I can promise if it was currently possible we have ppl on it.

The issue is the way the SDK emulates the processor among other things. Its not possible and many skilled devs have tried plus having a $1100…+ bounty.

Why do people not use the search functions, or services like google(we all have a google android device right)? Look no HC till we get the source code or can straight copy from device "A" with HC that is the same thing as device "B" without hc. SDK is the preview, it has no graphic acceleration and is ment for computer based emulation or single core emulation, like which is found in the nook color. People leave HC alone, if a DEV makes it, thank them with all your heart, dont stress them with trying to appease the mass. More than likely you should start spamming the forum with request for icecream because honeycomb may never be available to us because of googles decisions with the source.

Can a dev put a simular post like this

I still fail to see why we NEED to have source. With the similarities between the Xoom and the Adam (same processor etc) what else do we need to make a port? Why is the source so important?

Source is important to get everything working correctly. However, porting is possible if someone has the knowledge on how to do it. The devs that have these devices are darn good at what they do but we are hurting in this particular area. Not much to be done about it though.

Thats what I figured. I would work on it if I had any idea of what to do. I just do some app developing though so I have no skills. Thing is the emulator doesn't work well enough for me to test out my app. Thats why I'm asking what it takes to get this thing ported. I need it running like yesterday.

What issues are you having with the emulator?
If you can't get that working take your app in to a store that sells the XOOM (Verizon, Staples, BestBuy, etc), load it up on there to test and then delete it when your done. Not the most elegant solution but it will work in a pinch.

Haha. Very true. The problem is as of last night the project file is 829 MB. Thats why it won't run on the emulator. I don't know how to get it to accept however large that APK file will be once compiled. Other then the emulator just being slow thats my main problem. I can live with the slowness though. Just need to give it a ton more memory. Haha.
O. And the file is only going to get larger if things go as planned. Haha

IPA to APK

can someone of the developers make a converter.
IPA to APK converter, something like the PSXperia tool.

Doesn't work, ipa is iPhone and apk is Android

Posts like this remind me of when Super Nintendo came out and all these parents were freaking out on the evening news that their kids would want it and it wasn't fair... and that they should make an "adapter" so that the old NES system could play the new games. LOL

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

Which program should I use?

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.
