i want to start making apps for android but dont know where to stat i have the sdk on my desktop but thats about it. If someone could please help me or push me in the next step please do so.
Just go to the dev guide on the Android website to start making your first Hello World app. As for language, Android (I could be wrong) uses Java. Again, I could be wrong.

Indeed, Android uses Java. I'd suggest learning it before attempting to program for Android or else you'll feel like it's gonna be too difficult. There's plenty of books on Java, and some powerful Google searching will lead you to step-by-step guides to learning Java.
Also, go through the Android Dev Center for a lot of information. There's plenty of guides there on things like 'how to design your app to flow with the overall android feel' and 'designing icons to fit general android homescreen look'.
You're gonna want to download Eclipse for Java Programming. It's a free Java development environment much like Dreamweaver and Visual Studio are for web development.
Oh, and PLAN! Like any good development project, your project will not get anywhere if you don't know where to start and when to end it.
Plan first. Then plan the planned elements. Java is object-based programming, and just like building a house each object needs to be solid or else it'll crumble to pieces.
Same here. Thx for the advice.

Actually, you're doing things the hard HARD ...HARD way....
if you want to develop apps for android, Titanium Mobile (appcelerator.com) is the best way to go. It takes far less time to learn JavaScript , CSS and HTML then it does to learn pure JAVA, and then learn to implement Android's API.
There are a few things that Titanium Mobile can't do, but they are always working on it to make it better. And of course - it's free
I've made a few apps using it. Including an HTML eBook reader, Chinese Flashcard App, and a Simple Chat Client.
Their JavaScript API takes a bit to get used to, but after that, you can easily spit out a simple app in about a day or so.
I have a web-app Template that lets me dump a Web-app (html/css/js) into a project, and spits out a nice new shiny Android app ready for the market.... I also wrote code that lets you access the Menu Button on android too. So it's not like using PhoneGap where it's just a Browser session with an icon on your phone.
PM me if you're interested, and i'll show you everything i learned about Titanium Mobile so far (i'm still learning actually). Or if you want an app done, i can do it for you... free if it's easy enough

Wow, I'm very interested. I might check it out.

If you know the C or C++ language you could try out MoSync, depends what you like, some programmers like the level of control and speed you get from C++. If your content with simpler apps then maybe phonegap or appcellerator for you.
I guess that when mobile apps get more sophisticated javascript programs will be just as complex as C++ programs.
Thats my view, but then I like C++ better.

It really depends on how much control and you really need. If you're going to write games, then you do need speed that C++ and the Native Application Development API on android can give you. If you're writing a social networking app, the speed of C++ would really be an overkill.
As far as i've read, PhoneGap still has a lot of issues. And the build process is a bit more complicated than on Titanium Mobile.
If you're just using the regular Android API to write apps, i don't notice a lot of difference in speed execution between writing it in pure Java, or using Titanium mobile (using native code and UI elements - i don't mean putting everything into a WebView).
The current app that i'm writing now i don't think can be written using Titanium Mobile or PhoneGap (unless i added some native functions and did my own fork of PhoneGap).
More or less, i'm writing an App for Android and JRE/Linux systems that will allow me to enumerate, and access USB status bits, and USB data frames of a given USB device, and then allowing that USB device to be accessed through a TCP or UDP connection.
I might be able to do this with Titanium Mobile, but i don't think i can. As the only files you're allowed to access are on the SD card, application data directory, and temp directory.... i think there's one other place you're allowed to access too, but i never used it. However later today i might just try to see if i can access the /Dev/DSP01 (aka sound card) on an android device. If i can, i think i could write it using titanium mobile. I'm already halfway done with this app in pure java, so i wouldn't actually rewrite it in Titanium Mobile now.

Thanx mate!
If you looking a book or something to teach you the basics Beginning Java Programming for Dummies and Android Application Development in 24 Hours are good reads.
I'd rather not fill the forum with more threads so I'm just going to ask my question here. What is the best way to read the android dev guide on the device itself? Just going to the site directly? Ideally I'd like a pdf or something designed to be read on a small screen. The site can have formatting issues when read on a small screen.

I've been developing for a long time (nearly 30 years), and whenever I need to learn a new language I start with the Sams range, "Teach yourself whatever language in X days/hours". They're pretty good and this is available for Kindle, which is great if you use the Amazon Kindle app...
http://www.amazon.co.uk/Teach-Yours...1_fkmr2_2?ie=UTF8&qid=1287485537&sr=8-2-fkmr2
It obviously costs, but I really do rate those books as brilliant starting points. The rest is google and friends on here.
Hope this helps - good luck mate.
Personally, I've been coding in Java for what... four years now? I'm feeling dwarfed here by johncmolyneux but honestly, the best way to learn is to not use an IDE like Eclipse, but to use something that you have to hand-code everything yourself, such as Geany! You learn fairly quickly after writing a few applications.
If you are thinking "titanium", "mosync" or "phone gap" it is worth doing a bit of background research. There are several extremely powerful tools out there that can help you build cross platform apps - these are among the top ones.
bit more discussion about this here: http://forum.xda-developers.com/showthread.php?p=16703287#post16703287
There are a few useful reports comparing them - check out ours by googling "triballabs cross platform"
The Google App Inventor makes it pretty easy to create your own Android apps. Best part is you don't need to learn any programming languages. You won't be creating anything too complicated like a video game for example, but it's a good start nonetheless.
http://appinventor.googlelabs.com/about/
If you want to learn the basics of Java, then please check out a book called as "Head First Java". They really explain the basics with the help of real life examples to make things much simpler so that people understand.
Beginner app projects
I'm also just getting started with app development. Something I've been looking for is a beginner app project. Wish I could find a walkthrough of a simple app like a game of Hangman or something like that. I've been through the android developer training web site and got some good info but some things I'm still a little stuck on. Id Love to see an actual app (rather than just a mock up of some fields and buttons) and then a slightly dumbed down explanation of the code. Might be a lot to ask but man it would be great!
Hi everyone!
I'm pretty much begginer in Android development. I created some basic apps but nothing special.
I wonder what does it take to create a game like Doodle Jump?
It looks like not hard to do game, but I still don't know how to create anything that this game have.
Would someone who is professional in Android development like to explain it a little, and give me guidance to what areas I should learn more?
For example, how to create Doodle, dynamic background and how Doodle can respond to objects on it's way? And is all this created in OpenGL?

Game development is done by using extra frameworks which are probably paid versions. There are many softwares and tools available for this purpose if I'm true. Anyways if you want to start as a beginner in Game development, you may head over to this Guide : http://forum.xda-developers.com/showthread.php?t=1753131
~Cheers.

Yes, It can be done using OpenGL (ANDEngine can help you here), but it also can be done using generic tools, like the SurfaceView (the doodle jump background is a repetitive image, relatively easily achievable using surfaceview).
The platforms can be created aleatorily at level start, and can be storaged in an array, or a List (much better, since the List are dynamic) to manage them. Remember: all the platforms are the same image, so you only need their relative positions.
An algorithm to interact with the platforms can be:
Code:
if (doodle is falling) and (his feet touch a platform) then
Jump!()
end
if (doodle is jumping) then
scenaryScroll()
applyPhysics()
end
PD. I'm not a professional, I'm only giving you some suggestions .
Thank you for your answers.
I have to start android programming for a project.
The project involves using the App to remote control a camera attached to the pc which is running the web-server.
The App does two things:
1) Send user-inputted parameters for the photo capture to a web-server.
This is relayed to the web-server (using gSOAP or other web-service).
The web-server then calls the program i create on the server, which captures an image from the camera.
The program also has other functionality like image manipulation, making a timelapse movie etc using these captured images.
The program sends back to the app a video file or image.
2) Receive a video file (either saved in Gallery, or viewed inside App).
As you can see bulk of my project will be not on the android but on the server.
My question then is, how do i approach android programming?
I want to make the best use of my time and not have to learn the A-Z of android programming. This is not me being lazy (I have done a few chapters of Sams teach Yourself Android & completed Google's online tutorial on android) but just wanting to spend, what little time i have, wisely.
So i suppose my question is:
1. What areas of android should i concentrate on for this app (e.g. web-services, drawing buttons etc).
2. Any resources that would help me in this quest (e.g. templates)
Apologies if it was long and drawn out, and thanks for reading so far
What are the requirements of android app development?
what all am i suppose to know? rit now i just know c++ is that sufficient?
any help will be appreciated
First I'm sorry for my English's mistakes,I'm brazilian.There are a long time ago that I already knew about xda site but I just joined in it now because I need a lot help into apk development.I develop games in Construct 2(paid) for Android but when I finish my game in the program I get a HTML version of it and sent to Adobe Phonegap because like this I can get a apk without the boring problems of make it in ConcoonJS.My problem is when it get back the apk because the apk comes just like a ''raw'' project.What I want to mean is that the apk by the way doesn't come with a icon/logo(I think that like this it must come without the name of the company for instance too-n other words just a apk with a log ''build app'' and the game).In Unity we can put icon,name of company,compatibity and another things but I prefer to make in Construct my game because Unity is more complex than.SO what I want is a program that can give these informations for my developeds apks.
Thanks A LOT to everybody that answers my question!
Instead of using PhoneGap, try to use Intel XDK and use Crosswalk as the wrapper for the game. Much less issues and you have better control over versions and plugins. Plus, it's free for unlimited apps, unlike phonegap.
Hi. Does anyone here know about making games either for Android or for Windows or for both? I was always such a gamer addict but eventually I stopped playing because I feel like i played so many games that they dont work for me anymore haha. So I was thinking of creating my own game as I have ton of ideas.
But Im quite inexperienced in game development. I know a bit of programming but not sure how to proceed further so I have an moving object in 3D space. Am also not sure which language to pick, people say Java is good because if you code game in java then it will run in every kind of device.

First of all game development is not hard but will take you long time and that's why it's considered hard. Every little feature you code will take you long time, then you will have to interconnect them and ensure it works correctly, then polish each of these gameplay features as well as do perfectly good visual assets.
Secondly, please don't use Java. LibGDX is the only game engine (actually its library, not an engine) for Java and it's nowhere as good as popular game engines are. Java games can be compiled once and technically be run on any platform like Linux, android and windows in same time (there are often errors though). Now while this may seem like an advancement and really great thing to have, it's actually not. Because any popular game engine will let you code your game once, and then just compile (a matter of clicking one button) a individual game package to each platform like Xbox, android, windows, browser and the like. So the only difference here is that you have to compile the game few times but you still code it once.
The game engine I would suggest you is to use Unity. Unity is very easy engine that is suited for every kind of game. One more thing Id recommend to you is to learn from free tutorial instead of paid one. One of websites that teaches you for free is this gamedev blog - actually I'm in game development for quite long time but it still taught me things i didn't know about. If you have troubles following the tutorial then you probably should learn some C#.
