Hello all,
I am new to the Android scene and I wanted to find out if there are any good tutorials on app/rom development, what are the programming languages used, etc... I know learning from scratch is probably a long and bumpy road, but it is something I am interested in. I have already rooted and flashed my phone, good times that was. Thank you all for your help.

What's your existing programming experience? You could do worse than check out the anddev forums. App development is principally in Java though you can write parts of apps in C or even assembler.
My existing programming consist of very very very basic python, and some web stuff like HTML and CSS, I would basically have to learn how to program the ones you have mentioned from scratch, I have books for most of those though. I will go check out those forums and see what I can dig up Thanks for the info.
I bookmarked that page thank you, I just got a hold of their Eclipse software and all of their beginner tutorials I can't wait to dive into this stuff.
Me too. I know C, but only have a passing acquaintance with Java & Linux; Android I know even less about, not having encountered it till getting my Hero in February. I'm working my way through Thinking in Java (Eckel) to be followed by Professional Android 2 Application Development (Meier).
Even if your grasp of Python is basic it's still a start - you don't have to struggle again with fundamental procedural programming concepts like conditional execution, program flow control & so forth. Plus Python is an OOP language, aiui (I don't know Python) so you have a head start there too
I've installed Java, Eclipse & Android's SDK on this Windows box, but I'm thinking of dual booting Ubuntu as some things just work better in Linux, especially if one wants to cross compile ROMs. Aiui Cygwin, which I already use, can be a little problematic & when one is likely to be asking for help at times, it's useful to be using a similar set up to most devs.
I have been thinking about dual booting again, I just havent had to time to partition my drive and install some sort of linux release, UBuntu is the one I am most familiar with, which isnt very, but its a start.
I am going through those video tutorials from anddev.org right now, it seems to be similar to Python in the way the coding is done, I am excited.
I have also downloaded the Eclipse program, but I have the pulsar version, it seems to be geared more towards mobile development and I have gotten the Android toolkit installed and I have had the Android SDK from when I rooted my Hero (Which is awesome, running the newest Damage Control) good times.
I think I may have a java book on PDF somewhere as well, I will have to go look.
Atm I can't make up my mind between dual boot & Virtual Box, or maybe both, to see if I can wean myself off m$
I have been thinking about the dual boot option a lot since you mentioned it, not sure what to do, I may wait till this quarters class is over so that if something goes missing. it Sony be a big deal

I have barely developed anything since the BASIC days on the C64 and Amiga, and now feel inspired to create some financial applications for the Australian market - such as superannuation projections.
How hard is it to develop? A few standard calculations like you would see on a spreadsheet would work, with some graphing.
Most financial applications I have found are pretty basic and don't account for inflation in rising wages and fees, etc.
I believe I could attract at least a dollar for a well developed application for superannuation alone.
I have installed the Android 2.2 SDK and have no idea where to start. I presume this is some sort of emulated Android device I can test my applications on.
Are there any tutorials on how to get started? What's the development language?
All I need to do is create a simple text interface to input a few parameters to run some complex financial calculations on the back end.
A really sophisticated application would pull live interest rates or other data and enter that in.
Start with this:
developer.android. com/resources/tutorials/ hello-world.html
(take away the spaces, I cant post links yet )
These are all great tutorials that will walk you through the basic processes and applications/layouts. The only issue you will have is when/if you decide to go through the "Tabs View" tutorial, there are a lot of errors in the code, and I have no idea why no one have changed it, but you can PM me for the correct version.
If you want some basics on Java, just do a google search, there are a lot of great tutorials out there for beginning Java. I recommend doing this first, just so you have a good understanding of Java(which is the development language), it will *REALLY* help out. You can incorporate other languages, but for the time being, stick with Java.
Yes, the SDK comes with an emulator so that you can test your programs without having to install them on a real device. In addition to what Jimmy said (and I can't stres highly enough that you should start with the Android Developer's website and tutorials), you can go to Stack Overflow which is a programming Q&A website. People there are generally very helpful, as long as you've shown you've actually put some effort into solving your problem before you posted your question.
Fair enough... So it's basically about learning to programme for Java? How hard would it be, realistically, for someone with no application development experience?
You need a basic grasp of objected oriented design & programming, along with an understanding of the Java language. When it comes to gui aspects & all communication with other apps/data on the device, you have Android, rather than the usual Java class libraries such as awt or swing.
How hard? It's doable, imo, but will depend on aptitude. Start with Java & then add in Android when you feel like more material to get your head around.
So basically getting started requires me to learn application development like on any other platform, in OO and Java. I may as well do a course or something then. Would a few weeks doing some sort of intro course help?
I'm sure an appropriate course could be very helpful. Though I'd steer clear of those short courses claiming to turn anyone into a valuable skilled programmer in only xx weeks, if only because the tutor will probably know less than you on the subject. Better one which makes credible claims regarding its introductory nature. A couple of degree level intro modules on OO or Java should be of help.
Hello everybody, long time lurker, first time poster. I'm posting to ask about where to get started in developing Android applications? I have half a degree in computer science, am familiar with coding, and work in Android software QA, but I'm trying to get my skillset up to the next level and actually start developing applications on Android. Is there any specific books or literature I should read to get me started on my journey? I'm also a long time IT guy on both Windows and Unix-based systems, so I'm by no means computer illiterate. I'm also a long time phone modder as I've been tweaking Android phones since the original G1 running 1.0. Thanks in advance!
Take a look at the Android Developer guide. It has samples and tutorials. If you google, there are also several free PDFs on the subject.
A good Java book will also help a lot. Just start to write a few trial apps and you will get there quickly!
The best place to learn for me, is android web page:
Here you have everything to start:
http://developer.android.com/guide/index.html
And to set up the environment for developing:
http://developer.android.com/sdk/index.html
If you want to learn from the scratch, the links I posted are your point. You can also take a look to the tutorials:
http://developer.android.com/intl/es...llo-world.html
You can also start with java, if you want.. I reccomend you take a look to this:
http://download.oracle.com/javase/tu...ava/index.html
http://download.oracle.com/javase/tutorial/
and start from Java SE 6 (http://download.oracle.com/javase/6/docs/)

I don't know what your college classes are like for CS, but you should have the basics of programming, why not start writing some Android apps?
Start with the basic "Hello World". Get used to working with main.xml and TextViews, EditViews, ListViews, Buttons and Listeners. Android is mostly JAVA, some Android-specific operations and your xml files.
Take some of your CS 101 type programs and try to write them on Android. The more programs you write, the more you learn.
Try to learn something new everyday and in no time at all you'll be impressed with how far you have come.

Yes this is really a good advice
Just start writting little programs and you will go up soon
You could use the sample code that comes with the sdk, and start with different things: First, layout, xml and the like. You could then start with some othe things, like services, broadcast receivers, content providers, to get the feel of them. And finally, work with the hardware: Internet (wifi or 3g), bluetooth..

At Barnes and Noble there is a book called Android App Development in 24 Hours. It is a freaking great book. Helped me a lot when I started. It breaks down the chapters in to hours with exercises and explanations. Being familiar with Java fundamentals would be good, but not necessary. The first couple hours(chapters) explains the a general overview of the history of the OS and helps you build your first app. My favorite part of the book is how it teaches you to build and app piece by piece over the rest of the chapters adding new features each hour. So, by the end you have and app with quite a bit of features that work and you actually understand how and why. At the end, you have an app that has a lot of Android features as well as knowledge of how they work and can be used. It doesn't go into the more advanced features, but it is well worth the money for beginners. I still use it as a reference because of the easy to understand instructions. Sometimes, the Internet guides assume you have been using Java for 10 years and skip how and why they are doing something. And even then I doubt every veteran Java programmer remembers everything. I am half asleep so forgive any grammar errors.

Really good tutorial for the first basic steps. In terms of installing eclipse/java and hello world. He continues with his tutorial in part 2, part 3 and so on.
Android/fruItphone app. idea needs help...
If there is anyone who has knowledge on building apps for Android, I would be extremely interested to share with them an idea for an app. I'd hope this app would be able to work on that other fruIt based dumbphone, too.
Well, there is planty of developers out here I'm one of them (thought not the smartest ) so, if you want to share the knowledge, feel free to PM me
When starting with Android development most people start so by using Eclipse, so did I. Unfortunately for me this was a quite frustrating experience no matter if I developed on Windows or Linux. I often had troubles launching projects after some changes and was forced to rebuild the whole workspace (which takes a while esp. if you included a couple library projects). So after a while I decided to switch to IDEA which is a lot more satisfying. I never had any issues with broken projects and everything just builds so much faster.
One big difference (and it seems many people have troubles with it) is IDEA's handling of library projects. Unfortunately I think this is done in a very logical way, as each "project" is handled as a model. Means you create a project ("My app"), add a module for your main app project, and add new modules for each library project you would add. For each modules you can set the dependencies and say on which modules it depends.
In the newest version (12) Jetbrains also added an Android UI designer, which was one of the features not available before.
If you are curious you can download and install IDEA from their website, or when you are using Ubuntu you can simply download it from Software center.
http://www.jetbrains.com/idea/
And here's a nice article given a quick introduction:

IDEA rocks, +1. It makes my little Arch box work like a real PC at times
i use idea too,just feel good

What about the on-the-fly analysis performed by IDEA during development? Does it detect many bugs?
Have you never used this functionality?
Nobody uses this feature of IDEA?
I've only had a brief play with it so far - updated the Android SDK and loaded 1 project from GitHub, but it compiles like lightning compared to Eclipse. Thanks for letting us know about this - it's much appreciated
So how does it handle multi-module projects? The advantage of Eclipse/Qt Creator is you can keep multiple projects open at once plus the plugin integration with Maven and Git.
I briefly tried out IntelliJ a couple months back and immediately stepped away when it failed multi-module requirement for me.
More speed than molasses Eclipse would be nice, though the Windows version runs tolerably on fast i5 and SSD.
If it supports .webp on the UI designer (unlike Eclipse), then I'll be all over it!
IntelliJ IDEA has no workspace concept like Eclipse, but its project can have multiple modules: http://www.jetbrains.com/idea/documentation/migration_faq.html .
I'm a total noob/beginner when it comes to programming - never really been into it. That said, I've recently been giving it a go using Eclipse - creating my own Android app. I've just installed IDEA and find it far better to use then Eclipse. Really loving it actually.
I never got into Eclipse. The only Eclipse project I tried using was IBM's Lotus version of OpenOffice. The thing was huge, bloated with Eclipse libraries.
Netbeans is my preferred IDE (also good for C++ and others) but it, unfortunately, falls short for Android.
Intellij worked first try. Glad to see a forum for this on XDA!
Really happy this gets some attention, I've switched from Eclipse to IDEA a while ago and I can't go back.
IDEA is just so smart and works so nice!
I think the best part of IntelliJ is that when you are programming you do it in one environment, from IntelliJ I can see Jira stories, commit svn/git and everything else I do while programming, without switching to 5 different applications
I hope more and more people will switch to IntelliJ, thanks for this thread!
Isn't anyone here bothered by the slow compile times compared to Eclipse? I'm working on a relatively large project, and each time anything is modified it seems to rebuild from scratch. Eclipse in comparision is able to launch the app with the new changes almost instantly.
I love IntelliJ when it comes to it's editor and project management, but in the end it takes about 20s to get my changes on the screen. I'm probably saving some time not having to bother with corrupted workspaces and such though.
I have been using it for more than a year now, haven't looked back at eclipse again.
One thing that bugs me about all of these options is that they don't work on Android itself. Not a big deal for me yet, but I see it becoming more important as we start to see Android devices with bigger screens and keyboards.
I know that AIDE is a decent IDE that runs on Android, but it only runs on Android and it doesn't compare with Eclipse or IntelliJ (yet).
I heard that the current version of Eclipse (4.2) enables some degree of GUI independence, and the next version (due in June) enforces that. That would be a good step forward, but still mostly a theoretical one.
If JetBrain were to undertake the rather large task of making IntelliJ work on Android, as well as existing desktop platforms, they would certainly get my $.
I wonder - is the new Gradle based build system compatible with Android itself?
I found the new-ish GAE Endpoints service to be quite interesting in that part of the build process (code generation) happens on the server as a service. This strikes me as very Googly and I wonder whether Google will provide Android build as a service sometime in the near to medium future. That would certainly help move us towards a platform independent future, though I guess AIDE has shown that it is not the build system, but the IDE, that is holding us back from developing on Android.
I've been using IntelliJ since just after I started Android development (2+ years ago). I had tried Eclipse before that, and besides the excellent feature set, always found the editor to be lacking in many ways (still no virtual space). So when starting with Android development I just hated it because I had to do it in Eclipse. No offense to the people who use and love it, I'm sure that it is a great IDE, it just does not suit me at all.
When I discovered IntellJ, I immediately felt comfortable within the IDE. This made me enjoy the coding that much more which, to me, beats out any feature that an IDE can ever have. IntelliJ has some shortcomings, but overall I find it an exceptional IDE for Android development. It can be a tad sluggish in large projects, but not to the point of annoyance. It is also insanely stable, and I have NEVER in 2 years of working with it had a single crash - just brilliant.
Also, having been using it over an extended period, I can safely say that they excellent developers at JetBrains have constantly been improving on the Android support within the IDE. Feature wise, I think that IntellJ is definitely almost on par with Eclipse, and they have done this without any official support from Google (as far as I know). If Google would take notice of IntelliJ and provide support (I'm thinking ADT) that would just make it even better - here's hoping.
I would highly recommend anyone attempting android development to give IntellJ a go - the Community Edition is free. Especially developers coming from Visual Studio
Thanks, tried it, but I prefer Eclipse.
I'm a new programmer (now learning), and it seems better for me now.

I think this is an important point. Try all the options available, and make a choice based on what you prefer.
I'm just glad that at this point Android has at least two very capable IDEs to provide that choice.
I really cant figure out how to get IDEA to see my install of the android SDK. It looks like their setup tutorial assumes default locations for jdk and android-sdk on windows. How do you setup paths if android-sdk is somewhere else? (using a mac)
Also, second link on the first post seems to be dead right now.

Check my answer here: http://stackoverflow.com/a/16485929/104891 .
I am on my second attempt at using IDEA for Android dev and I am stuck at the same point as last time, and its the only thing that Eclipse has going for it: I want to create a new Android app, min SDK 8, target SDK 17 (or whatever). This is fairly easy in Eclipse and I can go though the wizard for a new project, choose my settings, even the app icon and end up with the bare outline of my app that has the ICS style (ie an ActionBar & Holo theme)... can I hell do this is IDEA. I know that there is something I am/am not doing that is causing this but I have followed tutorials for adding support libs and even had a go at ActionBarSherlock.
I think this is where a lot of users are scared off of IDEA - I think its interface and usability is better than Eclipse, hell, the GUI editor for the layout XML files is better in IDEA than in Eclipse! (Eclipse freaked out on me several times trying to put static, non moving buttons at the bottom of the screen with a vertical scrollview above them, IDEA, sure, no problem!).
If they could sort the basics out, like getting the wizards included and even if they could allow you to add in various other frameworks (ABS, ViewPager etc) then they would have a winner.
On that matter, anyone got a tutorial on setting up a new project in IDEA the same as Eclipse with Holo theme?
Thanks
Hello, I am a computer science student and i need some help getting into android programming, i know a bit, but frankly it aint much.
I know C++, C#,Visual Basic,(I know C++ the most) and i am currently taking a class on Java, but I want to get into android programming too!(I made a game for android a while back using unity.)
I don't need a tutorial from the ground up.
I know how setup the environment, sdk, run, etc.
I want to learn how to work with layouts and make them look cool,
basic app functionality, work my way to internet connected apps, databases, apps with root, gestures, all that fun stuff.
I am just wondering if anyone would share any info or site that helped them.
I am not that much of a noob to programming but i am to the android sdk and a rookie with java.
if any mentor would step up or something i would really appreciate it.
Thank you.
btw if you're feeling bored check out my game!

Yes, i know its hard, i have a better version, i just haven't compiled and uploaded, i will soon.
I think best Website is always developer.android.com.
It hasn't only the API reference, but also Training section and much more.
Whenever I don't know sth I first visit this.

According to me you should go step wise step...Watch video tutorials on YT.
You can ping me for help.
Thanks
then go to java website and start learning java. Loads of tutorial stuff is on their website
java.com
then go and download the Android SDK in about 2-3 months when you've completed the above.
