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!
Hello, I'm new to this forum, but, I have been in other forums relating to hacking 'mobile' devices. Previously, I was part of a number of different iOS forums, so, I know about jailbreaking, and troubleshooting problems on the iOS platform. I'll also share my few thoughts on Android, and my experience on Jelly Bean so far within this, embarrassingly long, post.
However, with Google's announcement of the Nexus 7, I was impressed by Android, and I was thoroughly impressed that it had finally sorted out the lagging problems. (I had used Android tablets, but they never appealed to me due to the lag which each one experienced. Jelly Bean, and, in particular, 'Project Butter', has remedied this issue - I have experienced no lag on my Nexus 7 since I received it a week ago.) And so, I pre-ordered the Nexus 7 - deciding against purchasing, a much more expensive, but, I believed, an excellent tablet, the iPad.
iOS, also, was beginning to become less interesting to use - sure, the iPad may have a larger scale of the iOS mobile operating system, but it remained largely the same. Same interface (although on a, admittedly, much better screen) same apps, same freedom - without the jailbreak. The new iPad (as advertised and sold by Apple), I thought, also did not do an excellent job on improving it's predecessor. Sure, an improved screen, and processor to power the screen - but is that worth it? (Considering another one will, inevitably, be released within a year.)
Tegra 3 was making strides. Although, one thing that saddens me about Android, and is something which definitely hinders it's ability to overthrow iOS - is the fragmentation present on the operating system. I'm not sure which apps are compatible with my Nexus 7, and which ones are not. (On a side not, piracy is also another factor which slows the progress of Android, and is perhaps a reason why some apps are exclusive to iOS in the first place - I'm looking at you Epic Games! Android certainly has the power and graphical capabilities to run the game, but Epic, like all companies must, are interested primarily on their profits. Again, fragmentation plays its part!)
Although, shifting to different mobile operating systems is rather difficult - especially since I am intrigued by modifications, and altering devices to make them fulfil my needs. On iOS, it was quite simple: There was only one thing to do - jailbreak. A process, which in itself, was extremely simple (for the most part.) It appears there are also much more iOS specialists on YouTube, who post easy to follow tutorials. Also, since iOS is a 'closed' platform, I was not concerned by viruses, and I knew what I could, and could not do.
Android, however, is open - and this, paradoxically, limits myself. There are so many modifications, I do not know which ones are good, which ones are bad, and which ones could result in bricking my, now beloved, Nexus 7. I don't want to completely mess up my device, or install random rubbish which only makes it slower. I have, almost literally, no clue on where to start. Sure, I've downloaded a few basic apps from Google Play - TegraZone - but who cannot do that without assistance?
I want to install more widgets, that amaze me, and also applications which will prove useful. (For example, a file managing app, a torrent app (no piracy! ), and other cool things.) I also, though, require a reliable anti-virus. Having previously used iOS for a number of years, I was not subject to any viruses, and, indeed, I did not have to worry about viruses - there are very few, if any, viruses on iOS. Android, though, is much more open to viruses. I need to ensure that I do not succumb to one.
However, what I am most interested in is the 'rooting' process, and the benefits which can derive from it. What extra things can I achieve by rooting my Nexus 7? What applications should I install to supplement the rooted device? (I have read of ClockWork(?)Mod, but I have not really ventured that far into applications which take advantage of rooting, since a lot of the information mentioned appears to me as gibberish, due to my noobishness .) And, perhaps most importantly, if something were to go tragically wrong - how would I recover the device. (Again, I'll make a reference to iOS, since, it is an operating system I am familiar with - you could simply restore the device through iTunes - what is Android's alternative?)
So, can you assist me in getting accustomed to the Android operating system by providing your recommended apps, and also useful tutorials which I can use to develop my understanding? I literally have no clue what half of the things in the Android section of this forum talk about - they included an abundance of vocabulary which, evidently, you need relative experience to understand. I also need require some Android experts - involved in perhaps development - to follow on Twitter!
Thanks for reading through my essay! Please, help a noob get started! I would appreciate all forms of feedback!
Note: I have downloaded the Android SDK (Although, not installed it, as of the time of writing.), and I have also got the factory image for the Nexus 7. I achieved this by briefly viewing a YouTube video. There do not appear to be that many, though. The XDA YouTube channel generally covers the news aspect of all things related to Android.
The greatest bit of advice I can give is to start here - Nexus 7 - and read read read!
There's no backup and restoring the entire system without root. When you do you can install a custom recovery. Note there is always a stock recovery that is far limited compared to recoveries such as CWM.
Android really doesn't have problems with viruses. Seriously. The only reason why it appears so is because idiots sideload apps from shady sites that contain viruses, but on iOS there is no sideloading without jailbreak.
For a file managing app, you can use Explorer (my preferance), ES File Explorer, or Astro.
Widgets are really personal preferance, I keep a music widget to quickly play music, a calendar widget, weather widget. You might want a news widget like Flipboard.
Rooting gives you full access to your device. It allows performance gains like overclocking, battery saving with underclocking. Like I said before, it opens to ability to backup/restore entire systems and individual apps with Titanium Backup. You can install customs ROMs, delete system apps (usually bloatware), remap the physical keys, use Tasker for automated tasking (pretty awesome btw). You can also edit system files, such as notification tones, ringtones, bootanimation, etc.

Welcome to Android!
I think you'll enjoy it
Ok on to your questions:
These are gonna be out of order
Reliable anti-virus: Trend Micro Mobile Security (worth the $10 )
Benefits of CWM: Backups, restores, custom ROM flashing
Benefits of rooting: custom ROMs, access to system files
Some apps to get started: Angry birds , Rom Manager, BatteryCalibration, ES File Manager, imo
Android's alternative to iTunes' restore is CWM. It's not official but its tons better then iTunes. You do it from the device and its a full, complete restore.
Ask again if I didn't answer something
Very long post BUT a few things to think about.
I have never used a antivirus software and really they are pointless just look at the apps before you download them read the comments and look at the permissions the app uses and think "does that fart noise app need to be able to send texts" of cause the answer is no so don't install it.
Other fractures can be useful like phone tracking but there are better apps that are free for this like prey.
If you root you will have full control of your filesystem much like su on Linux if you have ever used this. You could for example with root use my project to run Linux distros like Ubuntu. The nexus 7 due to being under googles power is very easy to unlock and root and if you mess something up easy to restore a backup. There are other great apps to like being able to back up apps and there data.
Just a few points and if you have more questions feel free to pm me

AVG or Avast antivirus are the best.
Solid Explorer is the best file explorer.
UCCW is the most customizable widget.
Taptu or Pulse are the best news readers.
Pocket.
Tapatalk forum.
MX player is the best video player.
Dropbox is by far the best cloud storage.
Photoshop.
PowerAMP is the best Music Player.
I would say that you don't need to root a Nexus Device. You got the latest OS and will always have.
The only reason you would wanna root is for some root apps.
Like Titanium Backup, AdBlocker and ROM Toolbox.
CWM is only necessary if you want to flash a custom ROM and you don't need to because you already have AOSP Jelly BEAN.
Thanks for all of the responses! And apologies for the long post! xD
I'll look through the Nexus 7 forums as XperienceD mentioned.
And by ClockWordMod - is that actually ROM Manager? I'm confused, and this is probably the most noobish question you'll get. xD
Since I don't really want to root my Nexus 7 (currently, that is) - then I would not really need to back up the data, since, there will be no risk. I'm not really concerned about overclocking my device - it's quite fast as it is. However, battery saving is quite tempting. Although, I don't see it as a reason alone to root my Nexus. And, as it is stock Google - there is no unnecessary bloat ware attached to the device.
And I can't get viruses while browsing through the internet?
I always thought that was the case, which is why I was looking for an anti-virus application.
Also, for UCCW - do I need to install a custom launcher of some sort? Is it really possible to add a widget, that appears complicated, simply through the Google Play market?
And finally, while installing ES File Explorer - I noticed that it had permission to remove shortcuts without user intervention. Is this the sort of permission I should be checking for on other applications? Since people on this forum recommended the app, I didn't really have any doubts of whether it was legit.3.
Also, how you I get toggles back on the notification bar? On iOS (sorry for the repeated mentioning of the scum ) - I had SBSettings, which was similar to the notifications available on Android. How would I add the toggles back?

It is a custom recovery which lets you backup your ROM, flash new ROMs and make other changes to your device (so in a way use it is a ROM manager)

This is true if you have a nexus device the need for root is far less, and the fact that alot of apps that used to need root have become features in new versions of android, back in the days of 1.5/6 you needed root to pretty much do anything good

Sure you might get windows viruses but in no way will they beable to run on your device let aloan harm it. The only way anything evil can be done is if you install the app (and in alot of cases give it root) so check those permissions!
anti-virus apps are the biggest scam (well paid one anyway) all they can really do is check a database of known bad apps and check it its there, other than that they do nothing. They are a trick from all the Windows users coming to android after having it hammered into them that you need anti-virus

Nope just add the widget to your home creen, in the app launcher press the widget button and then long press on the widget you want and drag it to the home screen you want, many apps include widgets so will be installed with the app as part of it (e.g twitter) while other 'apps' are just widgets

to add toggles you would either need to use a custom ROM, or download a app that will do it like this one https://play.google.com/store/apps/details?id=de.j4velin.notificationToggle&hl=en
Thanks very much for your detailed and extremely helpful reply!
I'll just do what you recommended! The Notification Toggle is an extremely impressive app, I must admit.
Since there is no point downloading a paid antivirus, should I download Avast Anti-virus (since it's free), just for precautionary measures?

Well its not going to hurt and would at least prevent an app thats bad be installed if you missed it. And like I said some do have some nice other features just the "anit-virus" side of it is rather pointless
There is a huge thread with skins for UCCW.
And Power Widgets or Notification Toggles are the best Notification Drawer toggle apps.
NT has customizable icons.
If you want weather too there's some new app called Deluxe Notification Bar which shows weather and toggles.
Look in the Nexus 7 forums for no-root battery saving advice.
And if you do not want battery drain don't use Anti-virus.
I've never had any virus problems.
If you're unrooted they can't really mess with your phone.
Just stay away from creepy apps, Chinese apps (no racist), piracied apps and apps from other than Play Store and XDA.
And never play ad-supported games.
Buy ad-free versions or play offline if you don't want battery drain.
Also SwiftKey is a MUST, if you're not happy with Jelly Bean keyboard.
