What are the top 3 books for application development?

Hello experts,
I would like to start developing android apps to push to the android market to make some cash. Could anyone who has experience in doing so recommend some material / books that I could start off with to learn android application development?
Thank in advance.

I'm also interested. But I think you also have to specify at what level you program already. What languages your program in or if you're a complete beginner, like moi hehe, in order to get adequate recommendations

i just walked into a book store and picked up idiots guide to android, idiots guide to java, and a cup of coffee.... form what i can see, alot of app developement happens in java (or the tutorials i've seen are by people who prefer java) so I just figure i start this way... also, elicpse looks like it could do many diffrent languages so as long as your version does the language you know (should you already know one) you should be golden...

Great! Thanks for the feedback guys!

My top book is Commonsware's The Busy Coder’s Guide to Android Development

Any game developers here?

If so can you point me in the direction of what the best game there is to develop 3d android games, what dose game loft use?
I can use unity3d but they don't officially support android yet, im more into the 3d side of things, but i have some coding mates.
ps: that head and shoulders add is so annoying covering the text boxes

Get the SDK & Eclipse, then learn to code Java.

Like the previous poster said: Eclipse + Google SDK to start (under Windows 7 here): http://developer.android.com/sdk/index.html
Java to start your application then when you need more speed: e.g. for your 3D engine, you can use the NDK (also provided by Google) to add C/C++ modules.
You can also get a Samsung Tablet Emulator to add to Eclipse here: http://innovator.samsungmobile.com/galaxyTab.do

Thanks. Guy's, ill check it out

What language and software uses android for programming?

Hey guys im considering porting/recoding an app from VB.net to work on android, but i havent got a clue what language is used in android, could someone tell me its name or some sort of website with this information?
Finally if someone is experienced in programming apps for android, i would like to chat about a few capabilities of the language.
Thanks in advance!

Android is Java-ish based.
i would recommend you checking out the program Eclipse.

The main applayer is java based with some xml thrown in. But there is a native development kit that you can compile c c++ and many other languages to run on an android phone. But since java is virtual machine based an app written in java will run on all phones*(some caveats like os version) while the app in ndk will work on only hardware that it was designed for
Also, is Google not working? A simple search for "Android programming language" would answer this question

hmmm, yes there is google but not what im exactly asking, and that makes me ask this:
You talk about c & c++ and other languages compilations to run on android phone, is vb.net a part of that list?
Could you show me a website or something that says more about that dev kit? im basically trying to port my apps from vb 2010 express (windows forms based) to android and if that thing is not possible should i use java to code it all over again?
Thanks in advance!

http://developer.android.com/sdk/ndk/ this is for the ndk but it is not as simple as just compiling your code with the ndk. You will need to rewrite some of it to actuallytie into the android apis
You should really just use the java sdk. You will reach more people and be able to find more help and info
And I stand corrected, while there are projects trying to bring other languages to the ndk it is at this point just C and C++

oh well in that case i will need to learn java.... thanks mate, i think its easier to just rewrite the whole thing really i like proper optimizations and ports most of the times lack them.
Thanks for the information thats all i needed.
PS: rep added

if you know vb.net well you'll have no real problem with java.. it just adds brackets and semicolons essentially lol. I learned java in college and then was thrown into the .net framework using c# and i love the .net framework.. its so hard for me to go from using Visual Studios to Eclipse to make an android application because Visual Studios (which im assuming you use, is so powerful).. But yes android is java code behind and html (preferred) GUI. You can make your GUI using java but trust me its terrible!

Html? You mean xml?
Also try Intellij instead of Eclipse. Eclipse is way too bloated and IntellJ has some amazing autocomplete features. Its better in my opinion

what?? i really need a proper GUI ugh... yes im using visual studio, and indeed is amazing, the app i have and i want to port to android is windows form based, the most essential thing i would need about it is the calendar control :\

You can use Javascript+HTML5 (it's complicated to express here but the whole things is pretty much native).
Python aswell, use SL4x or Kivy (Kivy is pretty good but it's still too new).
Sorry, being hate Java too much.

ok np, so to doublecheck this: to have an application with graphical interface i will need javascript and html5?

I dont know why people spread extremely non standard practices to people getting started...
No you dont need javascript or html5.
Android has a ui layout system based in xml. Its just there to arrange objects that you can access from the java code. So a little xml and java is all you need

The right way to do GUI is with Java, with the official SDK from Google.
Some non-standard way to do this is with Javascript (just a GUI wrapper from Javascript to Java) and Python (again wrapper to Python).
You can choose which way you want, many people I know didn't like Java, and they choose to use a web application, and then they want to embed this to a native Android application, so they go with Titanium Mobile or some others framework like that. It's not as good as Java, but it's some other way to start with your application (Web app first and then Native app)

i feel like i should probably stick with java, i want it to be quick and fast and have alot of stuff to code, the program should run in background so it must not affect performance at all, will use timers with a basic code ticking every second while on background and thats it really

Then use java bro, it's an awesome programming language, I don't know why some people don't like it, each programmer should learn to get used to each language.
Anyway, for likes.. colors

well ive been learning vb and i will admit that im still on intermediate level, even though i know all the basic stuff such as messing with its own functions, etc i still havent used any of the apis for it, the main problem with programming is that if u learn a language you would waste your time learning that one or else if u go learn to many languages you will end up not knowing none of them at all.
Ill see if i can mess with java, some people say syntax is a bit similar to c & c++
EDIT: btw, im not saying i dont find java good, a programming language that will basically run on any machine independently of the OS makes the language itself possibly the best and most versatile around.

I'm learning Android and I use Java and XML. I'm still a beginner though.

I am just curious, software like Titanium Backup, or Angry Birds, which programming language do they use? Could this stuff be programmed with Eclipse in Java?

[Q] communication between android app and java application

Hi all,
Im new in this forum and just wanna ask for some help on where can i find a simple tutorial or a sample project of an android application that can communicate with a java application on a PC.
im thinking via wifi.. also i got some knowledge in java programming and right now im starting to learn more about android development.
some simple tutorial/samples like an android app where you have to type a message and it will show on the java application in the PC when the send button is clicked.

You probably want to check out Google App Engine and their Cloud Messaging and datastore features.
It would be better than WiFi or Bluetooth as you could be the other side of the world.....

Help Developing An App

Morning all,
I have never created an app, but decided to look into it late last year. I began work on an app around September 2014, did a little work every weekend, and haven't really touched anything since November.
I have experience with HTML, CSS etc (I can write them). I can also have a basic understanding of other codes such as PHP, JavaScript, Java, C etc - basically, enough that I could take some code and edit it to suite.
I was hoping that creating an app would a) help grow my current business and b) give me a new challenge to learn new code.
Anyway, I'm really stuck on what to do. I downloaded Eclipse at home, but my laptop is on it's last legs. I have been creating the app at the office, using Adobe Flash Builder 4.7. I read a few tutorials, and downloaded some sample apps to learn from (as part of some of the tutorials). However, none of them have what I want.
My App Idea
So, enough waffling on, I'll try and explain my app without giving away what I want to do.
Basically, the app will be one where users can enter an error code, and press search. The result would be a page showing the description of the error code, and then what the solution is to fix it. There is then potential to add a "buy this part from" link which will suggest suppliers to visit.
So, as an example, let's say a user got a Blue Screen error code on their PC of "ABC1234". They would enter that code into my app, and the result would say something like:
Code: ABC1234
Description: RAM Error - overheating
Fix/Solution: Replace RAM
What I Have So Far
Other than a couple of test files that I've been learning with, I don't have anything solid in terms of an app. What I do have though is an Excel file with 889 error codes and what each code means.
What I Need
So, I guess what I need is either:
some help/guidance on how to create an app that in it's simplest form is a home page with a search box, and then 889 pages in the background that return depending on the searched error code.
or, someone willing to help me develop such an app

Firstly, download Android Studio - Don't use eclipse anymore
Secondly, here is a tut on using an older version of Android Studio
Have a go, see how you end up. Let us know, if you're really needing help, ask here again

Thanks,
I'll have to try that once I get home as the IT Administrator at work has to vet everything that gets installed.

Thanks sir but do we have a highly compressed Android Studio? 800mb+ is such a big file to download.

Like minooch said, install an IDE, understand how it works and then try some tuts on Internet to learn how Android works. What you want to do isn't really hard, you'll manage quickly to do it but you will be prouder if you do all by yourself.
Some hints : Don't go coding directly, try to organize your project (data structure, classes, methods) before starting to code. On a small project, it's not as important but if you start doing things well now, you'll thank yourself in the future

Hello.. You just cannot make a app like for such kind of work. You have to make make a website server for the same and then make a app for it. I know a technique for such kinda work.Web crawling us your answer. If you could setup a website for that then I can make a app for that easily within two days.
