First you will need to learn Java. This is a great book for that purpose: http://www.headfirstlabs.com/books/hfjava/
I learned Java with it myself. It is good for beginners and in no way reading it is boring!

There's a good series of 200 video tutorials for beginners made by thenewboston, it's quite good and it will show you how to build a dozen different applications with different purposes (i.e a stopwatch, an internet browser etc...). It will give you the basics of the Android APIs & the xml part of the job along the way.
Plus they're short videos so you can watch one when you have a few minutes anytime.
Here's the playlist with the 200 videos : http://www.youtube.com/watch?v=1j4prh3NAZE&playnext=1&list=PL33384E9848C4F55E&feature=results_main

I've looked through several books for beginners, and I think "Hello, Android" by Ed Burnette is the easiest to start with.

Need Suggestions

HI i have android app development experience for 2 years.
I understand the framework but when it comes to typical situation when i think it would have been better if more android internals were given or more documentation was available.
So my question is for app developers what is the next stage for learning in android development So that we have deeper understanding of the framework and solve typical issues as well. for eg
Activity finish() dismissis and removes the dialog in that activity but i could not find any docs regarding this. so i was in dilemna what to do?
Please help how to advance more into android and if possible please give links to study material or links where i can get a path
Thanks

So this was the question I got after my all app compiling and decompile for 3 months.
So I was just a app modifier,and I thought about being app developer,I mean creater.
So I googled and learnt the coding(toughest part) and iam now a good developer who is on the way of development.
And for ur question finish();
All those datas are in java format packed as class.dex,you must open that to see the source file as java.
However u can see .smali file wen u decompile any app which you/me/ can't understand....(those r derived from java)
Offff good question:thumbup::thumbup:

My number one snag I would do, if I could go back to when I started, would be "Learn what a Context is, and the different types" which coincidentally relates to why a dialog hung of a context does disappear

Hi,
Stackoverflow.com is a good source of information to resolve doubts.

Develpoing GUI in Java

Hi everyone,
some days ago, i was substancially forced to join an Android project by my professor.
The fact is that his course was about C++ (your equivalent of that course should be Compuer Science II, and i have a good knowledge of C++), and this project is in Java. I have a little experience in Java (in fact, one of the courses that i am attending is focused on Java). Now, i think that in order to be a Computer Science engineer i have to fit myself to the situation ( i have some docs about the project) but i have no experience in Android app development and a very little knowledge of XML, so i ask you some help :good:.
What i have to do is to realize some GUI for his application. It is not very difficult, but i have no idea about from where i have to begin. In these 2 days i have managed to start some very simple application from Eclipse on my smartphones, but that's all, nothing more. So, is there any book or (better) some short guide or video to follow?
I use, as IDE, Eclipse (because i usually use it for Cpp, but some people said me that Android Studio should be better). I know that Eclipse is a really god IDE (For Cpp i tried also CodeBlocks, VisualStudio and Netbeans), but i know too that it raises some error that newbie user could not managed to solve easily: one of them is a java.lang.nullPointerException raised in every main.xml file...
Moreover, the project has to connect to a IBM Bluemix-stored database.
Last but not least please share a comment about my English (that, i have to admit, is not very good). I would really like to know how it - really - is.
(Excepting the typo in the thread title).
So, i ask you to kindly share resources (video, guides ...) about realizing GUI in Android.

Well first i'd recommend using android studio since it is the official ide for android by google, and I have worked with eclipse for 2 years and the android plugin is just too buggy.
About designing the ui it is usually done in xml rather than in code since its more intuitive and there is a preview.
You should start learning the basics and from there they teach you how to design the ui.
Try the official guide in the google developers section for android "developers android training"

Are you talking about https: //developer .android.com /training/index .html ?

Yes exactly, they have some nice guides there.

Here is a very nice guide for creating your first app in Android Studio: http://www.raywenderlich.com/78574/android-tutorial-for-beginners-part-1
Here is a layout tutorial: http://code.tutsplus.com/tutorials/android-user-interface-design-layout-basics--mobile-3671
Here is a compilation of Android beginners tutorials: http://www.sitepoint.com/12-android-tutorials-beginners/
If you give a more focused description of what you are trying to achieve (what are you intending to display and how do you want to display it), more focused tutorials can be suggested.
Best of luck

You can take a look at vogella web site tutorials
They have very usable tutorials, easy to understand.

[Q] Extract JSON data and display in ListView with Searchbox

Hi Everyone,
I am currently a very new starter in the Android App Development stage. I have tried to develop a ListView with Searchbox facility to search data that comes from a specific URL in the form of JSON data. I managed to understand displaying this data in ListView, but adding a search facility is something I'm struggling to grasp somehow.
The code attached is a reference code I am trying to tune before I move on to actually developing my app. However, it doesn't seem to work on the emulator, giving me the error that the MainActivity file has stopped working.
I am unsure if there is a fundamental error somewhere, and would be really grateful to get some advice on this. I have looked online and can't seem to find a good resource that explains merging ListView with JSON data effectively with a Searchbox.

You should implement the search on the listview adapter, not on the activity itself.

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. Inbox for any further information or quote back
**********Hit thanks if I helped you***********

You need the JDK. Please read the instructions on the download page. Under the section 'Requirements'
