I am currently reading beginner programing with java for dummies second edition by barry burd, when i finish should I start learning android (if so any recommendations) or more java (again recomendations greatly appreciated) tyvm in advance

I do not know of your personal motivations, but I would say that java is always a better choice for learning your way around. In Java, you can easily run and test your program, without having to worry with load times of emulators or having to look among the emulator's log window for your own occasional debug messages.
Doing so will not be limiting to you, in the sense that Java is a universe in itself (as is Android).
Android is a mobile platform easy to get started with though, but having a stronger background of how things work in Java will benefit you there, and that background will eventually be faster to achieve by using Java for a start.

Depends on how comfortable you are with Java at the end of the book. Much more important than just reading a book, is actually writing some code. Try to think of something that interests you, and write a program for it (400+ lines of code), and see if you feel like you're not having much trouble. If you are, more java, if not, you can go ahead and try the android API. Its not easy, mind you.

I'm quite new to the Android world, and, due to work needs, I'm trying to get in.
Whilst I'm not particularly afraid of the "thinking" code (i.e. Java), I'm a bit confused when developing the user interface.
Since I found that the simplest yet most effective way to learn something is copying from those who are the best, I'm wondering if there's some resource or something, out there, well done.
I mean: do you know some open source app, from which I can build my own knowledge about Android layouts? I wasn't able to do it on my own, even though I wondered quite a lot!
1) A good summary on everything UI design in Android can be found here.
2) The best place to get started is directly from the official website.
And here are relevant examples that are considered as good design in Android.

Where can I find a good thread/concurrency example app for android?
I see lot of examples using AsyncTask, but on android API guide is stated:
It is highly recommended you use the various APIs provided by the
java.util.concurrent package such as
Executor,ThreadPoolExecutor and FutureTask.
Therefore looking for a good app, that mixes all these classes.
Hi i started last month to develop on android platform (but I use java since 2008) so maybe my answer could be not totally correct. I'm my apps I use async task only for very short a sync operation and for the other cases I use threads and executors combined with broadcast receivers.
For good quality documentation about concurrency I recommend you the Sun/Oracle Jdk documentation. Standard jdk band dalvik have almost the same behavior, I said almost because dalvik was written mainly for embedded systems with low computational power and low resources in general.
http://docs.oracle.com/javase/6/docs/technotes/guides/concurrency/
Hope this will help you
You can download this sample project for use of threads and AsyncTask:
http://www.sgoliver.net/blog/wp-content/uploads/2012/07/android-hilos-asynctask.zip
The example belongs to the website www.sgoliver.net. This is a great website in Spanish and you can see many examples to learn programming on Android even if you do not know Spanish.
Hope this will help you.

I want to learn Android development and create mobile apps. What would be the recommended resources (There's too many on the web)?
Obviously http://developer.android.com/guide/index.html & http://developer.android.com/resources/index.html, this should be enough for starters.
If you really learn and exercise what's written there you'll have a very solid foundation. Many other pages might be good but that's where you should start because you'll always come back and learn something new.
As others suggested, http://developer.android.com/index.html should be the bible for learning android. Moreover, as the world of Android is too wide, I would suggest you to take up an idea (NO matter if it is very simple) and then try to search out blogs and tutorials on the particular features you want to implement in the same idea.
Even GitHub provides a lot of ready projects. clone them and try to understand the implementation by Googling the unknown packages and words.
This would give you a better learning experience.
Defiantly check out the blogs, they helped me so much! I also emailed the authors and they really provided great feedback. Also, when you have an app, ask your family and friends for advice! This blog helped me so much! http://www.droidnova.com/
Try Basic4Android, google it, i do not intend to spam. It will get you started with the OS and if you don't want to stay with basic go to java with knowledge.

I am interested in starting Mobile application Development.There are many suggestions on internet but,I wanted to have some starting guidelines from professional People out there like how they do it and what they use also
1.I want to develop Android Applications can you suggest me Simulator as well as good Starting Point(like links to tutorials)?
2.I have worked on c/c++/c# so is it going to be hard to learn Android?
I know this is a bit theoretical
question that may invoke long
discussions but i wanted to set
starting point not only for me but for
others who see this thread so that
they do not have to post question,Yet
get answer that how it is
professionally done
You need the android SDK (including emulator)
You should learn "android" as an operating system / middleware, but the applications are written in Java (using android SDK as well). The tutorials and documentation that are in the android developers' site are pretty good and will give you the basics, but you should learn Java in order to create applications on android.
Unlike other "Documentation sites", the android documentation is really really helpful and easy to understand for new-comers.
p.s. I am ignoring native code and C libraries in purpose.

I'm a Flash developer looking to get into Android/iPhone game development.
Android is more important to me, because I don't have any iOS device to test on, and I don't really like apple either :P (could you blame a flash developer for that?)
What is a good game framework for developing android games? Multi-platform is always a huge bonus but not everything for me.
I've been looking at Rokon and it seems ok, but the tutorials/examples are a little sketchy.
You should also give AndEngine a shot.
This question on GameDev may provide some insight. :)
If you're familiar with Flash, you might want to look into Adobe AIR for Android.
Now cocos2dx is also great ,it is in c++ so it give the FPS also you can easily port to any other OS. It is also difficult to start, after learn it provide more promising then any other engine.
http://www.cocos2d-x.org/
Thank you.
I like to use libGDX. Uses Java, documentation has gotten better, and quite a few games available for it.
