Android :: How Much Java Should I Have Learnt Before Trying Droid Programming
Jun 5, 2010
I have been seeking beginner learning books in Android, and of course found out that I should learn Java first. So I began studying Java and now I am quite comfortable with objects, classes, inheritance, interfaces, and just moved onto Layouts in Swing as well as Swing Features. But I am starting to wonder.... do I know enough about Java now? Can I start programming Android yet?
Of course I can keep going in Java, but have been itching to begin programming Android apps.
Any definitive answer here about how much Java I need to know before Android?

I've recently knocked up a server/client app for Windows & Android that allows one to send a file from Windows to an android phone over a socket connection. It works great for a single file but trying to send multiple files over in a single stream is causing me problems. I've also realised that aside from the binary data, I will need to send messages over the socket to indicate error states and other application messages. I have little experience with network programming and and wondering what is the best way forward.Basically the C# server side of the app just goes into a listening state and uses Socket.SendFile to transmit the file. On Android I use the standard Java Socket.getInputStream() to receive the file. That works great for a single file transfer, but how should I handle multiple files and error/messaging information? Do I need to use a different socket for each file? Should I be using a higher level framework to handle this or can I send everything over the single socket? Any other suggestions for frameworks or learning materials?

As the title says i'm new to the Android community, and i don't have much experience on the development side either. but i am very interested in getting started. I see that Android apps are based off of Java... So would it be better for me to learn Java before getting started with the SDK and eclipse? Or is it just the same to jump right in on App development and learn on the fly?

I have made apps for the iPhone, but want to also code for the Android but want to know if it is first worth my time, second worth my having to learn another language, and third worth the effort in the sense that am I going to make a profit from this. Also if in any way Android code is similar, then will it be hard to bring the iPhone (Xcode) files, or copy and paste my iPhone code into the Android code.

Essentially Im trying to get many many java clients connect to a socket on my ColdFusion server (Using the Socket Gateway). However before i even start to code this, Im a little confused about sockets and their performance. First of all, are sockets meant for many(1000+) clients connecting to one socket (say port 2202) on one server? How is the performance if all there waiting for is basically a ping, or something such that when these clients receive this "ping" they can go get some new data.

Are there pitfalls or the points to remember while programming for Android? I think the list will include topics on Multithreading, Persistent Storage, etc.

Which programming languages can I use on Android Dalvik?
Mostly, Android applications are written in Java. But i heard that its also possible to use Scala or some other languages. And I also read that it's possible to include native C/C++ code.
Is there a reference/list available that shows which languages can be used?

I'm new to game programming. But I've got an ide for what I think would be a fun game for the Android platform.
My question is, where do I start? Anyone got some good sites to recommend or perhaps a book or two. I've got medium skills when it come to programming but iv got a masters of science degree in computer engineering so I'm not totally unfamiliar with algorithms and stuff.

Basically, I don't know what functions & XML attributes to provide when programming a specific Android feature; eg, Android Search Widget with Edittext in the middle, magnifier glass on the right, and a custom icon on the left.
From where I can find out what methods, parameters & XML attributes to call when doing a specific Android task?
Fron what sources can we find out how to program specific Android feature? Are there some overall programming pictures to reference?

There are the following layout options to create interfaces for android.
AbsoluteLayout
FrameLayout
LinearLayout
TableLayout
RelativeLayout (and some more)
Which of the following is most suitable for designing simple games? Guessing that the absoluteLayout is easiest, but will it be problems with different screen sizes? What do you recommend?

I have a some strange issue. I would like to get the package name of the current home screen. lets say we have two home screens : 1. default android home theme 2. 3rd party home theme. Assume both are installed and current home theme is 3rd party home theme.
Now I would like to get the package package name of the current home theme (3rd party). Is there any api which can give the current home screen package name? I can get the package name in ddms. But I want it pro grammatically.

Can anyone recommend a good Beginner Android programming book? When I was in college about 20 years ago I used to program a lot (Basic, Pascal, COBOL, Fortran). I dabbled a little bit in VisualBASIC about five years go, but it was really a hack. Now, I really have a burning desire to write some applications for my Android phone, but I really don't know anything about all the new programming technologies (OOP etc). I'm looking for a good book that will teach me modern programming using Java and the Android platform.
I've seen good books on learning Java 6 and some good books on programming Android (but they all seem to assume you know Java or C), but nothing that seems to combine the two. I'd really like to learn Java right on the Android platform to begin with if possible. I know there are a lot of resources available online but unfortunately much of the time that I will spend on this endeavor is when I won't have internet access so a good book would go a long way.

I have a little idea of the Utility Classes with a slight doubt on demand.
If I use a Utility class in my Application than to use that class in my main Activity do I have to create the object of that class or I can directly Import that class in my main activity?
In the nutshell, all I want to be clear about is that basically how can I use the utility class in my Main Activity?
