I am trying the application program using json.what is the uses of json_decode in android.How can i use the json_decode in my application? is it possible means tell some idea.
I think you'd be best to ask on a forum like App Dev Forum or similar as this is not the sort of question we like to answer on StackOverflow. You really need to research these things yourself or give us a code snippet for us to check out. This is more of a strictly programming related community.
It would be MUCH easier if you used GSON. It automatically maps JSON to your classes.

Now I am researching how to implement email-based sing-up in Play Java. However, I couldn't get any useful information, so can anyone tell me the information? In other words, can anyone show some links or the easy example of it?
This is the example written in Scala, but unfortunately I can't understand well, I am not familiar with Scala...
Any comment is welcome.
EDIT: Some people dislike this question. Maybe they think this is not a good question because I am supposed to reach some answers of this question.
However, in fact there seems to be no information that help me build email-based authentication when using Java. In Play Scala, you have many options. But I want to know how to realize it in Java, not Scala. So, this question is so meaning for some people who try to build a web app in Play Java.
You can do this using the Play Authenticate library: http://joscha.github.io/play-authenticate/
I was wondering if anyone knows a good tutorial that explains how to use SQLite with libgdx. All the ones I have found don't explain it well and I'm having trouble figuring out how to use it. So if you know of one that explains everything decently please give me the link to it. Thanks in advance.
Notice that the extensions available won't work for multi-platform, at max you'll be able to support Android and Desktop. My advise is for you to create your own classes for methods for accessing info stored as files on the device trough the LibGDX File API. You won't get to use SQL and it will certainly take longer but you'll get try multi-platform support (if that is what you're looking too of course).

Try this, although it is rather a suggestion of implementation rather than a full blown tutorial.
A Libgdx user proposed an SQLite extension several months ago. Its definitely a work-in-progress, but might be a good place to get some ideas or borrow some code from: https://github.com/libgdx/libgdx/pull/222
I know this question has been asked before, but that was several years ago, and of the two answers, Rome and Abdera, the first no-longer seems to be maintained (there aren't even any download links on the website, nor can I find documentation). The latter also appears rather complicated, and neither appears up to contemporary standards of Java library design.
Are there any new alternatives out there that are well designed, and well maintained?
Sorry, I do not know of any library, but, that said, seeing as RSS is an XML format you should be able to roll your own using SAX/JAXB/DOM. Which one to use depends on whether you wan ease of integration with Java (JAXB) or speed (SAX). There is a middle ground in DOM.
RSS is not a complicated format so I think you could just develop the features you need as you come across them and it'll be faster (and the skills you learn more transferable) than exhaustice searching for a library if one cannot be found easily.
Hope this helps.
I did find this class RSSDigester. It might help, I don't realy have the time to investigate it right now, sorry.
RSS reading hasn't really needed changing for some time. ROME really is quite nice, and as far as fetching it you can get it from http://download.java.net/maven/2/rome/.
I eventually found HorroRSS, which is exactly what I was hoping for. Its simple, easy to use, and appears robust.
I came across open-source project PHP/javaBridge for connecting php application with java. But why should I use java with php? Is there any specific advantage for this? Thanks, Robert
The main benefit is when you already have a lot of existing java libraries that you don't want to recode in PHP, but where you do want to build new applications using PHP
You may want to use a library that is in Java.
You wanna find the right tool for the job, not the right job for the tool. I guess you just shouldn't use it if you have to ask this question.
That said, there are a few good cases where you'll use Java with PHP, most of the times the big advantage is that the Java application keeps running on the background (as a daemon) and it's more powerful.
Do you really need to use Java? If so, go for it. Or are you just looking for new ways to do things? If so, don't bother. PHP is powerful enough to do what you need. So is Java. Pick one, and stick with it...
Is it possible to develop iphone apps with java? I'd prefer to use alchemo over xmlvm because of the superior features that it offers. Can I do that? Is anyone else doing that? I've looked all over their site for the download link, but can't find it! Is it available? If so, where?
http://www.innaworks.com/alchemo-for-iphone-java-me-j2me-to-iphone-porting/
Is it possible to program with Java? Yes. There are also implementations of C# with Mono that work (kinda) with the iPhone.
Is it ideal? Probably not. Objective-C really is the first class citizen on the iPhone and the majority of information, resources and help will be centered here.
As for alchemo? This looks like one of those times you will actually have to contact New Zealand if you really want more info.
