In my Android client I want to receive JSON objects from a server. By googling I found a lot of different possibilities how to best parse the InputStream from the Server, but most of them wrote their own parser. Isn't there a library which does this parsing for me? Or how should I best implement it by myself?

Tell me the best way to iterate through a JSON array?
I receive an array of objects:
[{json object},{json object},{json object}]
What is the simplest piece of code I could use to access the JSONObjects in the array?
Now that I think of it the method I used to iterate the loop was:
CODE:.............
So I guess I had was somehow able to turn the returned Json into and iterable array. Any Ideas how I could achieve this?
I apologise for my vaguness but I had this working from an example I found on the web and have since been unable to find it.
I am writing a simple Android app and have a database that will send back information into the app. I am new to Android and am looking for a simple example that demonstrates how the Android App can process a JSON response received from a HTTP request. I need to see what classes are used for Android apps to process a HTTP response. A reference to a good tutorial, or if you're keen, write a very basic method to do the job.

I've been looking the source code available from the Restlet official tutorial.
I am trying to hit the Restlet server using the Android app from he tutorial adn I only get the JSON response, not the Java Object. I tried using all libraries and extensions, nothing works. When I hit the tutorial url though (http://restlet-example-serialization.appspot.com/contacts/123) I get the desired response. Any ideas? BTW, I am just using the server (GAE) in the example, not the GWT frontend.

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....
}
I'm trying to create an app for Android that simply sends a command to an SSH server. No response needed, I just need to be able to send a command. I was wondering if there's any java library out there that I could use? No advanced stuff needed, just a pure connection to send the command.

View 3 Replies View RelatedI have developed bluetooth application where native library will be initiated by Java application (using JNI wrapper). JNI will call the entry function of the native library and then it will create Pthread to for scanning the device. Once Scanning is over, i will get the callback which i registered during the entry function of the native lib (called by app). But i haven't received the callback, but if i run the same native library in the shell (executable from the shell terminal) it is working fine. Can any one help me, if there is any specific architecture needs to follow while developing Java application based on native lib?
View 4 Replies View RelatedI'm writing a JNI library for a game. I have java code that I want to replace with functions from the library. Is it true that most of the devices out there are compatible with my code if I compile it for the default arm processor, or will I find that there are many devices out there that my library won't run on? What I'm asking is, should I maintain java code that does the same thing as my jni library for compatibility purposes, or is it safe to have jni libraries alone? How large is the group of devices that cannot use the libraries I write? Where are there stats regarding what population is using processors other than the arm processors?
View 2 Replies View RelatedI need to build a java.beans.PropertyChangeListener which is part of JDK (rt.jar) but not part of Dalvik.
Trying to copy the sources to my Application I get this:
Attempt to include a core VM class in something other than a core library. It is likely that you have attempted to include the core library from a desktop virtual machine into an application, which will most assuredly not work. If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine binary, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message. If you go ahead and use "--core-library" but are in fact building an application, then please be aware that your build will still fail at some point; you will simply be denied the pleasure of reading this helpful error message.
My solution: 1) build a core library with consisting out of java.beans.PropertyChangeListener 2) integrate that library (jar?) into my application.
My question: - how can I build a core library using eclipse?
