Android :: Best Practice To Parse A JSON Object On Client In Java And Droid?
Aug 25, 2010In 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?

Aug 4, 2010I am building an android app that needs to download and synchronise with an online database, I am sending my query from the app to a php page which returns the relevant rows from a database in JSON format.
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:

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.

Android :: RESTlet Tutorial App Does Not Return Java Objects (JSON Only) / Sort It Out?

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.

BTW, I am just using the server (GAE) in the example, not the GWT frontend.

Android :: Passing Around Object References In Java?

looks like this:

with a class a:
CODE:..........
The problem is, that i end up finding out that the values from newA are always equal to those from oldA. so i guess sth went wrong with passing the references of the objects in the last line of the loop...i thought java always passes references of objects unless an explicit copy() is called? if this does matter: this code is running on android - don't know if the dalvik vm messes aroung with this...

View 2 Replies View RelatedAndroid :: Java Settings Object - Serialization/deserialization
Dec 2, 2009(Code is for Android Actually, I need code to be portable between Android and Java SE.)
I want to have a "settings" class with various game settings, like
public int map_size;
public String server_name;
etc.
The data needs to be accessed fairly frequently (so members, not a key-value map), and from time to time de/serialized in some standard way (mainly to send it through network).
I want to be able to
Serialize and deserialize the object into XML or JSON, without having to explicitly write the code for every member (but still having some degree of control over the format).
Define some (constant) meta-data about every member (default value, GUI name, XML identifier, ...), in a way that allows for easy modification in the source code (I want to be able to add a new meta-property, define a default value for it, and not have to specify it everywhere else).
1 is achievable by using reflection. I thought Java annotations for class members would be perfect for 2:
CODE:.............
But it looks like (user-defined) annotations don't work in Android yet - code using them crashes the compiler...
What would be the easiest way to store the meta-data about the settings (or another way to approach all this)?
Store information about settings in some external XML file? Store it in a Java data structure, with content defined in the code? Defining the data in this way somehow seems very unwieldy, especially compared to keyword arguments of annotations?
Android :: Way To Store XML Data In A Java Object From A SAX Parser
Jun 21, 2010I have created a class with 3 sub classes in Java. The 3 sub classes contain variables to store information from my XML document. I am able to store in the first two for there are only single instances of the data in the XML. The third class contains variables that repeat multiple times. I want to store an object of "third class" objects. I also have a SAX parser class. I am doing this within an Android environment (1.6).
Does this make enough sense without displaying any code?

I have created Java RMI programs with a server and multiple clients, so I have a grasp of the concept. However with android I'm just not sure where to start.
What I am aiming to do is send some sort of information (could simply be text) to my computer and my computer will do an action. I have the GUI interface's and the actions to be carried out all worked out, just the sending of some sort of information is getting me.
Android :: Communication Between Java Client / Php Server App?
Feb 13, 2010I have a simple Java client application (Android app). I have to write a PHP server application which receives a request from the Java client application to write some data to a MySQL database or read some data from the MySQL database. It should respond with a status message (Write failed/success) or the data requested respectively. How would I get the Java client send a request and receive the reply from the PHP program and how would the PHP program receive the request and send the reply? I have googled about SOAP and REST architectures, but looking for a simple tutorial which will allow me to implement this simple program.

At this point, any changes to the mTiles object are reflected back to the tiles object.
Android :: Pass In Object Java Class Embedded In As Parameter
Apr 19, 2010I'm building an android application, which has a list view, and in the list view, a click listener, containing an onItemClick method. So I have something like this:
public class myList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
getListView().setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
/* Do something*/
}
}
}
Normally, this works fine. However, many times I find myself needing too preform an application using the outer class as a context. thusfar, I've used: parent.getContext(); to do this, but I would like to know, is that a bad idea? I can't really call: because it's not really a subclass, just an embedded one. So is there any better way, or is that considered cosure? Also, if it is the right way, what should I do if the embedded method doesn't have a parameter to get the outside class?
Android :: Reading Java Serialized Object That Has Been Split Across Two Files?
Mar 2, 2010I'm writing an Android application. One problem is your app cannot contain a file whose uncompressed size is bigger than about 1Mb. I have a serialized object that I want to load that totals about 2Mb. My plan was to split this file into two smaller files, then load the object by combining both files at runtime.
However, I cannot work out how to use e.g. InputStream and ObjectInputStream to specify that I want to read the data from two input streams. How can I do this?
For example, say my object was split between file O1 and O2. How can I say "Load the object by reading the data from O1 then from O2"?
