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

Aug 25, 2010

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?

Android :: Parse JSON Into A ListView Friendly Output

Dec 30, 2009

I have this JSON, which then my activity retrieves to a string:

CODE:......

It can be accessed here as well, although it because it's quite a long string, I've trimmed the above down to display what is needed.

Basically, I want to be able to access the items from "items_last_week" and create a list of them - originally my plan was to have the 'thumbnail' on the left with the 'item' next to it, but from playing around with the SDK today it appears too difficult or impossible to achieve this, so I would be more than happy with just having the 'item' data from 'items_last_week' in the list.

Coming from php I'm struggling to use any of the JSON libraries which are available to Java, as it appears to be much more than a line of code which I will need to deserialize (I think that's the right word) the JSON, and they all appear to require some form of additional class, apart from the JSONArray/JSONObject script I have which doesn't like the fact that items_last_week is nested (again, I think that's the JSON terminology) and takes an awful long time to run on the Android emulator.

So, in effect, I need a (preferably simple) way to pass the items_last_week data to a ListView. I understand I will need a custom adapter which I can probably get my head around but I cannot understand, no matter how much of the day I've just spent trying to figure it out, how to access certain parts of a JSON string..

How To Parse Complex JSON

Feb 27, 2012

My app sends a request to a php script on my website and the php script sends back a JSON string like this:

Code:
{"route": [
{
"summary": {
"leaveat": "11:58",
"arriveby": "12:23",
"duration": "25 mins",
"transfers": 1,
"fareA": "1euro",
"fareC": "0.8euro"
[code]....

The main tag is "routes", it contains "route" which is an array of objects consisting of a "summary" and "sections", "sections" is an array itself.Well, what I need is to parse this JSON to be able to write details for each "route" such as:

-duration: 25 mins - transfers: 1 - fareA: 1euro - fareC: 0.8euro - Station1/11:58-11:59 - Station2/12:06-12:23 - Station3/x
-duration: 40 mins - transfers: 2 - fareA: 1.4euro - fareC: 1euro - Station1/12:03-12:20 - Station2/12:21-12:25 - Station3/12:28-12:32 - Station4/x"

I'm trying to do this from yesterday and I can't find the way to read the data from the JSON string.I've tried with getJSONObject() and getJSONArray() in many combinations, but no the correct one.Since I've tried many codes, I think is useless to write here what I tried.I've removed the outer "routes" which actually was useless, but I yet can't parse it.

Android :: JSON Array Iteration In Java

Aug 4, 2010

I 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:

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.

Android :: Need An Easier Way To Parse XML In Java?

Nov 12, 2009

I'm trying to figure out how to parse some XML (for an Android app), and it seems pretty ridiculous how difficult it is to do in Java. It seems like it requires creating an XML handler which has various callbacks (start Element, end Element, and so on), and you have to then take care of changing all this data into objects. Something like this tutorial.All I really need is to change an XML document into a multidimensional array, and even better would be to have some sort of Hpricot processor. Is there any way to do this, or do I really have to write all the extra code in the example above?

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

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.
