Android :: Client Connecting To RestFul Webservice

Nov 10, 2010

I have been fed up of looking for a simple example of rest webservice connecting to Android Application. I know so many people have asked this question before, but there are so many different answers as a theory.
I know I must use restful web-service, rather than SOAP for mobile applications.

I need to create a webservice which is producing JSON, then in Android I can parse the JSON, but the problem is that as I am new to android I am looking for a simple example with both Server and client.

A server : JAVA with Database connection and Restful WebService that produce JSON

Android Client : which parse the JSON result from the webservice

Android :: Call .NET Webservice

Jun 7, 2010

We have a SOAP webservice that is used for an iPhone application, but it is possible that we need an Android specific version or a proxy of the service, so we have the option to go with either SOAP or JSON. I have a few concerns about both methods:

SOAP solution:

Is it possible to generate java source code from a WSDL file, if so, will it include some kind of proxy
class to invoke the webservice and will it work in the Android environment at all? Google has not provided any SOAP library in Android, so i need to use 3rd party, What about the performance/overhead with parsing and transmitting SOAP xml over the wire versus the JSON solution?

JSON solution:

There is a few classes in the Android sdk that will let me parse JSON, but does it support generic
parsing, like if I want the result to be parsed as a complex type? Or would I need to implement that
myself? I have read about 2 libraries before here on Stackoverflow, GSON an Jackson. What is the difference performance and usability (from a developers perspective) wise? Do you have any experince with either of those libraries?

Android :: Prepare The UI From The Webservice

Aug 30, 2010

Playing around with the UI and SQLLite for a while and it looks pretty good to me . We have a requirement that for the App that all the questions would be coming from the server through REST / Web service which would be displayed on the App..

say for e.g if there are 4 questions
1) Enter your Name -- Text Box
2) Did you sleep well last night -- YES / NO
3) How many hours did you sleep - Text Box
4) How did you hear about us -- Drop down

So the requirement is that the Questions would be displayed on the App after doing a SYNC with the server during the SYNC with the server the Questions would be downloaded from the SERVER through REST / Web service..if the phone is not connected then pull the questions from the Database...

These questions are simple questions and they change quite often and we have a similar app which is there for iphone which does this ....

Android :: Custom Namespace Using .Net Webservice And Ksoap

Jun 1, 2010

I am calling a web service which has the following request format.


Now when I call the web service I get the following error SoapFault - faultcode: 'a:DeserializationFailed' faultstring: 'The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter

The InnerException message was 'Error in line 1 position 463. Element ' DataContracts:InFields' contains data of the ' DataContracts:anyType' data contract. The deserializer has no knowledge of any type that maps to this contract.

Add the type corresponding to 'anyType' to the list of known types - for example, by using the KnownTypeAttribute attributre or by adding it to the list of known types passed to DataContractSerializer.'. Please see InnerException for more details.' faultactor: 'null' detail: org.kxml2.kdom.Node@43bcb040

The Request sent is has i:type="n0:anytype" in each tag which is creating an error in server side. How do T remove the attribute from the XML tag of the request XML for example <n0:ExServiceDataField i:type="n0:anyType"> should be as <n0:ExServiceDataField>

Android :: How Have To Be A Webservice For Use - Limitations - Paramters - Return

Nov 14, 2010

I have a android APP that needs a remote Database, to do INSERT's and SELECT's.

I will use a webservice to comunicate with the remote database, the webservice will be installed in the server side, with the remote database, and webservice will do the SELECTS and the INSERTS and will return me XML data. But i dont know anything about webservices, then a friend will do it.

But my friend need's to known if there is any limitations making webservices for Android. I search on google for days but all i am finding is very complex and i can't find the answer to these three questions:

Webservice needs to be created with a special way? Webservice remote functions can have parameters? (i need to give to the webservice parameters to do the select's or the inserts of data) Webservice can return results in XML normally or needs a special way to do it?

Android :: Parsing A JSON Response From A .Net Webservice

Apr 21, 2010

Just to get this out in the open I am new to JAVA, KSOAP, and JSON. So I'll try to explain this the best I can.

A while ago I created a webservice to be consumed by Blackberry Apps that we're built using the plug in for Visual Studio. Now the project I am working on, I want to consume the same webservice for Android devices. For the most part I have the base code for the Android app done and working. Here's my problem:

I can successfully call the webservice and get a response. I know from creating the webservice that it sends a JSON response. My problem is trying to parse through the JSON response. I have found a few examples that I have been suiting to my needs however I am hung up on one thing.

In the JSON each element is preceeded by "anyType" which is forcing my code to return no results (Ultimately I am binding the data to an ArrayList) Here's what I get if I "getProperty(0).toString()...anyType{Artist=anyType{TrackName=Champagne Supernova;};

Here is the code I am using to parse the JSON Object....


WebService Code:


Sample of XML Output from a browser:


I have a feeling I will need to implement a Class, and Getters/Setters on the Android side. I'm just not sure how to go about doing that.
