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 :: Call Webservice Using KSoap Simply Returning Error String

Apr 26, 2010

I'm trying to use ksoap to call a simple webservice. I followed this video to try to get started. When I call "getResponse()" on the envelope I just get the string "Error". There's no exceptions thrown or any other detail. I've successfully connected to a simple webservice I just setup on my local machine. Could this potentially be related to being behind a proxy server here at work? My code is below:

Android :: Android Remote Service Doesn't Call Service Methods

May 28, 2010

I'm developing a GPS tracking software on android. I need IPC to control the service from different activities. So I decide to develop a remote service with AIDL.This wasn't a big problem but now it's always running into the methods of the interface and not into those of my service class. Maybe someone could help me?If i now try to call a method from an activity for example start(trackId) nothing happens. The binding is OK. When debugging it always runs into the startTracking() in the generated ITrackingServiceRemote.java file and not into my TrackingService class. Where is the problem? I can't find anything wrong.

Android : Why Use Service For Background Tasks?

Nov 2, 2010

An activity can use AsyncTask or Handler framework for background work. Both will continue to work even after user has moved away from the activity that started them and the onDestroy for the activity has been called. In other words, an activity is fully capable of doing background work even after its GUI has been shutdown.In this scenario, use of Service for background work seems like redundancy. What does Service bring to the table that an activity can not do?

Android :: Start Background Service On Install

Oct 22, 2010

I have an app which runs as a background service only. I'l like it to start up when its installed. As its just a background service it doesnt show up on the pane of installed apps. So there is no way for the user to manually start it. I've already regietered for the BOOT_COMPLETED intent which works but I dont want the user to have to power off the phone after the app has been installed, just so as they can start it.

I've looked at the following intents: ACTION_PACKAGE_ADDED/CHANGED/ REPLACED/RESTARTED/INSTALL, ACTION_SCREEN_ON/OFF, ACTION_USER_PRESENT, ACTION_TIME_TICK,

But it doesnt seem that you can register to listen for them from my manifest.

How I can start my background service without a power off/on?

Android :: Background Service - Intents For Communication Between UI

Jul 6, 2009

I'm writing an application that consists of a background Service and one or several Activities acting as UI towards this. There will most likely be several different UIs for this service that will installed later on, like custom widgets or UIs. The question is how to solve this in the most efficient way. Is it better to only use Intents for communication between UI and Service (sending control commands with Intents from the UI and listening for Intents from the Service for state and data updates) or should I prefer using IPC communication (AIDL -> Java Stub, binding to the service etc.)?

Since the UI might be started long after the service is started, I would either need to use sticky intents to signal current state, or have a very frequent intent sent by the service if choose to go with the Intent-based design. Which one would be the preferred way in that case? I've read that sticky intents are much more resource consuming than normal intents, but are intents more consuming than IPC directly towards the service? Also, is really an AIDL the right way to allow third-party integration? Intents sounds better, since they are also asynchronous.

Android :: Running Background Service That Would Disable SMS

Jun 25, 2010

I'd like to include a feature in my application that would include a running background service that would disable SMS, if certain conditions were met (location for instance). Is there a way I can intercept the user wanting to open any SMS app and block it? Would a Broadcast Receiver be able to do the trick? Maybe a different way to go about this?
