I am trying to comsume a self-hosted WCF service which simply returns a String in JSON format. It takes a very long time around 2-3 minutes to get the response on Android Device, where as on any other computer it works fine. Could anyone help me on this?
View 2 Replies View RelatedI've just recently started out with Android development, and have progressed to the point where I have written a very basic Hello World Jersey RESTful web service, and successfully called it from within my Android App.What I want to do now though, is send a new user record (just name and password for now) to a web service in JSON format.I can create my JSON in the Android app just fine, but I don't know how to get it into the HTTP Request in such a way that the corresponding web service that @Consumes JSON can get at it.
1) Create Android App User object
2) Turn that into JSON
3) Put it on the HTTP request
4) Call the web service
5) Web service retrieve JSON from request
6) Parse the JSON into server side User object and deal with as I see fit(Don't worry people, I'll be fine with this bit,
7) Profit! ;)
I have a WCF REST service built with C# and it returns an image as part of a CPU intensive operation. The client is running on Android (Java) By default, it will return a text JSON object that looks something like this:{"d",[9,0,77,12,11,...]}Those are they bytes of the image. Fine. However, all the solutions for decoding this JSON are intolerably slow. I've tried Gson, Jackson, and the built-in Android JSONObject class. I have no idea why they are so slow.As an alternative solution, I have my REST service return a GUID, and then that GUID can be used by the Android client to go to a regular URL that serves up the image as a regular binary stream, via an MVC controller. This works well, and it fast, and is pretty easy to handle on the Android side. However, it does feel like a bit of kludge and kind of a violation of the REST design principles.
View 4 Replies View RelatedI just would like to ask if anyone have encountered this strange behavior with other phone models or specifically HTC Tattoo wherein I have this service running for almost 5 hrs then after sometime the system kills the service. The phone does not restart actually nor any other 3rd party applicaton running in the background. Its only the service I have is running. I was wondering what were the causes that would force to close my service. Another strange thing is that before the service was closed I still can see all the logs in the logcat but after I saw that the service was closed I don't see any log information already seems like the phone was totally disconnected from my eclipse.

View 4 Replies View RelatedSo I'm working on a service that will handle requests to send data to a socket.I've done socket programming in a service before, but only within the same application. I'd like this to just sit and do nothing until any application wants to give it data to send. That's all well and good.I have register an intent filter and the usual stuff and can process the data. But I want to process the data coming from different activities in different threads (subsequent calls from the same application will be computed on the same thread).Is there a way to get the calling package or app or whatever? I'd prefer not to require passing in an identifier as an extra to prevent spoofing. (It's not a serious security concern, it's just each application needs its data processed in the order that it's received.)

Why it is happening?And also, If I use my public IP, I can't access web service. But If I put the same code in another machine, and call that web service using the IP address of that machine, It works fine.

I'm pretty sure that android services are going to be the end of me.I have almost no hair left after the last few days.At first I was having a heck of a time getting the service to bind on an onclick of a button, got that straightened out from help here yesterday. Now I actually want the service to bind in the onCreate() method of the activity. That part is no problem, works as intended.My service is actually a socket service to connect TCP sockets to a socket server that I wrote.If I put the call to the method from the bound service mBoundService.StartSocketServer() inside a button click, bingo, works great. But I need this to fire up immediately when the activity loads, so directly under my bindService() call within my onCreate() method of the activity.When I place the call to start the socket inside my onCreate() I get a force-close.
This method (StartSocketServer()) spawns a new thread then opens the socket on that thread to my remote machine.I'm guessing that the problem lies with the new thread generation before the activity fully loads not sure.LogCat is fairly cryptic here. It does say something about thread attach failed, then shows an uncaught handler exception that has "Caused by: java.lang.NullPointerException" within it.Again, if I put this call to the method inside a button click, I"m in business, if it's in the onCreate() it fails. Is there some way inside an activity (presuming that my assumption is correct that it needs to fully load before spawning a new thread) to call the StartSocketServer() after it's loaded: ala body.onLoad() in html?
I have a .Net Web Service which returns a single integer value. When i call upon it from my application, no value is returned. Nothing at all really happens. I set up breakpoints and watched it's progress and it seems the problem is coming from when i get to this line:androidHttpTransport.call(SOAP_ACTION, envelope);
I have a hunch that my URL string is the problem. I've tried replacing the "localhost" in my URL string with my local and network ip with no luck. Whenever i replace the localhost with the ip in my browser i get Server Cannot Access or Unable to Connect pages. Does anyone know a solution to this problem?
A service is setup by an activity with startService(service_intent). This service is meant to run 24 hours a day. After some amount of time, 5 or 6 hours sometimes but its not predictable, the service is killed.In the database log, the destroyed message does not show up and the notification #1 is not cancelled. Android makes no attempt to restart the service. The database log will show the startup of the replacement service if I trigger it by visiting the activity. What can I do to keep this service running or at least get it restarted by android automatically?

Is there a way that a Service can report back to the calling activity when the Service has reached a particular stage of processing? Consider a music player activity that initiates the actual music playing in the background as an Android Service. I want to detect and inform the Activity when the Service has reached the Mediaplayer's onPrepared. Is there a way that the Service can tell the calling Activity when the MediaPlayer's onPrepared is called, to let the Activity know that the audio is prepared and ready to play?I am basically looking to see if there is work around, rather than having a thread in the activity, pinging constantly to check if the Service has reached onPrepared.

View 3 Replies View Relatedfew weeks ago I encountered a problem. My Android SDK 1.5 emulator became very slow and CPU consuming. This happened earlier, but was irregular just removing AVDs usually helped. Few weeks ago I installed Android SDK 1.6, tried to move my dev environment there and noticed that emulator runs very slowly. I rolled back to 1.5 and noticed that the same problem is there. What's going on: - emulator startup is pretty slow; - sometimes emulator hangs on startup; - sometimes after startup is complete I see Force close/Wait dialog for some Android applications/services (Alarm clock, messaging) - applications inside the emulator run MUCH slower than they ran before, I see delays in response even in launcher, when I just switching between icons with arrow keys (at this time CPU usage according to the task manager is from 35 to 50%, i.e. one core is completely busy). - now, when I'm typing this message, emulator (clean, newly created AVD, I haven't installed nothing there, just out of the box) occupied 50% of my CPU (and 140MB of RAM). Hardware: Intel Core2Duo T7500 (2.2GHz) + 2GB RAM. OS: Vista I don't have any problems with 1.6 on Linux (Kubuntu 7.10), emulator starts quickly, responds in a flash, and seldom consumes more than 20% of CPU time (usually in case my application is working with DB).
View 2 Replies View RelatedFor instance, we are in SomeActivity and the activity has a button that invokes moving files from one dir to another (let's call it job).On Android things change. I know there's the AsyncTask that is probably provided to solve my case. There's even a good example of how it should be used. But since there's no guarantee of how long an Activity instance will live the AsyncTask should be cancelled on onSaveInstanceState (and restarted on onRestoreInstanceState). This means using AsyncTask there's no guarantee we are able to fully fulfill the job once started. In some cases as sending an http post request for creating a user I would not want to get in "user already exists for this login" trouble on reruning the AsyncTask. This is possible since the AsyncTask can be interrupted while the request is already sent (and the server actually is doing its job - creating a new user), but the AsyncTask is canceled before we got the response.

View 3 Replies View RelatedI need to implement a JNI which render image with 3-party native function. This function call is time consuming, it cost about 1s to return. I found during that time, even if I call the JNI within another Java thread, the whole Dalvik VM is blocked. UI is frozen. I guess that's because Dalvik doesn't implement Java thread with a native thread, so any time consuming native function call will block the whole VM. I wonder how to solve this problem. My best guess is I should create a pthread in JNI to call that 3-party native function. But I don't know how to implement this kind of JNI.
