I just want to develop a service which listens to the database and it should invoke an activity as soon as there is a change. I tried to implement Contacts listener by registering Content Observer but couldn't see the expected result. Kept log in on Change() method, observed that it is not getting called, any clue that where it might went wrong.

is it possible to send data to external sources.. like a remote sql server or a remote website?example: make a pic with G1 and send it to a remote db server (via internet).is there somewhere an example of how to do it? thanks for the info.
View 2 Replies View RelatedI have built an application that listen to call state changes, and I want to notify a service when the call_state became IDLE.All the components I have are functional, I just need to notify (not start) a service for this.What's the correct practice, maybe using AIDL? Because, in a PhoneStateListener, I can't bind to a service. Do I have to start an activity for that?
View 2 Replies View RelatedI have a BroadcastReceiver that listens for the BOOT_COMPLETED, that part works I know because I disabled my phone listener and displayed a Toast within. That BroadcastReceiver is supposed to start a service, that also works. I run into Force Close issues when my service attempts to tell my TelephonyManager to listen. Any one have any ideas? Here is my code StartSeviceAtStartUp.java import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent;
View 3 Replies View RelatedI want to test parsing of data returned from server.I thought I might create several test XML files and then feed them to the sax parser which uses my custom data handler (as in the application that I test).But where should I put those test XMLs?I tried with [project_root] /res/xml, but then I get the error: android.content.res.Resources $NotFoundException: Resource ID #0x7f040000 type #0x1c is not valid at android.content. res. Resources. loadXml ResourceParser(Resources.java:1870)at android.content.res. Resources. getXml(Resources. java:779) Does that mean that the xml is invalid, or that android couldn't find the XML file?(I use the same XML that comes from the server - copied it from the firebug's net panel and pasted into the file).Can I somehow read that XML as a text file, since etContext(). getResources() .getXml (R.xml.test_response1) returns XmlResourceParser instead of String (which I'd prefer)?

View 1 Replies View RelatedI'm stuck on a tough architectural problem. I have a collection of web services that produce data that will populate UI components - Text Views, List Views, and so on. Each web service may take up to about 10 seconds to respond, or it might not respond at all. When I click a button in the UI that requires data from the web services I need to show a Progress Dialog until either the data arrives or it times out. I'm pretty sure that an Intent Service is the best way to wrap the web services. From the documents (http://developer.android.com/reference/ android/app/Intent Service.html) "This "work queue processor" pattern is commonly used to offload tasks from an application's main thread." Also "Note that unlike other application components, calls on to the IBinder interface returned here may not happen on the main thread of the process."
The UI needs to get data back (asynchronously) from the Intent Service, which means using AIDL, onBind, and all that. But from the documents (http://developer.android.com/guide/developing/tools/aidl.html) we have "By default, IPC calls are synchronous. If you know that an IPC service takes more than a few milliseconds to complete, you should not call it in the Activity/View thread, because it might hang the application (Android might display an "Application is Not Responding" dialog). Try to call them in a separate thread." Of course, that "separate thread" stuff in the AIDL docs in nonsense. If you spawn a separate thread in an Activity it will get blown up in On Destroy. But what do they mean by "By default"? Are there cases where the IPC can be asynchronous? Is that what is meant by the text in the Intent Service docs "may not happen on the main thread"? How does this work?
I have created an activity that calls a service. This service receive an XML feed and parse the info. Each time I get the info for a new station i want to send the details (Name,Id,Location all as string) back to my main activity so it can load it inside a list view. When I run my code inside the main activity it works. When I move it to a service I cant send the data back. This is what I have tried. After getting the current station info from I do this: submit Station(namer, loc, ids, dis, types); then: private void submit Station(String names, String loca, String idss, String diss, String typess){Intent intent = new Intent(NEW_STATION_LISTING); intent.putExtra("Station Name",names); intent.putExtra("Sid", loca); intent.putExtra("StationLoc", idss); intent.putExtra("Distance", diss); intent.putExtra("Types", typess);send Broadcast(intent);}
View 3 Replies View RelatedI have just started using services in Android and I have a made a simple service that is polling a server every 20 seconds. Now how can I get this data from my main activity (when it is active)? Alternatively the service could send it back do my main activity (but only if its active). I don't want to wake up my activity. I have read SDK examples of "Binding" but I can't find an example how to actually get something from the service. Just how to start and stop the Binding. From the example. If I have the "mBoundService" object in my activity how do I get my data from the service method called eg. "polling Data()"?

http://stackoverflow.com/questions/1198558/how-to-send-parameters-from-a-notification-click-to-an-activity. but still no luck has any body occurred with the same issue.
So I'm getting really confused on how to do this whole thing and I was hoping someone could break it down for me a little bit.I have a service that should always be running, and at certain times it needs to alert the user that a task is to be completed(probably through a notification bar icon). When the user accepts the task, the service needs to look into the local database, construct some non primitive objects, and give them to the activity that it just started.I have looked all over and gotten very confused as to a proper approach so I have a few questions to help me wrap my head around it.If an activity creates a local SQLite database can the service and activities of that application access that same database later?Does the service and activity need to be in the same or separate packages? I would think no but for some reason I remember seeing something about this elsewhere.
How would I do the data transmission from the service to the activity? I was thinking a content provider but it seems like there should be an easier way for the service to just hand off the data. Similar to an Intent but for non primitives.

View 1 Replies View RelatedIs it possible, with an IntentService, to send another intent to the IntentService from within the IntentService? For example, say my IntentService is processing an Intent which has it write a bunch of data to the database. During this time, several other Intents to write other data may [or may not] have been queued up in the IntentService. Suppose, after processing that Intent by writing the data to the application's database, I want to queue up another Intent to send that data via web service to "the cloud." Perhaps I want to queue this processing in another Intent because sending to the cloud is secondary. Is it possible? Would it cause any problems if the Intent being processed is the only Intent in the queue at the time the IntentService is trying to queue another Intent?
View 2 Replies View RelatedI am little confused with the use of intents used for sending data to activity from service. In my application I have to have startactivity from the service and have to pass data ,so that activity can utilize the data while launching.For this i have written the following code Intent intent = new Intent(Service.this,Activity.class); intent.putExtra("data", data); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.start Activity(); I assume that the data is passed to the activity and can be parsed on the oncreate function of the activity.Now the service running in the background has to pass data to the activity continously for UI updates.For this I have written the following codeIntent intent = new Intent(Service.this, Activity.class); intent.putExtra("Data", data); intent.setAction(Intent.ACTION_ATTACH_DATA); sendBroadcast(intent,null); (Do I need to broadcast the intent???) In activity I have done following things:- Implemented broadcast reciever:private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if (Intent.ACTION_ATTACH_DATA.equals(intent.getAction())) { Bundle extra = intent.getExtras(); float Data[] = extra.getFloatArray("Data"); update(Data);

I have a web service, .asmx that when consumed gives a response in the form:
<lData>
<name>...</name>
<posx>..</posx>
<posy>...</posy>
</lData>
I use Ksoap2 to consume the web service in Android, and I see the response as a string anyType {lData=anyType{name=....;posx=....;posy=....;};}
So, I get the right data from my web service, but i don't know how to parse it correctly.
I want to find a way to iterate through the different nodes.
I have tried to use a SAXParser, but can't seem to understand what I should use instead of the url. In the tutotirals I have followed the link to a xml-file on a url, but my url is only part "finished" since i need to consume the web service first. code...
Is this above something I should use, but have another openStream?

View 3 Replies View RelatedI am a bit new to Android. What I need to do is send data back and forth between an activity and a service locally. The information sent is sensitive and must not be able to be picked up by other apps. This excludes using broadcast and the onBind() function if I understand things correctly? So the activity needs to send some string parameters to the service. Also it somehow needs to tell the service which activity started it so the service can reply to the correct class since many different activities will use this service.
Once the service has fetched the information via a http request it is suppose to send that data (just a long string which will later be parsed) back to the activity that started it. How do I go about doing this? Using static variables/functions is not an option since again many actives will be using this service. Sure it would be possible to use a static array to hold the classes but that just seems ugly. It's only possible to send simple variables (not objects) via the intent? There must be a better way to do this.
