Usually, I putExtra inside an Intent to transfer stuff between Activities. But it seems like I can't do this with a Service? Bundle extras = getIntent().getExtras(); That doesn't work for a android Service. How do I send a string from an Activity to a Service then?

View 2 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 1 Replies View RelatedI am writing a widget on Android 1.6 that shows the minutes that a person has used on the current month.
The way I have it setup is by having a service that listens to the state of the phone and when the phone is picked up, it starts the timer and when the person hangs up, ends a timer. I would like to send this variable(long duration) over to my appWidgetProvider so I could update the edit text on it.

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.
I want to create an app that contains a Service S and an Activity A. The Service S is responsible for preprocessing, such as preparing the data shown on the UI of the Activity A, before the Activity A gets invoked.I want to be able to invoke the Service S from outside the package, say from another Android app's Activity class B, do the preprocessing, and then when the data is ready, invoke Activity A. What is the best way to share data between the Service S and Activity A?How can the external activity B communicate with the Service S to determine if it has completed with all its preprocessing, and the Activity A is ready to be invoked?

View 1 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);
View 4 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.
I am pretty new to this but I was told I could get good help here. A friend and myself are playing around with creating Android apps (using ADT)
Here is how we are trying to make the program: in activity, user sets threshold values for the X and Y axis on accelerometer. When user hits button "Start", startService is invoked and starts TiltService.
TiltService is designed to run in the background always on the phone without user interaction. TiltService constantly compares the threshold with the accelerometer values and will vibrate if they are off.
My problem is I can't seem to get the putExtra() data correctly. I have overridden the onStartCommand in my service but I get the message "unreachable code" when I save the getExtras() to a bundle.

I thought I understood the basic of how Intents could pass data, but I guess I don't. Is it obvious what I am missing?
I've a service that is receiving UDP data from the network. I want to push this data from the service to a UI activity.
One way to do it is using broadcast Intents. What is the performance overhead of sending broadcasts frequently from the service to the activities?
Are there any other alternatives for doing this?

View 1 Replies View RelatedI need to develop an application with downloads the data at the background and update about the progress in the front.
I guess this can be achieved using services and activity and passing data in between the. But, what I need to do is even if I hit back button and then start the activity again. It should check if the service is running or not. If service is not running it should start one else it should display the data from running service.
Something like music player where music is played by a service at a background and activity displays the information. Even on browsing through other activities of the application or hitting back, state of the music player is maintained.

View 14 Replies View RelatedI have a strange issue. I am using KSOAP2 to create a soap request to a .net webservice. I do this in a few other places and everything works fine. The webservice basically queries a data base and takes the values from the data reader and creates a string. This string is then returned. When I run the webservice on my local machine(Without using android) it works fine. When I run it from the webserver (still not android) it works fine. When I call it from my phone however the line: String hazards = (String)envelope.getResponse().toString () ; //Get response from .net Web service Simply is filled with anyType{}. Now if I go to the webservice and I manually type in the contents from the database to represent what the string concatenation should be it works perfectly. The line: String hazards = (String)envelope.getResponse().toString(); //Get response from .net Web service Now returns the string value i need. Does anyone have any idea why this is happening or know a better place to ask this question?

How can I pass a string from an activity to a layout?
I can pass arrays from an activity to a layout with the following activity code...
Is there a simpler way to just pass a single string instead of any array of strings, from an activity to a layout?
I want to pass a String like the input of a new activity, to let this one use the String some operations. The code I try is this..
And in the activity I try to recover it:
String textout = savedInstanceState.getString("contactcode");
In the onCreate part. I have seen that uris are normally used, but I don't know how to pass that String by using a URI.
