Jun 3, 2010I'm having trouble getting my widget to stop hogging so many resources.I setRepeating on the AlarmManager to update. When the widget is deleted (onDisabled()), I call .cancel() on the service, but the service still shows up in the android "running processes" making me believe I'm doing something wrong.Also, should I be scheduling my updates in the onEnabled() or the onUpdate()? onUpdate doesn't seem to work on anything other than the first widget.

Android :: Getting And Stopping Single Running Service?
Sep 14, 2010How can I identify and stop single running services? More specifically, once I got the running services on a List as in a chunk of code like:
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE); List<RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);
Is there any method to stop a single service, i.e to identify one and then stop it?
Android :: Stopping And Starting Service Based On Application State
Oct 28, 2010I have a Service which tracks the location of the user. Currently, the Service boots when the application starts and stops when the application terminates. Unfortunately, if users keep the application in the background, the Service never stops and drains battery.
I would like the Service to stop when my application is not in the foreground. I was hoping the Application class would let me Override onPause and onResume handlers, but it does not have them.
Android : Back Button Not Stopping Activity
Feb 28, 2009In my game, I've got one activity starting another activity via an intent. When the user is finished with the second activity, they quit it using the back button. However, I have a problem: when this happens, the second activity is still running, even if it's quit with the back button.
My second activity will eventually give a "game over" message using a pop up window if there is no user input for a period of time. Problem is, when I back out of the second activity (where the game is happening) the "game over" message still appears eventually. This is how I know the second activity is still running. It even displays a "game over" message if my entire app is quit (on the Android OS).
How do I stop an activity completely when the user presses the back button?
General :: Simple Service Force Stopping Package?

I am having issues with a simple service not running correctly. The logcat shows some force stopping on the installed apk. Also the broadcast receiver should listen to android.intent.action.ACTION_POWER_CONNECTED but it is not.

Mar 17, 2010I am developing an android game right now, and it requires very precise timing and synchronization. That said, it is essential that there is no lag during the game. However I sometimes get lag spikes in the game, and I know its not the GC because I have run the ddms tool, and eliminated all the GC calls. However, I do see alot of background services popping up in my ddms logcat. Is there anyway to pause all services when my game is running?

Android :: How Does A Service Communicate With Activity?
Feb 17, 2010Suppose I have an Activity that's a list. It calls a Service when this Activity starts.The Service will do background stuff download, parse, and fill the list.My question is this: How can the Service communicate with the Activity?How can I call a method in the Activity, from the Service? (I'm new to OOP)
View 2 Replies View RelatedAndroid :: Using Thread In Activity Or In Service?
Jun 12, 2010In Virgil Dobjanschi's talk, "Developing Android REST client applications" (link here), he said a few things that took me by surprise. Including:
Don't run http queries in threads spawned by your activities. Instead, communicate with a service to do them, and store the information in a ContentProvider.
Use a ContentObserver to be notified of changes.
Always perform long running tasks in a Service, never in your Activity.
Stop your Service when you're done with it.
I understand that he was talking about a REST API, but I'm trying to make it fit with some other ideas I've had for apps. One of APIs I've been using uses long-polling for their chat interface. There is a loop http queries, most of which will time out. This means that, as long as the app hasn't been killed by the OS, or the user hasn't specifically turned off the chat feature, I'll never be done with the Service, and it will stay open forever. This seems less than optimal.
Long question short:
For a chat application that uses long polling to simulate push and immediate response, is it still best practice to use a Service to perform the HTTP queries, and store the information in a ContentProvider?
Android :: Service Callback To Activity
Jan 13, 2010Our application will expose a Service that can be called by Activities in other people's applications.In many cases, the parent applications calling Activity may be paused before our Service completes. I am looking for the best way for a Service to communicate back to the calling Activity that may have been paused.These are the known options:
(1) Require calling Activities to have a registerReceiver() with a custom action and broadcast to that from our Service. The only way to secure this registerReceiver() is with a signature-based permission.As our Service communicates with any number of unknown 3rd party apps,we can't sign our Service's parent app with all these unknown certificates. These apps would therefore be exposing an unsecured registerReceiver() on their Activity. Would ideally like to avoid requiring this.
(2) Create a PendingIntent to send results back to the activity and give it to our Service. Our Service would send data to calling Activity's onActivityResult(). Each time the result is delivered, the calling Activity will go through onPause() and onResume() but this should be OK.
(3) The calling Activities could create a Handler. The Activity would then create a Messenger pointing to that Handler and send it to our service. Our Service can then use the Messenger to deliver our message back to the calling Activity.

Android :: Start Service Without Using Any Activity
Oct 16, 2009My application has a background process which continuously waits on a socket for receiving messages and it should be started only once and at the time of application starting.Thus i want to do that background job in a service.
The service should not be started from the activity ,it should be started at the application starting.
How can i define the service,which will be started at the time of application starting?
If at all the service is started from activity.The activity can be destroyed and restarted.when this happens the service also be restarted .

View 4 Replies View RelatedAndroid :: Binding Service To Activity
Dec 16, 2009I am working on an android application, where the activity binds to a local service to perform certain tasks.Now I am binding the service in the OnCreate method of the Activity, after which the activity has to use the service object to invoke the functionality defined in the servicein the OnStart method. The problem here is that once a call "bindservice" has been made, we might not get the serviceobject immediately, so my service object would be null till that time. So i cannot invoke the service functions.So is there a way to determine in the activity that the service has been bound and the service object is valid and could be used now. For reference i'm attaching a code snippet for the same.

View 2 Replies View RelatedAndroid :: Service Gets Killed - Due To Activity?
Jun 10, 2010I have a service running in the background. It starts on device boot. Also, I have one activity (that appears in the task launcher) in which I have provided buttons to start and stop the service.
Now, I install the application on the phone and I start the service using this activity (and not on-device boot). As expected the service starts and starts doing its designated task. I no-longer need the activity. So it goes out of sight and may not be required for a long time now.
My question is, now, if the android platform kills this activity, will it kill my service too ? (This is because I see that after few hours, my service is not running anymore.). If this is true, then will the service continue running longer if the service was started on device boot.
