i have a question about Services in Android.I have a application with two Services A and B.Is it possible that Service A can stop Service B?I dont want to do it through a Activity, cause the Application will be in Background. If some special Event happen in Service A, then it should tell Service B to stop. How can i do that?

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.
View 1 Replies View RelatedI have an Android Service that is started by my application and does some things in a threadPool using Executors.newCachedThreadPool()
Once it has finished doing it's work I would like the service to stopSelf(), how can I get the service to determine when it is no longer needed (ie, there are no more Threads executing) so that it can shut itself down automatically?
How 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?
I 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.

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.
This all worked on froyo 2.2 on a samsung galaxy tab.
Here is the snippet from logcat when I do an 'adb install testService.apk:
Code:
D/AndroidRuntime(15251):
D/AndroidRuntime(15251): >>>>>> AndroidRuntime START com.android.internal.os.RuntimeInit <<<<<<
D/AndroidRuntime(15251): CheckJNI is OFF
D/AndroidRuntime(15251): Calling main entry com.android.commands.pm.Pm
I/ActivityManager( 153): Start proc com.android.defcontainer for service

I have a service running in the background.I have a background thread that gets a reference to the service from the application's main activity. But when the background thread calls a method in the service to display a toast, I get the "Looper not initialized exception".Why,if I have a valid, bound reference to a Service, does this still happen?

View 2 Replies View RelatedI am trying to run the sample soft keyboard included in the SDK. I am using the debugger, and the literature says that to use a breakpoint while debugging a SERVICE, I need to include:
android.os.Debug.waitForDebugger();
So here is the portion of the code I modified:
CODE:...........
I have put a couple of breakpoints, at the statements indicated by the comments.
This is what happens: the debugger first stops at the breakpoint1, for a few seconds. But then the service restarts. For the life of me I can't figure out what makes the service to restart.
My service works exactly the way i want as long as i use start and stop and communicate using intents. However my activity needs to change the state of my service as well as retrieving state information.So i thought it would be nice to broadcast some kind of state_changed event from my service and use a binder interface to pull information from the service or change the services state based on user input.This works fine too. The only problem is that my service gets killed when i unbind it just as the documentation says.Is there any way to keep the service alive but still get an interface to control it directly. My activity offers the user a way to stop the service and the service kills itself anyway after it's work is done but i don't want the service to stop every time the activity is destroyed.
View 3 Replies View RelatedI'm confused about whether I need to run my service in a separate process. What are the advantages / disadvantages of each?For reference I'm trying to create an App that uses a service to play [streaming] audio in the background. So which one is better for my use case?
View 1 Replies View Relatedwhat I'm trying to do here is implement something like a peer-to-peer client. Being that, it will start a client thread and a server thread.I know Services themselves run in the main GUI thread, so I'll have to start a couple of independent threads (or Asynctasks?) for each server and client. The only thing I'm not so sure about is if I'll better have 1 Service starting 2 threads, or maybe 2 services, each one of them starting their own thread.

I am developing an Android app which needs to poll a specific webpage in time intervals. I've got it to the point where it does indeed poll the page on a specific interval, and that interval is specified in a SharedPreference which can be changed by the user in the settings page of the app. But complications arise when network connectivity is flaky.For example, how do I ensure that the Service "wakes up" the network adapter and gives it ample time to connect before polling the page, in the case that the phone was sleeping to save power? This polling action can happen as little as once every 24 hours, so I don't want to miss one action just because the network was out (but turned on a few seconds, minutes, or even hours later).
Or there are times when the web service doesn't respond, or DNS doesn't respond, or what have you, and for any reason it doesn't get a response even though the phone is technically connected. What sort of rule do I put in place to make this retry later, so that I'm not retrying repeatedly when the user specifically turned off their internet but I'm retrying soon enough that if it was just a hiccup, the data can be received soon after the first try?Are there any examples for this type of situation? What is the logic to best handle this?
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.

View 7 Replies View RelatedI am creating a application whose only component is a service which keeps on running in background (basically a proxy server) but I am not able to find a way how to start that service. Application can not have any UI or user interaction so I am not using Activity.Broadcast receiver can listen to BOOT broadcast but how do I start service first time when it is installed and how can I keep it running?or is there a broadcast which I can listen after app is installed e.g. may be TIME_TICK but that has to be registered from activity i think.
View 4 Replies View RelatedI would like to know the best practices for running a Service every day at 4AM.The way I think I should be doing it is to create a new repeating alarm using AlarmManager and having it run the service at 4AM. Problem is, I'm not sure where to put the code to set the alarm.Do I do it in my main activity as one of the first tasks in the OnCreate method? Do I do some funky stuff with BroadcastReceivers and intents? What happens when a user updates my app? What happens when a user restarts?Any help with these questions would be much appreciated.Sample code would be helpful as well!

View 1 Replies View RelatedService Component is used to do some task which can be done without user interaction. But for that we have to run a thread in subclass of the Service. I think we can create a thread in Activity class itself then what is the use of Service component? Why don't we create another thread and write the non interacting code in this thread.
View 10 Replies View RelatedI am new to Java and Android.I would like to retrieve remote data and display it within my activity. To prevent tying up to UI, I understand that I can do this in another thread. (I thought I could just-as-well fetch this remote data from within a service, but that appears to tie up the UI thread also). So now I'm beginning to think I need to either run the logic from a new thread within a service, or run a service within a new thread. But which? I have found many examples online of running new threads or services, but I have yet to find an example of both at the same time.
View 7 Replies View RelatedAndroid has such concept as a Service. It makes sense for interprocess communication. But if I need this service from Activities running in the same process regular singleton seems to be more convenient. No need to register, to bind. Are there any benefits to use service in the same process?
View 17 Replies View RelatedI'm quite new to Android development. When is it a good idea to create an Android Service instead of just using a simple Singleton class?
Take, for example, the data layer downloading information feeds from the internet. Using a Service seems too much for some cases but sometimes I might need access to a Context so I'm a little unsure about how to design the app.
