Android :: Service Running After Pressing Home Key
Nov 24, 2010
I have an Android service, created in OnCreate of first Activity of the application using StartService(). I need this service to be running throughout the life span of the application ie, all the activities in the application. But the service should not consume the resources after user pressed Home key or Back button. Is there any elegant way to do that other than stopping the service in onPause() method of all the activities?

I created and binded a service in an activity and I would like to know how I can avoiding the android application to stop when I press the back button. When the back button is pressed the onDestroy method is called and I unbinded the service in this method. I try to prevent it by taking care of the back button event and manually call for onStop() method but it always called onDestroy after, why?

I've recently been getting user complaints that when they leave my app by pressing the 'Home' key, my app continues to play sounds like it is supposed to, but when they go back to the app, a new one opens, but the old one is still running in the background. I have noticed this sometimes myself too, but only recently (my app has been on the market for a while now). I've done some testing myself and noticed that when a new instance of the app is opened after pressing 'Home' then starting the app again, pressing the 'back' key will go back to the original instance of the app that was opened. This means that the original instance of the app was not killed, but a new one was just opened over it. Has anyone else experience something like this?

I am making an Android game with an Activity called Game, a SurfaceView called GameView and a Thread called GameThread. The Game's onCreate(), I make a new GameView, which makes a new GameThread, where all the game logic and canvas drawing is carried out. However, I'm having some lifecycle difficulties. When I press back and restart it, it works fine, but when I press home and restart it, all I see is a blank screen. Here are the GameView's onSurfaceCreated() and onSurfaceDestroyed(): @Override public void surfaceCreated(SurfaceHolder holder) {
mThread.mRunning = true;
mThread.mWidth = getWidth();
if(mThread.mWidth > 550) mThread.mWidth = 550;
mThread.mHeight = getHeight();
try {
mThread.start();
} catch(IllegalThreadStateException e).......

Whenever I press the home button when Im in the root task of my application and when I click on the icon of my app again the state of my task (activity) is retained, but when i press the back button on the emulator and when I open my application its state is not retained. I want the state to be retained in both the scenarios.
In the mnifest I have given the below entries,
android:alwaysRetainTaskState="true" for the root activity
android:launchMode="singleTask" for the application

This is difficult for me to diagnose because the Log doesn't provide the offending code line that indicates what caused it.Running the app in the Emulator seems to work OK until I press Home or Back from the Main Activity. Using Back between the activities in the program seems to work OK, it only fails at the Main. I don't have the app finished yet so I haven't loaded it to a device yet.The Log says there was a null pointer exception so I would like to find why.The log points to the android routines (and I don't appear to have the source for those routines in the emulator-most but not all and these are refering to those I can't access). The log gives up at one point and says "11 more".It would be nice to see the remaining 11 in the hopes that one of them points to the line in my code that caused the offense.I'm looking for ideas on ways to find the error and hopefully cure it.

Motorola Droid 2.2 Froyo rooted Bugless Beast 0.5. Randomly (Maybe 2/5) when I press home from the browser, an application, ending a call, etc. All of my icons will disappear for 4-5 seconds. Please tell me if you know of a fix or anything about this problem, I've seen other topics about this but no solutions that worked.

I am tonight at a party and a good friend asked to use my phone for the music I've got on it (16g class 4 SDHC updated twice a week ). I after a long conversation of "If you break my sh-- I will have to kick someone's butt." I gave it to her and she plugged it in. Long story short, somehow it was knocked off the table and into a puddle of what I will, for lack of a better word, call fluid. I assume it was beer but still am unsure. Now, I've dried it out using the "Rice Trick" and leaving it on top of the heater vent, put the battery back in turned it back on and the screen was totally un-responsive. I tried a battery pull to see if that would fix it, but to no avail, it was still un-responsive. I then tried the factory reset (Home+Back+Tap Power>Clear>Reset). Now when the phone boots up and everything loads, Navigator will load and start up all on it's own and when I press the Home button Navigator starts up again. Tried the factory Reset again and the same problem. I was going to just re load the 2.27.651.5 from sprint (I never deleted it from my PC when it first dropped) but when I connected my Hero to my PC it wouldn't detect the Hero, It would charge, but not Mount/Sync/Share.

One thing that's bothering me about SH... I don't use Beautiful Home anymore. In fact, I've removed all beautiful widgets from all my home screens and home screen replacement apps. Yet for some reason I get the weather thing in my status bar as if I had Beautiful Home running. Which means it's somehow being run without being told to. And it only does this with Sweeter Home.

How do some android app make their service restart even if killed from task manager? A good example is Lookout security app. What I guess is that it has registered for all common events that are announced like app installed unistalled, interenet available ,etc.Is this a way to keep your service running ?Another solution I found was to make 2 services monitoring each other, so if one gets killed restart another.Which one would be a proper approach? Is there any way in android to start booting automatically(if device is switched off) once connected to power source? I have never heard this on mobile platform.This is possible for PC through bios feature. Can it be done on android?

I 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()"?

I want the application to run in background. This application should run continuously and should never get killed. Will running application as Service solve this issue? The application should get started automatically on start up. I don't need any GUI for this application. The main issue is Service getting Killed. Does service get killed ? and in what conditions will that happen?

I have an app that has a service with it. This service is started the first time you open the app is is suppose to run continuously in the background every two minutes. It seems that at some point though the service stops running or alarmManager stops scheduling/doing what is requested of it. Here is a breakdown of my code flow.
User opens the app,. Service is started, Inside the service I cancel any alarms that might be for this app then create a new one set for two minutes out, Once the alarm is set I call a GPS location check to get lat/lon, I then call up a .net web service to do some stuff with the lat/lon, Once text is returned I check that text for certain Items, If a certain item is found I send a broadcast out to a receiver that then creates a wakelock, starts a new intent to open an activity of my app then sounds an alarm, Right after I broadcast I call stopSelf() as well as calling stopSelf() if the text did not contain certain Items, I call finish() on the new activity I started if we go that far once the Active screen of my app is closed.
The reason I think something is dieing out here is because after some point in time usually once I wake up in the morning and check the phone I no longer see my GPS icon on my droid checking every two minutes.

I have an application that starts on boot using a broadcast receiver, also I have an activity and a process, because the service must run always on the background I am starting the service on it's own process using the android:process manifest tag.The ui is only for presentational needs and I would like the user to be able to run the service even if the activity is not active.when I press the back button or the home button the activity's on destroy method is called and the service although seems its running (it appears on the task manager) its not behaving as supposed, it should connect to the net and send some data but every X time using an timer task but the task never fires so the data are never send.

Is there a way I can test if there are any other activities in my app still alive? I am looking to stop a service in an onDestroy method, but only want to do this if there are no other activities from my app still alive on the stack.
I have the call stop the service in the main activity's onDestroy() method. This works perfect EXCEPT that if a user launches my app, then launches a few activities in my app, then hits the home screen and RELAUNCHES my app, they will subvert my order and the main activity will now be above other activities of my app. From this state, if they hit the back button and 'back out' of my home screen they will trigger the onDestroy() method and kill the service even though there are other activities open on the stack. I want to avoid this by stopping the service ONLY if I am sure there are no other activities of mine open on the stack.

I'm trying to create a program with a service that runs every 10 seconds, puts the camera preview, taking a picture and then leaving the user to continue his work (closing down). Currently I have two problems:
1. After I'm taking the picture, the preview still there. There's no function like close() to return to the previous activity. How can I return to the previous activity?
2. I'm trying to run the above described activity from the run() function (from the timer class that execute the run() function every 10 seconds). When I do that, a runtime exception is raised. But when I start the above described activity from a button clicked (not from the timer) it works fine.

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?

Sorry for the newbie question, but does anyone know how I can check whether an IntentService is already running? I'm starting an IntentService from onCreate within a normal Activity, and that means that if the user minimises and maximises the application, it gets called twice. I'm wondering if I need to use something like the solution here http://bit.ly/du3VW5 or whether there's a simpler way.
