I am trying to do the program to monitor Missed calls. I start a service in Activity, and use BroadcastReceiver in service to monitor Missed calls. How to continue monitor Missed calls after Activity is destroyed?
Now I want to a progress of background to realize this. Thanks in advice.
This is a very good tutorial about service in android:
http://www.vogella.com/articles/AndroidServices/article.html
According to this , your Service will keep working in background until it is stopped explicitly, even if your app is in background or is closed.
Service always keeps running in the background unless you explicitly stop it... Here is a good tutorial that should get you started:

I have a service in my application but this service stop working after time and i want to keep the service keep working without stopping and for that i try to start the same service from onDestroy method when it dieing but its not work even the written log not appear ,so it is possible to call the service from itself and if it not may i create another service who do the same work and they call each other when one of them stopped, so when in onDestory i cant call it so how to call it?, wish that someone can help me with this situation thnx on advance
You should not try to start the service again yourself. Better return START_STICKY or START_REDELIVER_INTENT from onStartCommand() and the system will do it for you when it has enough resources.
See the following link where there is also an example.
http://developer.android.com/guide/components/services.html
I have a thread (Updater) inside a service (RefreshTasks) that check if there are some updates on the server. Then I have 4 activities that use those data.
But I have a problem in managing this service...
I would like to keep the service active along the whole application, even if the screen goes off. What is the correct practice to manage a service like this? In this moment I start and stop the service every onResume and onPause method of all activities... but this implies that the service will stop when the screen goes off.
Any suggestion?
Thanks AL.
The Service instance continues to run also when your app is paused.
I suggest you to look also this service provided by Google, which is a good solution for push notification in communication between the device and your service:
https://developers.google.com/android/c2dm/
And this is a good tutorial to start with:

I have an application which contain an activity and a service. The activity runs the service. When I start something big like a game (for example AngryBirds), I get a message "Low memory: no more services" in the LogCat and my service shutdown. But if I run music on background it works well and continue working...
So I have 2 questions:
I guess the android killing my process, because it is contain my
activity. Am I right?
How can I implement immortal service like the player service?
Thanks
You should only do this when the user knows that the service is running all the time and has profit of this. If so, check the startForeground method on the following link:
http://developer.android.com/reference/android/app/Service.html
If not, you should improve your architecture. Most service don't need to run all the time and it might be useful to persist the data of your service.
I created an Activity and started a service in that activity.The service should run in the background even if we make the application to force close.Please help me to solve this problem.
Services run on the same proccess of its application. For this, they should die if its application is force closed.
Maybe you should think about using different threads:
Processes and Threads
When app gets force close then service gets destroyed.
Check out below link, which shows a Return value from onstartCommand func.
http://developer.android.com/reference/android/app/Service.html#START_STICKY
By this system restarts service.
Check this also.

Hello Android Gurus
For API Level 7 and Above-->
I am badly struck trying to figure out a solution for the following problem:
I have an activity which i would use to Kick start an Service. This is an infinite loop service which can run forever. I would like to disconnect the Service from Activity and at a later point of time i will call the activity again which should tell me the current state of Service and i can Stop the service.
Is something like this possible. Right now my Service is Sticky and i am not able to Close the activity as Service is running for ever and i am also not able to Stop the service from activity.
Code samples would be of great help!!! Thanks in advance...
Multiple questions:
You can disconnect/reconnect from the Service using bind. Unfortunately the best advice to give there is to carefully read the documentation for Service at http://developer.android.com/reference/android/app/Service.html: look carefully at the Local Service example, as it demonstrates what you need to do to bind/unbind to a sticky service.
To stop it, once you've bound you can call stopSelf.
Start the service non sticky from the Activity.
In the service control the flow logically, say calling onStart() to keep it running.
Call onDestroy() when you have to stop.
