问题
I am developing a task manager application..
In that app, I display to the user a list of running apps and kill button beside each app. When user presses kill button the corresponding activity will be killed and i used
activitymanager.killbackgroundprocesses(packageName)
I created another application called service notification where user can start and stop a service by clicking on button "start service" and button "stop service" respectively.. Then before running my task manager app, i started the service from service notification app. So this activity was displayed in my task manager app.
But when i kill that activity, it disappears from the list and then appears again because the service is restarting..How do I kill the sevice then?
I used startService and onCreate for starting service and showing some notification and stopService and onDestroy for stopping service...

I finally found an answer to my question...
After using
activitymanager.killbackgroundprocesses(packageName) ,
we have to check if there are any services running under that package name or process name.
Then we have to use
stopService(new Intent().setComponent(serviceInfos.get(i).service))
But it would return an error because android does not allow us to stop another service
So I used these two lines in the manifest and then ran my app in the build machine
coreApp="true"
android:sharedUserId="android.uid.system"
These two lines are there in the android settings manifest file, which allows settings to stop service if the user wants.
So the activity got killed along with the service... :)
And remember this worked only on the build machine....

Try To Use this permission in your android Manifest File.
<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />
and Look at this link it may be helpfull... http://developer.android.com/reference/android/content/Context.html#startService%28android.content.Intent%29
and this: Start a service on onClick
