I've developed an android application with a service that runs in the background
the service is called like that
startService(new Intent(getApplicationContext(),myService.class));
but when I remove the app from the recent apps, the service stops and it crashes if I test it..
is there a way to prevent the service from being destroyed when swiping the app from the recent apps?
thank you
You can register a service to run on a repeating cycle using AlarmManager
http://developer.android.com/reference/android/app/AlarmManager.html
The service will run even if the application is not running.

When I used foreground service then when I kill the application then foreground service is automatically killed but I want to alive foreground service when the application is killed. this issue appeared in android 10 and android 11. how to solve this issue.
You can't do that as you should not be able to keep alive a foreground service after the application is killed.
You should only use a foreground service when your app needs to perform a task that is noticeable by the user even when they're not directly interacting with the app. If the action is of low enough importance that you want to use a minimum-priority notification, create a background task instead.
If you what to have some background service working, that will be possible.
You can find some useful information here :
https://developer.android.com/guide/components/foreground-services
https://developer.android.com/training/run-background-service/create-service
It should not get killed. When starting foreground service you need to create notification too. You have done that, right?
If you done everything right there is possibility that you have xiaomi phone. Xiaomi deletes everything when app killed. You need to add specific intent protection...
Want to run a service in back ground when SMS or call received then background service call the flash on and off. Application works on marshmallow and low version. But not work on Oreo 8.0 and Pie 9.0. Due to Background service application crash after 10 second when application open.
Android.app.RemoteServiceException: Context.startForegroundService()
did not then call Service.startForeground()
How we fix this issue?
You have to call "Service.startForeground()" within few seconds after called "startForegroundService()" or the Service will be killed by Android.

I have been reading Android docs and I feel I am bit lost and confused.
What is the type of service I need to use in Android, so that I can keep running my code even when the app is paused or minimized for prolonged period.
I am not interested in running the service if the app is closed. I want to run small piece of code that will run when app is in foreground or background, but not killed.
You can use a bound Service. The Service will stop after all the bound clients disconnect. Your Activity binds to the Service and when your Activity is killed or finished, you unbind and the Service stops. If Android kills off the Activity, the bound connection is also shut down and your Service will stop.
I am working on an android application that uses phonegap/cordova. This app uses a javascript to fetch content from the server from time to time and issues a systemtray alert if there is new content.
The problem I was facing was that the app would eventually just quit when android was short on memory or whatsoever.
So I added a service to my manifest (everybody says a service would solve the problem).
<service android:name="UpdateService" />
Verywell, but just having this service there does nothing (obviously). So how do I make my service trigger the main application to keep running?
ADDITION:
I also managed to start the service in my main application
Try registering a PendingIntent with the AlarmManager that will check to make sure your application is running every n milliseconds. If it isn't running have the service start your application again.
Use some code like this to start your application:
Intent serviceIntent = new Intent("com.myapp.LaunchActivity");
startService(serviceIntent);
Replace com.myapp.LaunchActivity with your package name and LaunchActivity.
I always used Android 2.2 for my Apps. But currently I upgraded to Android 2.3.X Gingerbread. So if I start my App and go back to the android "desktop", the app is kill by 3-4 Minutes.
I think it will be killed after some minutes inactivity, but I need to run it in background to read some mobile status.
How can I set my App as a "Background" App, so that Android will not longer kill it?
Thanks for Help...

To run an application in the background it must be of type "Service". You have to register a service and it will run in your device forever. For more info, Android Services
