[Q] Restart service after kill

Rick Clephas · Aug 15, 2014

Hi I want to start my service after it is killed by the user or the system.
I thought about creating a second app and monitor if the service is running and if not then start it.
The problem I have with that is
- I need two apps
- It drains more battery

I hope you can help me find the best solution for my problem

Yeah, I think if you override the onDestroy method on your service class, and then you can send a broadcast from there.
In your broadcast receiver you can start the service again.

Though i have never tried it myself, i think this should work.
Tell me how it goes

Happy coding!! :thumbup:

I thought about that too but unfortunately when the app is stopped by the user the onDestroy methode is not called...

If yu are using android version less than 4.4.2 then returning start sticky should do it

That is only if the system stops the service not if the user does....

I believe there is no such way... otherwise android would be very insecure for malware that just does this

. You can only restart your service once the user restarts your activity, there should not be another way (and START_STICKY for the system of course). And please don't do two apps which listen for each other, if the user willingly kills your service they usually have a reason and expect that your app is not working right until they restart it.

I have heard that a lot but does that mean that all the security apps available on the play store can be killed by the user? :what:

Sure, why not? I could uninstall my firewall on my PC if I wasn't using Ubuntu and thus don't really need one

Well that is a pitty. I really thought I had seen an app that could do that...

Look this app says it can't be killed by task managers https://play.google.com/store/apps/details?id=com.domobile.applock

Just an idea, it might be possible when your app is a Device Admin with the APIs that you get with that. Though you have to read it yourself, I have no clue about how it works.

Thanks I will look at that. Most people have my app as Device Admin because that way it can't be uninstalled

Well I found the solution.
When device admin is enabled the app can't be force-stopped or uninstalled. Then the user can only stop the service and then the onDestroy methode is called so then I can restart the service again. Tanks guys :thumbup:
