Notify the Service if the Activity is Down

Question

Sometimes my app crashes for some reason and I have no control over it. I want to let the service know when the app crashes and do some other process.

Is it possible to do that?
By the way, starting from Lollipop, getRunningTasks is deprecated.

Thanks.

when app crashes, that I assume means your app is killed, in that case Android system will kill all it's components like Activity, and Service. So it means Service itself is killed. This don't leave any scope to `notify` anything to it — AADProgramming, Jun 25 '16 at 19:48

You can try to catch exception in application and then start your service. Check this answer

for a big App, you can not add try and catch in every activity – Mike Yang Jun 24 '16 at 03:48
Check carefully. You do not add it in activity. You add it in application class. – thealeksandr Jun 24 '16 at 03:51

You need to debug the exact reason for crash, but in General, if you have a Service running, then Android will notice that you have a service running and not kill it so readily. However, it is still possible that Android will kill your service process if it isn't "in use".

I want to let the service know when the app crashes and do some other process.

Assuming App crashes here means your app's process is killed by Android system, and in such an event, Service will stop running when system kill your application. Basically When your application is killed by the system, all components of it are killed (activities, services, etc.).

Hence, this situation don't leave any scope to notify anything to your app's service as it is already gone with app crash.
