android - Why does the background service stops while running? -

i have background service in android application.in thread listening recent tasks running frequently.my service overrides both oncreate() , onstartcommand() methods. when tried open applications gallery,camera etc..., service stopped.it calls oncreate() method , not ondestroy() or onstartcommand().i tried override onlowmemory() in service logs nothing.the application saved internally specifying

 android:installlocation="internalonly"   

in manifest file.

note: issue noticed on micromax a54 2.3.5.

why background service stops sometimes? there solution issue?

public class myservice extends service {      public myservice() {     }      @override     public int onstartcommand(intent intent, int flags, int startid) {         try {             if(intent != null){                 //......             }         } catch (throwable e) {         }         return start_sticky;     }      @override     public void ondestroy() {         super.ondestroy();     }      @override     public void oncreate() {         super.oncreate();         //......     }      @override     public ibinder onbind(intent intent) {         return null;     }   } 

and start service this

intent intent = new intent(getapplicationcontext(), myservice.class); getapplicationcontext().startservice(intent); 

android can stop service @ time reason. typical reason low memory (killing service give memory elsewhere), i've seen @ least few devices kill them every x hours regardless. there no way ensure run. best can have activities try start service (in case isn't running), write service can reload needed data, , set start_sticky if has enough memory framework restart later.
