android - Job Service is destroying after some -

i have implemented jobservice in application don't know reasons stopping suddenly, , changing job time dynamically based on req.

here code

i calling startservice(context context) when interval changes

public class gcmlocationservice extends jobservice {     @override     public boolean onstartjob(jobparameters job) {              sendlocationtoserver();          return false;     }      @override     public boolean onstopjob(jobparameters job) {         return false;     }      public static void startservice(context context) {         // create new dispatcher using google play driver.         integer locationinterval = integer.parseint(sessionmanager.getinstance(context).getpreflocationinterval());         int min = 10;         int max = 10;         if (locationinterval > 2) {             max = locationinterval * 60;             min = (locationinterval - 1) * 60;         }          clog.e("gcmintentservice taskservice", "111 locationinterval------->" + sessionmanager.getinstance(context).getpreflocationinterval());         firebasejobdispatcher dispatcher = new firebasejobdispatcher(new googleplaydriver(context));         job job = dispatcher.newjobbuilder()                 .setservice(gcmlocationservice.class)                 // uniquely identifies job                 .settag(myapplication.gcm_location_repeat_tag)                 // one-off job                 .setrecurring(true)                 // don't persist past device reboot                 .setlifetime(lifetime.until_next_boot)                 // start between 0 , 60 seconds                 .settrigger(trigger.executionwindow(min, max))                 // don't overwrite existing job same tag                 .setreplacecurrent(true)                 // retry exponential backoff                 .setretrystrategy(retrystrategy.default_exponential)                 // constraints need satisfied job run                 .setconstraints()                 .build();         dispatcher.newretrystrategy(retrystrategy.retry_policy_linear, 60, 301);         dispatcher.schedule(job);         clog.d("location-- s>", "222 schedule job");     }
