如何使用 Firebase 作业调度程序定期启动任务

Question

我使用 Jobschuler 每 x 分钟发送一次通知(动态确定(，如下所示

ComponentName componentName = new ComponentName(context,ClsJobService.class);
JobInfo.Builder builder =  new JobInfo.Builder(0, componentName)
.setPeriodic(duration * 60 * 1000);  //setting in millisecond
JobScheduler jobScheduler =  (JobScheduler) context.getSystemService (Context.JOB_SCHEDULER_SERVICE);
jobScheduler.schedule(builder.build());

它的工作很好，它可以按时发送工作服务中定义的通知

现在我如何将其转换为Firebase作业调度程序，我确实喜欢这个

FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(context));
Job job = dispatcher.newJobBuilder()
.setService(ClsJobService.class)
.setTag("notification")        // uniquely identifies the job
.setTrigger(Trigger.executionWindow(0, duration * 60))
.setLifetime(Lifetime.FOREVER)
.setRetryStrategy(RetryStrategy.DEFAULT_EXPONENTIAL)
.setRecurring(true)
.build();

dispatcher.mustSchedule(job);

但我只在计划时发送一次通知，之后就不发送

我最好的猜测是你应该将setTrigger((更改为：

.setTrigger(Trigger.executionWindow(duration * 60, duration * 60))
