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（动态确定）发送通知，就像这样

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());

它工作得很好，它会按 JobService 中定义的时间发送通知

现在如何将其转换为 firebase 作业调度程序，我确实喜欢这样

 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);

但我只在安排时发送一次通知，之后不再发送通知

我最好的猜测是您应该将 setTrigger() 更改为：

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