android - 在 firebase jobdispatcher 中停止 JobService 内的预定作业

Question

我在我的应用程序中使用 firebase jobdispatcher，但我遇到了一个问题。我想在任务完成后停止工作。我尝试在 onStartJob() 方法中调用 selfStop()。但它的 onStopJob() 永远不会被调用。根据我的应用程序中的要求，我正在完成启动工作的 Activity 。那么谁能告诉我如何在 JobService 类中停止作业。

代码示例:

//使用 Google Play 驱动程序创建一个新的调度程序。

        FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(this));
        Job downtimeOverNotificationJob = dispatcher.newJobBuilder()
                .setService(AppJobService.class) // the JobService that will be called
                .setTag("my-unique-tag")        // uniquely identifies the job
                .setTrigger(Trigger.executionWindow(20,20))
                .build();
        dispatcher.mustSchedule(downtimeOverNotificationJob);



  @Override
    public boolean onStartJob(JobParameters job) {
        Toast.makeText(this, "Job started", Toast.LENGTH_SHORT).show();
        new Handler(Looper.getMainLooper()).postDelayed(() -> {
            //Do something after 10000ms
            stopSelf();

        }, 5000);
        return false; // Answers the question: "Is there still work going on?"
    }

    @Override
    public boolean onStopJob(JobParameters job) {
        Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
        // Vibrate for 500 milliseconds
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            v.vibrate(VibrationEffect.createOneShot(500,VibrationEffect.DEFAULT_AMPLITUDE));
        }else{
            //deprecated in API 26
            v.vibrate(500);
        }
        return false; // Answers the question: "Should this job be retried?"
    }

感谢任何帮助。

Need to call jobFinished(job, false) if you want to restart job manually and get onStartJob(JobParameters job) callback.

Example:

     @Override
        public boolean onStartJob(JobParameters job) {
            Toast.makeText(this, "Job started", Toast.LENGTH_SHORT).show();
            new Handler(Looper.getMainLooper()).postDelayed(() -> {
                //Do something after 10000ms
               jobFinished(job, false);

            }, 5000);
            return false; // Answers the question: "Is there still work going on?"
        }

        @Override
        public boolean onStopJob(JobParameters job) {
            Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
            // Vibrate for 500 milliseconds
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                v.vibrate(VibrationEffect.createOneShot(500,VibrationEffect.DEFAULT_AMPLITUDE));
            }else{
                //deprecated in API 26
                v.vibrate(500);
            }
            return false; // Answers the question: "Should this job be retried?"
        }
