如何每4小时启动一次服务

Question

我需要使用setPeriodic指令每4或5小时启动一次服务，但是每次更改setPeriodic指令的参数值时，它会每3分钟在max：/午餐一次。

我的代码：

        mScheduler = (JobScheduler) getSystemService(JOB_SCHEDULER_SERVICE);

        RadioGroup networkOptions = (RadioGroup) findViewById(R.id.networkOptions);

        int selectedNetworkID = networkOptions.getCheckedRadioButtonId();

        int selectedNetworkOption = JobInfo.NETWORK_TYPE_NONE;

        ComponentName serviceName = new ComponentName(getPackageName(),
                NotificationJobService.class.getName());
        JobInfo.Builder builder = new JobInfo.Builder(JOB_ID, serviceName)
                .setRequiredNetworkType(selectedNetworkOption);

        int seekBarInteger = mSeekBar.getProgress();
        boolean seekBarSet = seekBarInteger > 0;

        //Set the job parameters based on the periodic switch.

        builder.setPeriodic(1000*60*400);//3mins =240000//\1000*60*400
        //builder.setMinimumLatency(1000*60*10);
        //builder.setOverrideDeadline(1000*60*15);
        //Schedule the job and notify the user
        JobInfo myJobInfo = builder.build();
        mScheduler.schedule(myJobInfo);
        Toast.makeText(this, R.string.job_scheduled, Toast.LENGTH_SHORT).show();
    }


    /**
     * onClick method for cancelling all existing jobs
     */
    private void cancelJobs() {
        if (mScheduler != null){
            mScheduler.cancelAll();
            mScheduler = null;
            Toast.makeText(this, R.string.jobs_canceled, Toast.LENGTH_SHORT).show();
        }
    }
}
