Question

我希望我的本机无头JS在后台运行，每30秒执行一次作业。当符合条件时，我想在Android手机上收到通知提醒。手机打do睡之前，一切正常。警报作业设法按时触发通知消息，就像我在警报管理器中配置的一样。

直到手机打ze睡之后，它才设法在只有手机醒来的屏幕上显示通知。它确实有效，但并非我所期望的。屏幕唤醒仅大约每4-5分钟发生一次，而不是每30秒发生一次。我什至尝试添加另一个警报作业（2个警报计划作业），但仍然无法实现。我的目的是让我的手机至少在触发onReceive（）时显示暗淡显示。我错过了什么？还是我该怎么办？

public class AlarmHelper {
    private static final int PI_SELF_SCHEDULED_ALARM = 1000;
    private static final int PI_REPEATING_ALARM = 1001;

    private final Context context;
    private AlarmManager alarmManager;

    public AlarmHelper(Context context) {
        this.context = context;
        alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE);
    }

    public void setNextSelfSchedulingAlarm() {
        final long fourtySecondsFromNow = System.currentTimeMillis() + SECONDS.toMillis(30);
        Intent exactIntent = new Intent(context, AlarmBroadcastReceiver.class).setAction(SELF_SCHEDULING_ALARM);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, PI_SELF_SCHEDULED_ALARM, exactIntent, FLAG_UPDATE_CURRENT);

        if (SDK_INT >= Build.VERSION_CODES.M) {
            alarmManager.setExactAndAllowWhileIdle(RTC_WAKEUP, fourtySecondsFromNow, pendingIntent);
        } else if (SDK_INT >= Build.VERSION_CODES.KITKAT) {
            alarmManager.setExact(RTC_WAKEUP, fourtySecondsFromNow, pendingIntent);
        } else {
            alarmManager.set(RTC_WAKEUP, fourtySecondsFromNow, pendingIntent);
        }
    }

    public void startRepeatingAlarm() {
        final int repeatingIntervalInSeconds = 30;
        final long tenSecondsFromNow = System.currentTimeMillis() + SECONDS.toMillis(30);
        Intent repeatingIntent = new Intent(context, AlarmBroadcastReceiver.class).setAction(REPEATING_ALARM);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, PI_REPEATING_ALARM, repeatingIntent, FLAG_UPDATE_CURRENT);

        alarmManager.setRepeating(RTC_WAKEUP, tenSecondsFromNow, SECONDS.toMillis(repeatingIntervalInSeconds), pendingIntent);
    }
}

public class AlarmBroadcastReceiver extends BroadcastReceiver {
    private static final String TAG = "AlarmReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        PowerManager.WakeLock screenWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "ScreenLock tag from AlarmListener");

        try {
            screenWakeLock.acquire();

            Hawk.init(context).build();
            String action = intent.getAction();

            if (action == null) {
                screenWakeLock.release();
                return;
            }

            if (REPEATING_ALARM.equals(action)) {
            } else if (SELF_SCHEDULING_ALARM.equals(action)) {
                AlarmHelper alarmHelper = new AlarmHelper(context);
                alarmHelper.setNextSelfSchedulingAlarm();
            }

            Intent intentService = new Intent(context, HeadlessTaskService.class);
            context.startService(intentService);
        } finally {
            screenWakeLock.release();
        }
    }
}

发出RTC_WAKEUP警报，并且BroadcastReceiver拦截打ze睡模式
