Android 由AlarmManager每天在特定时间启动服务不工作

我想每天在特定的时间启动服务，然后每分钟发送一次服务启动通知，单独运行服务很好，但是当alarmmanager调用服务时，什么也没有发生

此处显示报警代码：

Calendar cur_cal = new GregorianCalendar();
cur_cal.setTimeInMillis(System.currentTimeMillis());//set the current time and date for this calendar

Calendar cal = new GregorianCalendar();
cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
cal.set(Calendar.HOUR_OF_DAY, 20);
cal.set(Calendar.MINUTE, 23);
cal.set(Calendar.SECOND, cur_cal.get(Calendar.SECOND));
cal.set(Calendar.MILLISECOND, cur_cal.get(Calendar.MILLISECOND));
cal.set(Calendar.DATE, cur_cal.get(Calendar.DATE));
cal.set(Calendar.MONTH, cur_cal.get(Calendar.MONTH));
Intent intent = new Intent(this, NotifService.class);
PendingIntent pintent = PendingIntent.getBroadcast(this, 0, intent, 0);
AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 30 * 1000, pintent);

这里是NotiService.Class：

public class NotifService extends Service {

    ScheduledExecutorService scheduler = Executors.newSingleThreadScheduledExecutor();
    private static final int HELLO_ID = 1;

    @Override
    public IBinder onBind(Intent arg0) {

        return null;
    }

    @Override
    public void onStart(Intent intent, int startId) {

        super.onStart(intent, startId);
        final Intent intent1 = new Intent(this, DialogoActivity.class);

        scheduler.scheduleWithFixedDelay(new Runnable() {

            @Override
            public void run() {

                // Look up the notification manager server
                NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

                // Create your notification
                //int icon = R.drawable.ic_launcher;
                CharSequence tickerText = "Dominion";
                //long when = System.currentTimeMillis();
                //Notification notification = new Notification(icon, tickerText, when);
                Context context = getApplicationContext();
                CharSequence contentTitle = "your turn";
                String contentText = "click here";

                PendingIntent pIntent = PendingIntent.getActivity(NotifService.this, 0, intent1, 0);

                Notification notification = new NotificationCompat.Builder(getApplicationContext()).setContentIntent(pIntent).setTicker(tickerText).setContentTitle(contentTitle).setContentText(contentText).setSmallIcon(R.drawable.ic_launcher).addAction(R.drawable.ic_launcher, "Si", pIntent).setVibrate(new long[] {100, 250, 100, 500}).build();

                notification.flags |= Notification.FLAG_AUTO_CANCEL | Notification.FLAG_SHOW_LIGHTS;
                // Send the notification

                nm.notify(HELLO_ID, notification);
            }
        }, 1, 1, TimeUnit.MINUTES);
    }

    @Override
    public void onDestroy() {

        super.onDestroy();
    }
}

可能是您没有在Manifest.XML中声明您的服务

请参阅：

广播接收器是否实际调用它？您可能需要从服务而不是广播调用挂起的意图请参阅PendingEvent.getService（上下文、请求代码、意图、标志）我尝试了PendingEvent.getService（上下文、请求代码、意图、标志），但没有任何错误，但也不起作用
