AlarmManager无法启动该服务

Question

我正在使用AlarmManager在特定时间启动服务，该服务应在调用时发送通知。但是当应用程序在后台被终止或停止时，似乎AlarmManager不起作用。

我的代码： （MainActivity）

public void setMobile(String mob) {
    mobile = mob.chars().allMatch(Character::isDigit)? mob : mobile;
}

服务：

    Intent iNotifikace = new Intent(context, Notifikace.class);
    PendingIntent notifikace = PendingIntent.getBroadcast(this, 0, iNotifikace, 0);
    alarmMgr = (AlarmManager) context.getSystemService(ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(time));

    alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, notifikace);

BootReceiver：

public class Notifikace extends IntentService {


public Notifikace() {
    super("Notifikace");
}

@Override
public void onCreate() {

    super.onCreate();
}

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

    super.onStart(intent, startId);
}


@Override
protected void onHandleIntent(Intent intent) {


}@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    HandlerThread thread = new HandlerThread("Thread Name");
    Intent i = new Intent(context, Notifikace.class);
                    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, i, 0);
                    mBuilder.setContentIntent(pendingIntent);
                    mBuilder.setSmallIcon(R.drawable.ic_launcher)
                            .setContentTitle("Notification")
                            .setContentText("NotificationText");
                    mBuilder.setAutoCancel(true);
                    NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                    mNotificationManager.notify(002, mBuilder.build()); stopSelf();


    return START_NOT_STICKY;
    }}

public class BootReceiver extends BroadcastReceiver {

private AlarmManager alarmMgr;
private SharedPreferences sharedPref;

@Override
public void onReceive(Context context, Intent intent) {

    sharedPref = PreferenceManager.getDefaultSharedPreferences(context);
    String time = sharedPref.getString("pref_time", "16");

    Intent iNotifikace = new Intent(context, Notifikace.class);
    PendingIntent notifikace = PendingIntent.getService(context, 0, iNotifikace, 0);
    alarmMgr = (AlarmManager) context.getSystemService(ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.set(Calendar.HOUR_OF_DAY, Integer.parseInt(time));



    alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, kontrolaZastupovani);
}}
