テスト目的で、10秒ごとに情報を取得しようとしているこのAndroidサービスがあります。しかし、私が見ることができることから、サービスは開始されていますが、10秒ごとに更新されていません。何が問題になる可能性がありますか？
これが私のサービスです：

これが私の主な活動です
Intent myIntent = new Intent(Main.this, SimpleService.class);
pendingIntent = PendingIntent.getService(Main.this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 10);
alarmManager.set(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), pendingIntent);
