Question

使用AlarmManager以确切的时间间隔运行IntentService时出现问题。首先，我想提一下，我知道自API级别19以来的警报变化，我有一个正确的处理方式：

public static void setServiceAlarm(Context con, long offset, boolean isOn, long lastHandledStamp){
    Intent i = new Intent(con, StService.class);
    Bundle extra = new Bundle();
    extra.putLong(EXTRA_TIMESTAMP, lastHandledStamp);
    i.putExtras(extra);

    PendingIntent pending = PendingIntent.getService(con, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);

    AlarmManager manager = (AlarmManager) con.getSystemService(Context.ALARM_SERVICE);
    if (isOn){
        if (Build.VERSION.SDK_INT < 19) {
            //for versions 19 and above all repeating alarms are inexact
            Log.i(TAG, "Version below 19, setting repeating alarm");
            manager.setRepeating(AlarmManager.RTC, System.currentTimeMillis(), INTERVAL, pending);
        } else {
            manager.setExact(AlarmManager.RTC, System.currentTimeMillis() + offset, pending);
        }
    } else {
        manager.cancel(pending);
        pending.cancel();
    }
}

这是我用来设置确切警报的方法。然而，这似乎并没有起作用。我正在运行API 22并在我的IntentService i日志中运行服务。它应该每15秒运行一次，这就是我得到的

正如您所看到的，服务是以随机间隔启动的，这在我的情况下是不可接受的。有什么问题，我该如何解决？
