与app的奇怪崩溃

Question

最近我的应用程序崩溃真的很奇怪，如果我启动应用程序，它会提供一秒钟或10秒的白屏，而不是停止工作。

logcat出现以下错误，但我不明白，你们可以帮助我吗？

错误日志太大，请在pastebin上查看： Error log

EDIT ------------------

我认为这段代码会生成错误，它在我添加之后开始： 我只是不确定错误是什么，我不明白logcat输出

{
    Calendar cal = loadCurrentCalendar();
    long currentMil = cal.getTimeInMillis();
    int hourI = cal.HOUR_OF_DAY;

    while (hourI <19)
    {
        currentMil = currentMil + ONE_HOUR;
        hourI ++;
    }
    setSleepMil(currentMil + SLEEP_TIME); // TODO werkt dit ? + SLEEP_TIME stond hier achter currentMil
    return getSleepMil();
}

public int hourPassedSleepCur(long sleepMil)
{
    Calendar cal = loadCurrentCalendar();
    long currentMil = cal.getTimeInMillis();
    hoursPassed = 0;

   while (sleepMil < currentMil)
    {
        hoursPassed ++;
        setSleepMil(getSleepMil()+ ONE_HOUR);
    }
    return hoursPassed;
}

}

EDIT 2-------------------------------------------

Im accessing it with this piece of code witch runs in a thread that checks every few milisec

public void checkSleepyTime()
{
    currentCalendar = timeHelper.loadCurrentCalendar();

    int hour = currentCalendar.get(Calendar.HOUR_OF_DAY);
    int daypart = currentCalendar.get(Calendar.AM_PM);
    if (hour >= 20 && daypart == 1 || hour < 6 && daypart == 0)
    {
        foodButton.setText("ZZzz");
        prefs.edit().remove("foodTime").commit();
        buddy.setSleeping(true);
    }
    else
    {
        buddy.setFoodLevel(buddy.getFoodLevel() - timeHelper.hourPassedSleepCur(loadNextSleepyTime()));
       // buttonTest.setText(timeHelper.hourPassedSleepCur(getNextSleepyTime()));
        saveNextSleepyTime();
        sleepTimeView.setText("sleepy at: " + String.valueOf(loadNextSleepyTime()));
        foodButton.setText("Awake");
        buddy.setSleeping(false);
    }
}
