有關改進:

現在AlarmClock可以直接播放警告音或震動，而過去必須通過AlarmManager才行，這里AlermManager開始播放通過一個IntentReceiver廣播來實現，這些改變將會阻止從一個模態對話框中出現的警告。(AlarmClock alert now plays audio/vibe directly, rather than through AlarmManager. AlarmClock alert starts playing audio/vibe in its IntentReceiver, rather than on activity start. These changes should prevent alarms from being blocked by modal dialogs. )
