本例子主要由AlertActivity和AlarmService和AlarmAlertWakeLock三个类完成。
AlarmAlertWakeLock主要代码：
public class AlarmAlertWakeLock {
??? private static PowerManager.WakeLock sCpuWakeLock;

??? public static void acquireCpuWakeLock(Context context) {
??????? Log.v("Acquiring cpu wake lock");
??????? if (sCpuWakeLock != null) {
??????????? return;
??????? }
??????? PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);

??????? sCpuWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK
??????????????????????????????????????? | PowerManager.ACQUIRE_CAUSES_WAKEUP
??????????????????????????????????????? | PowerManager.ON_AFTER_RELEASE, Log.LOGTAG);
??????? sCpuWakeLock.acquire();
??? }

??? public static void releaseCpuLock() {
??????? Log.v("Releasing cpu wake lock");
??????? if (sCpuWakeLock != null) {
??????????? sCpuWakeLock.release();
??????????? sCpuWakeLock = null;
??????? }
??? }
}

AlarmService主要用来play()音乐。
