关机

AlarmManager取消了RTC_POWEROFF_WAKEUP 不支持通过AlarmManager设置关机唤醒设备。
只有AlarmManager.RTC_WAKEUP 可用

关机实现

    /*** 设备关机. <br/>* 需要系统APP：android:sharedUserId="android.uid.system" <br/>* 需要权限：uses-permission android:name="android.permission.SHUTDOWN" <br/>*/public void setPowerOFF(Long time) {Log.d("Request","powe off intent time:"+time);Intent intent = new Intent(ACTION_REQUEST_SHUTDOWN);//是否显示关机提示dialog，true显示false不显示直接关机intent.putExtra(EXTRA_KEY_CONFIRM, false);intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//获取闹钟的id，给定时设置一个随机id，这样可以设置多个定时器，否则会被覆盖掉int alarmId = getIntRandom();long intervalMillis = 24 * 3600 * 1000;Log.d("Request","powe off alarmId:"+alarmId);PendingIntent pi = PendingIntent.getActivity(mContext, alarmId, intent,  PendingIntent.FLAG_IMMUTABLE);AlarmManager manager = (AlarmManager)mContext.getSystemService(ALARM_SERVICE);//设置重复定时，intervalMillis重复定时的间隔时间。根据自己的需求来设置定时//manager.setRepeating(AlarmManager.RTC_WAKEUP, time, intervalMillis, pi);//设置一次定时，根据自己的需求来设置定时manager.set(AlarmManager.RTC_WAKEUP, time, pi);}

开机实现

高通平台提供了PoweroffAlarm 功能通过调用此系统组件来实现开机

<manifest xmlns:android="http://schemas.android.com/apk/res/android"android:shareUserId="android.uid.system"><uses-permission android:name="org.codeaurora.permission.POWER_OFF_ALARM">

在app端发送广播

    public void setPowerON(Long time) {//发送广播Intent powerOnIntent = new Intent(ACTION_SET_POWEROFF_ALARM);powerOnIntent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);powerOnIntent.setPackage(POWER_OFF_ALARM_PACKAGE);powerOnIntent.putExtra(TIME, time);mContext.sendBroadcast(powerOnIntent);}

具体实现有如下分析

高通提供的关机闹钟实现

	//PowerOffAlarmUtils.javapublic static long setAlarmToRtc(long alarmTime){long currentTime = System.currentTimeMillis();long alarmInRtc = getAlarmFromRtc();long rtcTime = getRtcTime();// calculate the alarm to rtclong timeDelta = alarmTime - currentTime - MS_IN_ONE_MIN;if(timeDelta <= 0){Log.d(TAG, "setAlarmToRtc failed: alarm time is in one miunute");return FAILURE;}long alarmTimeToRtc = timeDelta/SEC_TO_MS + rtcTime;try{IAlarm mProxy = IAlarm.getService(true);int ret = mProxy.setAlarm(alarmTimeToRtc);if(ret == SUCCESS){return alarmTimeToRtc;}else{return FAILURE;}}catch{return FAILURE;}}
