应用内修改

注册

仿照DeskClock源码
注册文件中增加action com.android.deskclock.START_ALARM，接收开机指令然后开机即可
开机参考
alps\vendor\mediatek\proprietary\packages\apps\DeskClock\src\com\android\deskclock\AlarmAlertWakeLock.java

<service android:name=".alarms.AlarmService"
        android:exported="true"
        android:directBootAware="true">
 <!-- M: add intent action for power off alarm to start AlarmService @{ -->
    <intent-filter>
        <action android:name="com.android.deskclock.START_ALARM" />
    </intent-filter>
</service>

设置关机闹钟

参考
alps\vendor\mediatek\proprietary\packages\apps\DeskClock\src\com\android\deskclock\alarms\AlarmStateManager.java

    /// M: [ALPS03269543] [Power off Alarm] @ setPoweroffAlarm if needed {
    public static void setPoweroffAlarm(Context context, AlarmInstance nextAlarm) {
        if (nextAlarm != null && PowerOffAlarm.canEnablePowerOffAlarm()) {
            long timeInMillis = nextAlarm.getAlarmTime().getTimeInMillis();
            Intent stateChangeIntent = createStateChangeIntent(context, ALARM_MANAGER_TAG,
                    nextAlarm, AlarmInstance.FIRED_STATE);
            // Power off alarm should use the different pendingIntent to normal alarm
            PendingIntent pendingIntent = PendingIntent.getBroadcast(context, nextAlarm.hashCode(),
                    stateChangeIntent, PendingIntent.FLAG_UPDATE_CURRENT);
            AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
            LogUtils.v("Set for PowerOffAlarm alarmType = 8, time = "
                    + AlarmUtils.getFormattedTime(context, nextAlarm.getAlarmTime()));
            am.setExact(POWER_OFF_WAKE_UP, timeInMillis, pendingIntent);

            // Add for power_off_alarm to backup the external ringtone
        }
    }
    /** @} */

关键是这一句

am.setExact(POWER_OFF_WAKE_UP, timeInMillis, pendingIntent);
其中 POWER_OFF_WAKE_UP = 7;
这个参数可以从系统的AlarmManager处查得

取消

AlarmManager am = (AlarmManager) context.getSystemService(ALARM_SERVICE);
am.cancelPoweroffAlarm(context.getPackageName());
