Standby Doze

API19开始AlarmManager机制修改
应用程序被Kill掉后,设置的闹钟不响
6.0以上进入Doze模式会使JobScheduler停止工作
手机设置重启后，闹钟失效问题

PendingIntent pi = PendingIntent.getxxx;
AlarmManager alarm = (AlarmManager) cxt.getSystemService(Context.ALARM_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) //Android 6，针对省电优化Doze模式
alarm.setExactAndAllowWhileIdle(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + delay, pi);
else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) //Android 4.4，针对set不准确
alarm.setExact(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + delay, pi);
else
alarm.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + delay, pi);
