#Repeating Screen On by scheduled

use system API Alarm Repeat.
Set how long to repeat the scheduled.
Some notes below:

###AlarmManager

RTC_WAKEUP
RTC
ELAPSED_REALTIME_WAKEUP
ELAPSED_REALTIME

Set Wake up by ScreenLock state

win.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
            | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
            | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
            | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK, "bright");
    //点亮屏幕
    wl.acquire();
    Toast.makeText(context, R.string.repeating_wake,
            Toast.LENGTH_LONG).show();
    //释放
    wl.release();

###关于这个屏幕唤醒

使用系统Alarm API调用循环唤醒
设定AlarmManager的启动方式，看文档4种启动方式的不同，在这就不说明具体使用方法了。
设置休眠状态唤醒有以下2点第一点就是在
```
  setContentView(R.layout.activity_main);
```
之前插入

  final Window win = getWindow();
  win.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
          | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD
          | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
          | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

第二就是在RepeatingAlarm里面调用 PowerManager方法

   PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
  PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK, "bright");
  //点亮屏幕
  wl.acquire();
  Toast.makeText(context, R.string.repeating_wake,
          Toast.LENGTH_LONG).show();
  //释放
  wl.release();

在清单文件加入标注

  <receiver android:name=".RepeatingAlarm" android:process=":remote">
      <intent-filter>
          <action android:name=".AlarmActivity"/>
      </intent-filter>
  </receiver>

目前有BUG问题，停止广播失效，保存时间待添加
08/24 已经解决这个问题由于广播接受者Recevie里面TOAST引起的错误。
