Storage server（后简称storage）以组（卷，group或volume）为单位组织，一个 group 内包含多台 storage 机器，数据互为备份，存储空间以group内容量最小的storage为准，所以建议group内的多个storage尽量配置相同，以免造成存储空间的浪费。
Tracker Server
Tracker 是 fastDFS 的协调者，负责管理所有的 Storage Server 和 group，每个 Storage Server 在启动后会连接 Tracker，告知自己所属的 group 等信息，并保持周期性的心跳，Tracker 根据 Storage 的心跳信息，建立 group ==> [Storage Server List] 的映射表。

1 2 3 4 5 6 7 8 9 10 11 12 13 14
// Adds an Action Button to the Toolbar. // 'icon' is a Bitmap to be used as the image source for the // action button.
// 'description' is a String be used as an accessible description for the button.
// 'pendingIntent is a PendingIntent to launch when the action button // or menu item was tapped. Chrome will be calling PendingIntent#send() on // taps after adding the url as data. The client app can call // Intent#getDataString() to get the url.
// 'tint' is a boolean that defines if the Action Button should be tinted.
//Create a PendingIntent to your BroadCastReceiver implementation Intent actionIntent = new Intent( this.getApplicationContext(), ShareBroadcastReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, actionIntent, 0);
//Set the pendingIntent as the action to be performed when the button is clicked. intentBuilder.setActionButton(icon, shareLabel, pendingIntent);
自定义关闭按钮
