Android Vold架构（二）

1. 总体架构

2. 流程概览

2.1 开启Vold

2.2 引导Uevent

2.3 处理事件

 static const char *stateToStr(int state) {
    if (state == Volume::State_Init)
        return "Initializing";
    else if (state == Volume::State_NoMedia)
        return "No-Media";
    else if (state == Volume::State_Idle)
        return "Idle-Unmounted";
    else if (state == Volume::State_Pending)
        return "Pending";
    else if (state == Volume::State_Mounted)
        return "Mounted";
    else if (state == Volume::State_Unmounting)
        return "Unmounting";
    else if (state == Volume::State_Checking)
        return "Checking";
    else if (state == Volume::State_Formatting)
        return "Formatting";
    else if (state == Volume::State_Shared)
        return "Shared-Unmounted";
    else if (state == Volume::State_SharedMnt)
        return "Shared-Mounted";
    else
        return "Unknown-Error";
}

 

TF 插入状态：

from  0 (No-Media) to 2 (Pending)

 from 0 (No-Media) to 2 (Pending)

 from 2 (Pending) to 1 (Idle-Unmounted)

 from 1 (Idle-Unmounted) to 3 (Checking)

from 2 (Pending) to 1 (Idle-Unmounted)

from 1 (Idle-Unmounted) to 3 (Checking)

from 3 (Checking) to 4 (Mounted)

from 3 (Checking) to 4 (Mounted)

 

Vold - Volume Daemon存储类的守护进程，作为Android的一个本地服务，负责处理诸如SD、USB等存储类设备的插拔等事件。

1. 总体架构

Vold服务由volumeManager统一管控，它将具体任务分别分派给netlinkManager, commandListener, directVolume, Volume去完成。

Vold服务向下通过socket机制与底层驱动交互，向上通过JNI, intent, socket, doCommand等机制与Java Framework交互。

 

 2 流程概览

2.1 开启服务

初始化Android系统时开启Vold本地服务，

Vold在/dev/block下创建vold文件夹，开启VolumeManager, NetlinkManager, CommandListener。

2.2 引导Uevent

NetlinkManager负责监听底层Linux上报的uevent事件。

 

系统的SocketListner统一管理所有socket事件。

NetlinkListner负责解析socket事件。

最后由onEvent()将vold事件交还给NetlinkManager处理。

2.3 处理Block和Switch事件

NetlinkManager调用VolumeManager中处理vold事件的类。

handleBlockEvent()完成SD的挂载和卸载，具体交由DirectVolume完成。

handleSwitchEvent()完成由USB实现的U盘的连接。

两者最后都是通过setBroadcast()将ResponsibleCode经过nativeDaemonConnector的socket监听机制，最终上传到MountService作统一规划。

MountService里的onEvent()得到解析后的事件，完成两大任务，

-> 发送命令doCommand()通过commandListener传递给volumeManager

-> 将事件信息广播给相关服务，供上层应用使用。
