Fastboard API

Reference

FastboardView class

getFastboard

public Fastboard getFastboard()

Get the Fastboard object.

The Fastboard SDK does not support initializing a Fastboard instance directly. To get the Fastboard object, you need to add the FastboardView object to the app's layout, and then call the getFastboard method.

Note

Call this method to obtain the Fastboard object before calling other APIs.

Returns

The Fastboard object is returned when the method call is successful.

Fastboard class

The Fastboard class provides methods for creating FastRoom objects.

createFastRoom

public FastRoom createFastRoom(FastRoomOptions roomOptions)

Create a FastRoom object.

Note

Call this method after obtaining the Fastboard object.

Parameters

• roomOptions: Configuration options for the whiteboard room. See FastRoomOptions for details.

Returns

A FastRoom object is returned when the method call is successful.

preloadWhiteboardView

public static void preloadWhiteboardView() {
    WhiteboardViewManager.get().preload();
}

Preload the whiteboard view.

This method only takes effect when autoPreload in FastboardConfig is set to false. Successfully calling this method will consume memory to perform one whiteboard view preload, improving the speed of joining rooms next time.

destroy

public void destroy()

Destroy the room and release resources.

setConfig

public static void setConfig(FastboardConfig config)

Modifies the auxiliary configuration of the Fastboard object.

Parameters

• config: The auxiliary configuration of the Fastboard object. See FastboardConfig.

• token: String. Room Token of the room, used for user authentication when joining the room. It can be obtained in the following ways:

  • Call the Generate a room token (POST) RESTful API.
  • Build a token generator at your app server. See Generate a token at app server.

• uid: String. The unique identifier of a user in string format. The maximum length is 1,024 bytes. Ensure that the uid of each user in the same room is unique.

• writable: boolean. Whether the user joins the whiteboard room in interactive mode:

  • true: Join the whiteboard room in interactive mode, that is, with read and write permissions.
  • false: Join the whiteboard room in subscription mode, that is, with read-only permission.

• fastRegion: The data center, which must be the same as the data center you chose when creating the whiteboard room. See FastRegion.

• containerSizeRatio: Float. In the local display window, the aspect ratio of the content is 0.56 by default, which is 9:16.

• userPayload: User information displayed by the user's cursor, including the user's nickname and avatar. See FastUserPayload for details.

}

The auxiliary configuration class of the Fastboard object, including the following attributes:

• enablePreload: Boolean. Whether to enable whiteboard preloading:

  • true: Enable whiteboard preloading.
  • false: (Default) Disable whiteboard preloading.

• preloadCount: Integer. The number of WebViews to preload, defaults to 0. The actual effect of this attribute is limited by the memory capacity. You need to adjust the settings appropriately according to the actual situation.

• autoPreload: Boolean. This property only takes effect when enablePreload is true. Whether to enable automatic preloading:

  • true: (Default) Enable automatic preloading. After enabling, whiteboard views will be automatically preloaded to improve loading speed, but will occupy additional memory.

FastRoom class

The FastRoom class provides methods for managing interactive whiteboard real-time rooms.

join [1/2]

public void join()

Join a whiteboard room.

Note

This method needs to be called after the FastRoom object is successfully created.

public void join(@Nullable OnRoomReadyCallback onRoomReadyCallback)

Join a whiteboard room.

Note

This method needs to be called after the FastRoom object is successfully created.

Parameters

• onRoomReadyCallback: OnRoomReadyCallback interface instance. Passing in null means not to register the interface.

OnRoomReadyCallback

The OnRoomReadyCallback interface is used to send room event notifications to the app and includes the following member methods:

void onRoomReady(FastRoom fastRoom);

Room ready callback.

Parameters

• fastRoom: FastRoom object.

isReady

public boolean isReady()

Get whether the room is ready.

After calling the join method, you need to call this method to get whether the room is ready. After the room is ready, other methods in the FastRoom class can be called to operate the whiteboard.

Returns

Is the room ready?

• true: ready.
• false: Not ready yet.

isWritable

public boolean isWritable()

Get whether the local user's current interactive whiteboard real-time room is in interactive mode.

• false: Subscription mode, that is, with read-only permissions.

redo

public void redo()

Redo, that is, roll back the undo operation.

setWritable [1/2]

public void setWritable(boolean writable)

Set whether the user is in interactive mode in the room.

Note

This method needs to be called after the room is ready.

Parameters

• writable: whether the user is in interactive mode in the room:

  • true: interactive mode, that is, with read and write permissions.
  • false: Subscription mode, that is, with read-only permissions.

setWritable [2/2]

public void setWritable(boolean writable, FastResult<Boolean> result)

Set whether the user is in interactive mode in the room.

Parameters

• writable: whether the user is in interactive mode in the room:

  • true: interactive mode, that is, with read and write permissions.
  • false: Subscription mode, that is, with read-only permissions.

• result: The result of the setWritable method call. See FastResult for details. Passing in the FastResult instance, the SDK will trigger the callback implemented in the FastResult interface and report whether the setWritable method call is successful; passing in null means not to listen to the callback.

registerApp

Registers a third-party window application to the whiteboard room.

public void registerApp(FastRegisterAppParams params, FastResult<Boolean> result)

This method allows you to register external applications that can run as independent windows within the whiteboard.

2. Remote package registration: Uses a remote URL (may fail due to network issues)

Parameters

• params: Registration parameters, including app configurations. See FastRegisterAppParams for details.
• result: The result of the registerApp method call. See FastResult for details. If you pass a FastResult instance, the SDK triggers the callback implemented in the FastResult interface to report whether the registerApp method call was successful. Passing null means the callback is not listened to.

FastRegisterAppParams

public class FastRegisterAppParams {
    private String javascriptString;
    private String kind;
    private String url;

    }

    public FastRegisterAppParams(String url, String kind, Map<String, Object> appOptions) {
        this.url = url;
        this.kind = kind;
        this.appOptions = appOptions;
    }

    public String getJavascriptString() {
        return javascriptString;
    }

    public String getKind() {
        return kind;
