Release notes (Fastboard)

This page provides the release notes for the Fastboard.

The Fastboard SDK is the latest generation of the Interactive Whiteboard SDK launched by Agora to help developers quickly build whiteboard applications. It simplifies the APIs of the Interactive Whiteboard SDK and implements the core functionality with a default user interface (UI). In addition, the Fastboard SDK integrates window-manager and extensions from netless-app to allow developers to easily extend the functionality of their whiteboard applications. With the Fastboard SDK, you do not need to learn the complex concepts of the interactive whiteboard; you can join a whiteboard room with a few lines of code and instantly use the rich editing tools to start real-time interactive collaboration.

Released on July 28, 2025.

• Register third-party window apps

  This version adds the registerApp method to the FastRoom class, allowing you to register third-party window apps in the whiteboard room. This method enables the registration of external applications that can run as independent windows on the whiteboard, and supports two registration methods:

  • Local script registration: Uses local JavaScript code (recommended for its high reliability)
  • Remote package registration: Uses a remote URL (may fail due to network issues)

  Additionally, the FastRegisterAppParams class is introduced to configure registration parameters, including options such as app name, script code, and URL.

  caution

  • You must complete the registration before joining the room to ensure the application loads correctly.
  • Ensure that all clients use the same version of the application to avoid runtime issues.

• Set stroke thickness range

  This version introduces the setStrokeRange method in the FastUiSettings class, which allows you to set the range of the line width slider in the toolbox. This method configures the minimum and maximum values of the line width slider in the toolbox extension panel. Users can adjust the line width within this range when using drawing tools like pencil, rectangle, circle, etc. The default range is 1 to 24.

• The setToolboxEdgeMargin method did not work when Toolbox Gravity was not specified.
• UI updates did not take effect on the first call of setResource.
• The brush color was not in the custom color list when first entering the room after setting it with setToolsColors, which was not expected.

• Added

  • registerApp
  • FastRegisterAppParams
  • setStrokeRange

Released on July 28, 2025.

• Manual loading of whiteboard view

  This version adds the preloadWhiteboardView method, which is used to manually perform a whiteboard view preload to improve the speed of joining the room next time. Before using this feature, ensure that the autoPreload in FastboardConfig is set to false.

• Insert Documents

  The FastRoom class adds the insertStaticDoc and insertPptx methods to insert static docs and dynamic PPT docs, respectively.

• Whiteboard Preloading

  Adds the FastboardConfig class for auxiliary configuration of the Fastboard object. You can modify the configuration by calling the setConfig method. Among them, FastboardConfig.enablePreload and FastboardConfig.preloadCount are used to switch the whiteboard preloading function and specify the number of WebViews to be preloaded respectively. After configuration, the whiteboard loading speed can be improved.

• New Whiteboard Tools

  This release adds the following new whiteboard tools:

  • Adds pencil eraser tool FastAppliance.PENCIL_ERASER to erase local pencil strokes.
  • Adds grab tool FastAppliance.HAND to move the view.

• Whiteboard Logging

  Adds the FastLogger class to provide a flexible whiteboard runtime log recording tool, which can easily record four different levels of log information: debug, info, warn, and error . You can call the setLogger method to customize the logger to adapt to different logging needs, or you can use the system Log class to log.

• When calling the Fastroom.insertImage method to insert an image, the image will be centered in the current view by default.
• The room state callback, roomState, which is triggered after joining a whiteboard room, is disabled. You need to call Room.getRoomState() to get the complete RoomState.

v1.3.4 was released on January 19, 2024.

API rename

The setStokeWidth method under the FastRoom class is renamed to setStrokeWidth. See setStrokeWidth.

Modify whiteboard color

This version adds the FastResource class, which provides a series of methods for modifying color matching, including:

• getBackgroundColor: Configure the background color of the Fastboard control.
• getBoardBackgroundColor: Configure the background color of the whiteboard.

Set window ratio

This version adds a new containerSizeRatio attribute in the FastRoomOptions class, which is used to modify the ratio of the height and width of the local display window content.

Show user cursor

This version adds a new userPayload attribute in the FastRoomOptions class, which is used to synchronize and display the position of the user cursor in the whiteboard room.

Set room read and write permissions

This version adds a new setWritable method under the FastRoom class, which is used to set the current room to interactive mode or read-only mode, and a new isWritable method to get whether the current whiteboard room is in interactive mode. In a large class scenario, setting the room to read-only mode can improve the stability of the whiteboard room connection and the upper limit of the number of people the room can accommodate.

Adjust toolbar margins

This version adds a new setToolboxEdgeMargin method under the FastUiSettings class, which is used to adjust the margins of the whiteboard toolbar.

Support for the new file conversion service

This release adds the following properties to the FastInsertDocParams class to support the new file conversion service:

• dynamicDoc: Boolean. Whether the type of the conversion task is dynamic.

• converterType: Enum. The version of the file conversion service. Contains the following enumerators:

  • Projector: The new file conversion service. See File conversion overview.
  • WhiteboardConverter: The old file conversion service (default). See Deprecated file conversion overview.

This version optimizes the overall performance of the user interface and adjusts the whiteboard tool icon style and the default margins of the whiteboard toolbar.

This version fixes the following issues:

• The order of the parameters in the FastInsertDocParams class.
• An issue that could cause the text tool to lose focus when using it.

v1.2.0 was released on May 25, 2022.

1. Configuring controls on the whiteboard user interface

• setToolsColors: Sets the color set of the palette.

• setToolboxGravity: Sets the position of the toolbar on the whiteboard.

2. Configuring the style of the whiteboard user interface

This release adds the setFastStyle method to the FastRoom class for setting the style of the whiteboard user interface. You can use this method to modify the theme color and mode of the whiteboard user interface.

v1.0.0 was released on March 6, 2022. This is the first official release of the UI Kit for Android.

Implementations of the core whiteboard functionality and user interface (UI)

This release directly implements the basic functions of the interactive whiteboard with a default UI. After integrating the UI Kit and calling join to join the whiteboard room, you can use the following functions:

• The whiteboard toolbar, which includes all basic whiteboard editing tools, such as pencil, text editor, and shape tools. It also supports setting stroke width, font size, and stroke color.

• The whiteboard page control, which enables you to add and switch whiteboard pages.

• The view control, which you can use to zoom in and out of the current whiteboard page and adjust the view.

• Undo and redo an action.

In addition, the UI Kit provides the following APIs to enable you to implement these functions with customized UIs:

• setAppliance

• setStrokeWidth

• setStrokeColor

• undo

• redo

The UI Kit supports inserting and displaying files in multiple formats on the whiteboard, such as images in PNG and JPG formats, audio and video in MP3 and MP4 formats, and documents in PPT, PPTX, DOC, DOCX, and PDF formats. For detailed implementation steps, see Display Files.

Refer to the following documentation to integrate the UI Kit and add the whiteboard functionality to your project:

• Join a Whiteboard Room: Describes how to quickly join a whiteboard room and experience interactive whiteboard features using the UI Kit.

• Display Files: Describes how to call the UI Kit's APIs to insert images, play audio and video, and present documents on the whiteboard.

• API Reference: Provides a detailed API reference for the UI Kit.
