Release notes (Whiteboard)

This page provides the release notes for the Interactive Whiteboard SDK.

v2.16.21 was released on September 13, 2022.

SDK integration changes

As of v2.16.0, Agora only updates the netless-io:whiteboard-android GitHub repository; Agora no longer maintains the duty-os:white-sdk-android GitHub repository. When integrating the SDK v2.16.0 or later with JitPack, you need to modify the implementation field under dependencies in the /Gradle Scripts/build.gradle(Module: <projectname>.app) file as follows:

_3

dependencies {

_3

implementation 'com.github.netless-io:whiteboard-android:<version>'

_3

}

For details, see Get the SDK.

1. Inserting text

This release adds the insertText method for inserting text at a specified position.

2. Disabling the stroke effect

This release adds the setDisableNewPencilStroke method to WhiteSdkConfiguration to enable or disable the stroke effect of the pencil. The default value of the disableNewPencilStroke parameter in this method is true, and the SDK enables the stroke effect immediately when you call setDisableNewPencil(false) to enable the new pencil. To disable the stroke effect after setting setDisableNewPencil(false), you can call setDisableNewPencilStroke(true).

This release also adds the isDisableNewPencilStroke method to WhiteSdkConfiguration to get whether the stroke effect of the new pencil is disabled.

3. Getting the scene information

adds the getScene method to the Displayer class, which supports using the scene path to get the information about a specified scene.

This release provides the following improvements:

• Adds tween animation for the new pencil. This allows the SDK to automatically insert frames between keyframes when a user draws or writes with the new pencil, so that remote users see a smoother drawing process. To experience this improvement, ensure that you have called setDisableNewPencil(false) to enable the new pencil.
• Optimizes the writing performance on Android browsers.
• Optimizes the reconnecting mechanism in weak network environment to reduce unnecessary reconnections.

This release fixed the following issues:

• Occasionally, the contents on the whiteboard appeared shifted and overshadowed after users zoomed or moved their view.
• Occasionally, users could not switch the pages of a dynamic PPT slide after an SDK reconnection.
• The contents on the whiteboard occasionally were not fully displayed when users joined a whiteboard room that already had.
• A memory leak sometimes occurred after an SDK reconnection.
• An error sometimes occurred when calling setWritable repeatedly.
• When a user switched to read-only mode, then switched back to read-write mode and wrote, remote users saw that user's cursor as fixed.

Added

• insertText
• setDisableNewPencilStroke
• isDisableNewPencilStroke
• getScene

v2.15.24 was released on January 21, 2022.

To help you manage users in a room, this release adds the uid parameter in RoomParams, for setting the unique identifier of a user.

If you upgrade the SDK to v2.15.0 or later, to avoid affecting your service, ensure that you pass in a string uid in RoomParams when calling joinRoom. The uid of each user cannot be longer than 1024 bytes and must be unique in the same room. For more information, see Join a Whiteboard Room.
