## Understand the tech [#understand-the-tech]
This page tracks Android release notes for the Whiteboard SDK.
## Reference [#reference]
Note
To ensure a consistent user experience across different platforms while enabling native access on each platform, the Whiteboard SDK for Android is implemented by creating a wrapper for the Whiteboard SDK for Web, rather than being a completely native SDK. Therefore, each Android SDK version by default includes the updates of the Web SDK version that it is built upon. The corresponding Web SDK version is provided in each Android release note, so that you can refer to the relevant Web SDK release note for updates.
## v2.16.100 [#v216100]
Released on July 28, 2025.
#### New features [#new-features]
**High-performance whiteboard drawing tools**
This release adds the `appliance-plugin`, a plugin that provides a set of high-performance whiteboard drawing tools. To use it, install `@netless/appliance-plugin` and enable it using the `WhiteSdkConfiguration.enableAppliancePlugin` option. For more details, see the [`appliance-plugin` documentation](https://github.com/netless-io/fastboard/blob/main/docs/zh/appliance-plugin.md).
* `@netless/appliance-plugin` is an external dependency and must be installed separately.
* To ensure correct rendering of strokes, enable the plugin on all platforms (Web, Android, and iOS). If a platform does not enable it, strokes drawn on other platforms will not be visible.
* After enabling the plugin, historical content remains visible but cannot be modified or upgraded. To avoid affecting the user experience, use the plugin on a new whiteboard. Disabling the plugin removes the content drawn with it.
Once enabled, you can:
* Use the `LASER_PENCIL` laser pencil tool. [Learn more](https://github.com/netless-io/fastboard/blob/main/docs/zh/appliance-plugin.md#%E6%96%B0%E5%8A%9F%E8%83%BD)
* Use `MemberState.strokeOpacity` to set line transparency.
* Use `MemberState.fillOpacity` to set fill transparency.
* Use `MemberState.fillColor` to set fill color.
**PPT rendering error handling**
This release adds the `SlideListener.onSlideError` method to listen for PPT rendering errors. If an error occurs, call `WhiteSdk.recoverSlide` to recover rendering.
#### API changes [#api-changes]
**Added**
* `WhiteSdkConfiguration`:
* `enableAppliancePlugin`
* `MemberState`:
* `strokeOpacity`
* `fillOpacity`
* `fillColor`
* `onSlideError`
* `recoverSlide`
## v2.16.86 [#v21686]
Released on July 28, 2025.
Note
The wrapped Web SDK has been upgraded to v2.16.51.
#### New features [#new-features-1]
**Domain preselection**
This version adds the `prepareWhiteConnection` method to preselect an optimal access domain, which can improve the connection speed when users join a whiteboard room for the first time.
#### API changes [#api-changes-1]
**Added**
* `prepareWhiteConnection`
* `ConnectionPrepareParam`
## v2.16.81 [#v21681]
Released on July 28, 2025.
Note
The wrapped Web SDK has been upgraded to v2.16.48.
#### New features [#new-features-2]
**Window apps management**
In the multi-window mode, the SDK supports inserting the PPT or whiteboard plugin as a window. These are collectively referred to as window apps. Starting from this version, the `Room` object has the following new methods for managing window apps in the multi-window mode:
* `addApp`: Inserts a window app and returns the app ID.
* `closeApp`: Closes the window of the specified window app.
* `focusApp`: Switches the focused window to the window of the specified window app.
* `queryApp`: Queries the information of the specified window app.
* `queryAllApps`: Queries the information of all current window apps.
**Custom whiteboard tools**
The `MemberState` has the following new properties for customizing whiteboard tools:
* `textColor`: The color of the text in the text tool.
* `pencilEraserSize`: The size of the pencil eraser tool.
**New PPT rendering configurations**
The `WhiteSdkConfiguration.SlideAppOptions` has the following new properties for PPT rendering configurations:
* `minFPS`: Sets the minimum frame rate for PPT animations.
* `maxFPS`: Sets the maximum frame rate for PPT animations.
* `resolution`: Sets the rendering resolution multiplier for PPT.
* `maxResolutionLevel`: Sets the maximum resolution for PPT.
* `bgColor`: Sets the background color for PPT animations.
* `forceCanvas`: Specifies whether to force 2D rendering. It is disabled by default.
* `enableGlobalClick`: Specifies whether to enable executing the next step function by clicking on the PPT screen. It is enabled by default.
**Whiteboard drawing performance optimization strategy**
The `RoomParams` has a new property `optimizeOptions` for setting the performance optimization strategy for whiteboard drawing. The performance optimization includes the following three methods:
* Adjusting the refresh interval of whiteboard drawing: A lower refresh interval provides smoother stroke display but has a higher performance consumption, while a higher refresh interval makes the stroke appear more laggy but has a lower performance consumption.
* Using single canvas drawing: By default, the whiteboard uses two canvases alternately to avoid flickering on some devices during drawing. Using a single canvas drawing can prevent the need for redrawing and reduce performance consumption.
* Using floating canvas: In the writing scenario, after enabling single canvas drawing, a floating canvas of approximately 256 x 256px is generated based on the drawing position. When subsequent drawing does not exceed the range of this floating canvas, the synchronous drawing of strokes will be limited to this floating canvas instead of the entire canvas, reducing performance consumption.
**Other additions**
This version also includes the following features:
* Adds the `updateText` method for updating the text inserted using `insertText`.
* Adds the `setSyncMode` method for immediately processing whiteboard events and drawing strokes.
* Adds the `setDisableInitialStateCallback` method for disabling the callback of the full state after joining the room.
#### Fixed issues [#fixed-issues]
This version fixes the following issues:
* When `WhiteWindowParams.fullscreen` was enabled, the app did not display in full screen on the second opening.
* When `WindowParams.fullscreen` was enabled, the status bar occasionally flickered.
* Path animation could not return to the original position after page switching.
* Diamond fill filled the entire shape.
* The built-in cursor disappeared after reconnection.
* Occasional flickering when using fade-in and fade-out animations.
* The built-in cursor disappeared after modifying `isWritable`.

#### New features [#new-features-3]
**PPT Volume Control**
This version adds the `getSlideVolume` and `updateSlideVolume `methods to retrieve and update the volume of audio in PPT slides.
**PPT URL Intercept and Replacement**
`WhiteSdkConfiguration` adds a new configuration option, `enableSlideInterrupterAPI`, to enable intercepting and replacing URLs of PPT resources. This feature can be used to encrypt PPT resources uploaded by users and protect their privacy.
Once enabled, the PPT file URL intercept and replacement feature can be implemented by calling `WhiteSdk.setSlideListener(SlideListener)`.
**PPT Rendering Notification**
`WhiteSdkConfiguration` adds the `whiteSlideAppParams` configuration option for displaying configurations related to [@netless/app-slide](https://github.com/netless-io/netless-app/tree/master/packages/app-slide) rendering. Currently, it supports configuring `WhiteSlideAppParams.showRenderError` to show or hide rendering error notifications.
**Custom API Server Domain**
`WhiteSdkConfiguration` adds the `apiHosts` configuration option to configure a list of API server domains for the whiteboard, which can be used for server proxy implementation.
**Custom Module Source**
`RoomParams` adds the `modulesOrigin` configuration option to configure the address for requesting whiteboard module data.
**Document Operation Events**
This release adds the `dispatchDocsEvent` method to send events to the inserted PDF/PPTX documents in the whiteboard, allowing control over document page flipping, page navigation, and slide animation playback.
#### Improvements [#improvements]
**Optimized Document Insertion**
This version optimizes the process of converting and inserting PPT files into the whiteboard using the new document conversion service. You can use the new `createSlideApp` method to construct a `WindowAppParam` object, which includes `ProjectorAttributes` and `ProjectorOptions`, corresponding to the parameters passed when opening the document, see `addApp`.
**Window Fullscreen**
A new property, `WindowParams.fullscreen`, is added to control whether the window is displayed in fullscreen mode.

## v2.16.21 [#v21621]
v2.16.21 was released on September 13, 2022.
#### Compatibility changes [#compatibility-changes-1]
**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: .app)` file as follows:
```text
dependencies {
implementation 'com.github.netless-io:whiteboard-android:'
}
```
For details, see [Get the SDK](/en/realtime-media/whiteboard/build/set-up-and-build-your-first-app/get-started-sdk#get-the-whiteboard-sdk).
#### New features [#new-features-5]
**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.
#### Improvements [#improvements-2]
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.
#### Fixed issues [#fixed-issues-2]
This release fixed the following issues:
* Occasionally, the contents on the whiteboard appeared shifted and overshadowed after users zoomed or moved their view.

## v2.15.0 [#v2150]
v2.15.0 was released on November 16, 2021.
#### Compatibility changes [#compatibility-changes-2]
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](/en/realtime-media/whiteboard/build/set-up-and-build-your-first-app/get-started-sdk#join-the-interactive-whiteboard-room-from-your-app-client).
