Multimodal Input ChangeLog

cl.multimodalinput.1 Error Information Return Method Change of APIs

The internal APIs of the following modules used service logic return values to indicate error information, which did not comply with the error code specifications of OpenHarmony. Therefore, they are modified in API version 9 and later. - Input device management module (@ohos.multimodalInput.inputDevice.d.ts): third-party APIs

Input consumer module (@ohos.multimodalInput.inputConsumer.d.ts): system APIs
Screen hopping module (@ohos.multimodalInput.inputDeviceCooperate.d.ts): system APIs
Key injection module (@ohos.multimodalInput.inputEventClient.d.ts): system APIs
Input listening module (@ohos.multimodalInput.inputMonitor.d.ts): system APIs
Mouse pointer module (@ohos.multimodalInput.pointer.d.ts): system APIs and third-party APIs

Asynchronous APIs in the preceding modules have the following changes: A parameter check error is returned synchronously; a service logic error is returned via AsyncCallback or the error object of Promise. No change is made to synchronous APIs.

Change Impacts

The application developed based on earlier versions needs to adapt the method for returning API error information. Otherwise, the original service logic will be affected.

off(type: “key”, keyOptions: KeyOptions, callback?: Callback<KeyOptions>): void;

Deprecated APIs: - getDeviceIds(callback: AsyncCallback<Array<number>>): void; - getDeviceIds(): Promise<Array<number>>; - getDevice(deviceId: number, callback: AsyncCallback<InputDeviceData>): void; - getDevice(deviceId: number): Promise<InputDeviceData>;

Substitute APIs: - getDeviceList(callback: AsyncCallback<Array<number>>): void; - getDeviceList(): Promise<Array<number>>; - getDeviceInfo(deviceId: number, callback: AsyncCallback<InputDeviceData>): void; - getDeviceInfo(deviceId: number): Promise<InputDeviceData>;

Changed APIs:

Before change: - supportKeys(deviceId: number, keys: Array<KeyCode>, callback: Callback<Array<boolean>>): void; - getKeyboardType(deviceId: number, callback: Callback<KeyboardType>): void;

After change: - supportKeys(deviceId: number, keys: Array<KeyCode>, callback: AsyncCallback<Array<boolean>>): void; - getKeyboardType(deviceId: number, callback: AsyncCallback<KeyboardType>): void;

Adaptation Guide

The following uses setPointerVisible as an example:

import pointer from '@ohos.multimodalInput.pointer';
pointer.setPointerVisible(true, (error) => {
    console.log(`Set pointer visible success`);
  });

try {
  pointer.setPointerVisible(true, (error) => {
    if (error) {
      console.log(`Set pointer visible failed, error: ${JSON.stringify(error, [`code`, `message`])}`);
      return;
    }
    console.log(`Set pointer visible success`);
  });
} catch (error) {
  console.log(`Set pointer visible failed, error: ${JSON.stringify(error, [`code`, `message`])}`);
}
