cl.window.1 Input_KeyEvent Injection Changed in the Callback Event Registered by OH_NativeWindowManager_RegisterKeyEventFilter

Access Level

Public API

Reason for Change

The injected value does not match the enumerated value when the Input_KeyEventAction field of the Input_KeyEvent struct is injected into the callback function. Before the change, the values 1, 2, and 3 of Input_KeyEventAction correspond to KEY_ACTION_CANCEL, KEY_ACTION_DOWN, and KEY_ACTION_UP, respectively, whereas the enumerated values are 0 (KEY_ACTION_CANCEL), 1 (KEY_ACTION_DOWN), and 2 (KEY_ACTION_UP).

Change Impact

This change is a non-compatible change.
Before the change, the value of Input_KeyEventAction in Input_KeyEvent is 1, 2, or 3, which does not match the enumerated values.
After the change, the value of Input_KeyEventAction in Input_KeyEvent is 0, 1, or 2, which matches the enumerated values.

Start API Level

API version 12

Change Since

OpenHarmony SDK 5.0.0.38

Key API/Component Changes

Injection implementation of the callback function OH_NativeWindowManager_KeyEventFilter registered by calling OH_NativeWindowManager_RegisterKeyEventFilter

Adaptation Guide

Change the code to the corresponding enumerated values of Input_KeyEventAction.

cl.window.2 Startup Behavior of startAbility and openLink Is Restricted on a Lock Screen

Access Level

Public API

Reason for Change

Added restrictions on the behavior of randomly starting applications when the screen is locked.

Change Impact

This change is a non-compatible change.

Before the change: When the screen is locked, the startAbility and openLink APIs can be called to start an application and keep the application window in the foreground.

After the change: When startAbility or openLink is called to start an application on a lock screen, the application window is blocked by the window manager when it attempts to enter the foreground state, and the window and application are closed.

Start API Level
