In the Javascript UI framework, to realize the jump between pages, you need to specify the uri in the page routing router to find the target page.

If a developer wants to develop a file background download function, there needs to be a Page Ability to provide U pages, and a Service Ability to provide the background file download function. If you want to perform some operations after connecting to the Service Ability in the Page Ability, you need to implement the onAbilityConnectDone() method in the Page Ability.

Service is running in the background, and users want the application to keep running all the time when playing music, and the foreground Service cannot be used at this time.

HarmonyOS provides the Al capability of Instant Messaging (IM) intent, which can convert speech signals into text or commands, and identify the user's intent represented by the message content.

In order to improve the image quality of network source images, developers can use the Instant Messaging (IM) class intent recognition interface provided by HarmoyOS.

The MainAbility of a HarmonyOS application has multiple AbilitySlices, and when the AbilitySlice health state is switched, the MainAbility state is INACTIVE.

Cross-terminal migration is a technical solution to realize the flow of user applications, which refers to the simultaneous or alternate operation of FA/PA on multiple terminals to achieve complete services.

HarmonyOS maintains a stack of AbilitySlice instances for each Page, and each AbilitySlice instance that enters the foreground will be added to the stack.

In HarmonyOS, when switching between pages, if you use Ability Switching, it is equivalent to constantly switching new pages in the same window, and if you use AbilitySlice to switch, a new window will pop up.

A developer wants to use the list component of the JavaScript UI framework to display a table.

< list class="todo-wraper"

scrollpage="true"

scrollbar="on"

shapemode="round"

scrolleffect="no" >

< list-item for="{{todolist}}"class="todo-item" >

< text class="todo-title" > {{Sitem.title}} < /text >

< text class="todo-title" > {{Sitem.date}} < /text >

< /list-item >

< /list >

When using DevEco Studio for debugging, you need to check the properties in configjson regardless of whether you use a real machine or an emulator.

On the basis of the supported input events, the multi-mode input defines some input actions commonly used by users as a set of standardized events, and maps the input events of different input devices to the standardized events.

In order to solve the problem of safety risks when walking or cycling, a travel navigation company uses HarmoryOS to push mobile navigation reminders to its watch.

Encoding is the process of converting information from one form or format to another, which of the following can be encoded?

If there are different components in the layout with the same ID, when the component is searched by ID, the last component found will be returned.
