Before starting the debugging of the Entry module, the engineer needs to check whether the "visible" attribute exists in the config.jsnabilities array in the config.jsnabilities file under the Entry module, and if it does not exist, it needs to be added manually, otherwise the debugging of the Entry module cannot enter the breakpoint.

The Service Ability created by a developer does not have a user interface. Can be launched by other apps. When the user switches to another application, the Service will be killed in the background.

In JavaScript UI development, for wearable projects and TV projects, the name of the homepage can be not index, and the first page in the pages configuration list is the homepage; for the litewearable project, the name of the homepage must be index.

A Page Instance can contain a group of related pages, and each page is represented by an AbilitySlice instance.

When developing the list component in the JavaScript UI framework, you can use the data of the Map type to dynamically bind the data.

A HarmonyOS developer uses syncDispatch to synchronously dispatch tasks when developing applications. In this scenario, syncDispatch dispatches the task and waits for the task to complete on the current thread, so the current thread is not blocked until it returns.

A developer needs to use the JavaScript UI framework to display the bar chart of the current month's product sales, and can use the chart component to achieve this function.

With the help of the AI-enabled capabilities of HarmonyOS, it can detect and recognize the text of image sources such as document remakes and street view reproductions, and can also be integrated into other applications to provide text detection and recognition functions, and provide translation, search and other related services based on the recognition results. This is by taking advantage of the super-resolution of text and images in AI.

When installing the HarmonyOS application development environment, if the network can directly access the Internet, developers need to set up Gradle and NPM agents to configure the development environment correctly.

Frame rate is the frequency (rate) at which a bitmap image appears continuously on a display in frames, measured in hertz (Hz).

If the third-party library used by the developer involves permission management, the permission needs to be declared one by one in the config.json file of the application.

After the user enters a piece of text, with the help of the part-of-speech annotation interface, the application can perform automatic word segmentation, and label each word in the word segmentation result with a correct part of speech. However, the part-of-speech tagging feature provided by HarmonyOS only provides a fixed word segmentation granularity, and developers cannot customize the word segmentation granularity as needed when developing applications.

When MainAbility and MainAbiitySlice are bound together, the lifecycles of the two are synchronized, including the callback method for transitioning between states.

HarmonyOS's distributed soft bus enables distributed management of application data and user data.

Intent is a carrier for transmitting information between objects.
