Distributed data services can isolate data belonging to different applications to ensure that data between different applications cannot be accessed to each other through distributed data services.
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 a developer starts a music player on a remote device, he or she may not fill in the Deviceld of the remote device.
The callback mechanism provided by the Ability class can allow the Page instance to switch with the user's operation background
Sampling refers to the process of sampling a digital signal in a continuous time domain at certain time intervals to obtain a discrete signal in the discrete time domain.
In HarmonyOS's "1+8+N" strategy, mobile phones belong to one of the "8" devices.
MATCH_CONTENT indicates that the component size will expand to the maximum allowed by the parent component and occupy the remaining size in the direction of the parent component
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.
When users use mobile phones, they will find that the phone number in the text message is often highlighted, and they can dial directly. This is a typical application scenario for entity recognition Al.
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.
In HarmonyOS, both relational databases and object-relational mapping databases can use SQL statements to manipulate databases.
A developer uses the Wi-Fi "Don't TrustHot-spotConfiguration" feature provided by HarmonyOS to add a specifiedhot-spotto its application, making it prioritize lower than the saved hot-spot. In this case, the system will refuse to connect to thehot-spoteven if it is the most suitablehot-spotafter the system scan.
A manufacturer used HarmonyoS to produce a dash cam (memory is 64MB), which is small in size and light in weight, and is a lightweight system device.
On the basis of the supported input events, HarmonyOS's multi-dimensional input defines some input actions commonly used by users as a set of standardized events, maps the input events of different input devices to the standardized events, and can obtain a unified experience when using multiple input devices to operate different terminal devices or applications.
HarmonyOS provides the NFC message notification function, through which developers can obtain the message of the NFC switch state change and the NFC field strength message.
