When using EventHandler to implement inter-thread communication, if the callback method of EventHandler and the processing method of EventHandler are used.
The data generated by a developer's use of Data Ability can be shared between different applications on the same device, but cannot be shared across devices.
With the help of HarmonyOS's Al capability, 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 therecognition results. This is by taking advantage of the super-resolution of text and images in AI.
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.
Operations such as the display and update of the UI interface are carried out on the main thread, so the main thread is also called the UI thread.
HarmonyOS's relational database and object relational mapping database are both based on SQLite.
When an application calls a service, the service will check the permissions of the application, and the service cannot be used if there is no corresponding permission.
HarmonyOSdefines different open scopes and authorization methods to protect data according to the sensitivity of the data involved in the interface

3. Call NetManager.getDefaultNet() to get the default data network.
4. Call NetManager.getInstance(Context) to get the instance object of network management.
