Developers can create user interfaces directly on AbilitySlice or on Ability.

A user grants permission X to application A of a certain device, and on the device, application A persists the state of this permission grant and can call all interfaces controlled by permission X at any time.

In the process of developing an application based on HarmonyOS, in order to avoid applying for permissions that are unrelated to the user's required functions, a developer uses the UUID generated by the application instead of the device ID to reduce the permission application. The developer's actions exemplify the principle of applying for permissions in the vicinity.

HarmonyOS application packages are released in the form of application packs, which are composed of one or more HAPs (HarmonyOS Ability Packages) and pack.info describing each HAP attribute.

AbilitySlice and Page have the same lifecycle state and callback method with the same name, and when the Lifecycle of the Page changes, the same lifecycle change will occur in AbilitySlice. Similarly, as the lifecycle of an AbilitySlice changes, the lifecycle state of a Page changes.

Suppose that multiple AbilitySlice are associated in MainAbility, and multiple AbilitySlice are switched in the same page, the lifecycle of MainAbility and all AbilitySlice is synchronized.

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.

JavaScript FA (Feature Ability) lifecycle events are divided into application lifecycle and page lifecycle.

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

Static animation has a start state, an end state and an intermediate state, if you need to set the transition state and transition effect in the middle, you can use static animation to achieve it.

In HarmonyOS, both relational databases and object-relational mapping databases can use SQL statements to manipulate databases.

An engineer uses the WLAN P2P function, and the engineer can establish a P2P group.

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

If a third-party application has registered the callback of the airplane mode setting item in advance, when the user modifies the airplane mode status of the terminal through the system settings, the application will detect the change of this setting item and adapt it. If the airplane mode is detected to be turned off, the app will go offline, and if the airplane mode is detected and turned on, the app will recapture the online data.

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.
