HarmonyOS Distributed File Service can automatically share files under different accounts.
Correct Answer:
B
Explanation
Service permission checks are a core security mechanism in HarmonyOS. When an application calls a service, the system verifies that the calling app has declared the required permissions in its manifest. Without the proper permission, the service call will be denied. This is foundational to HarmonyOS's permission model and prevents unauthorized access to sensitive services and data.
When a developer is developing an application, he creates a Checkbox component and writes the following code, which of the following descriptions of the code segment is correct?
ohos:height="match_content"
ohos:width="match_content"
ohos:text="This is a checkbox"
ohos:marked="false"
ohostext_color_on=''#000000''
ohos:text_color_off="#FFFFFF"
ohos:text_size="#000000"/>
Correct Answer:
A, C
Explanation
UI updates in HarmonyOS, like most frameworks, must happen on the main thread to avoid thread safety issues and race conditions. All display operations and interface changes are synchronized on this single thread, which is why it's called the UI thread. Background threads can prepare data or perform work, but they must post results back to the main thread for UI updates.
When an Intent is used to initiate a request, if both BundleName and Abilitylame are specified, the application can be started directly according to the full name of the Ability (for example, "com.demcapp.FooAbility").
Correct Answer:
A
Explanation
HarmonyOS migration allows apps to continue execution across devices. The onCompleteContinuation() method is called on the source device after migration finishes successfully. This callback notifies the original app that the migration process has completed and allows it to perform cleanup or logging. The other options do not represent valid lifecycle callbacks for this scenario.
Which of the following is NOT a capability provided by Distributed Device Virtualization in HarmonyOS?
Correct Answer:
B
In the Page Ability lifecycle of HarmonyOS, when the system creates a Page instance for the first time, which of the following callback methods will be triggered first?
Correct Answer:
A
Explanation
The bundleName field in config.json serves as the unique identifier for your application across the HarmonyOS ecosystem. It must match your actual application package name exactly. This identifier is used by the system for installation, launching, permission management, and other app lifecycle operations. Mismatching the bundleName from your package name causes deployment and runtime failures.
