UIAbility configuration of the module, which is valid only for the current UIAbility component.
**By default, application icons cannot be hidden from the home screen in OpenHarmony.**
The OpenHarmony system imposes a strict rule on the presence of application icons. If no icon is configured in the HAP file of an application, the system uses the icon specified in the **app.json** file as the application icon and displays it on the home screen.
Touching this icon will direct the user to the application details screen in **Settings**, as shown in Figure 1.
To hide an application icon from the home screen, you must configure the **AllowAppDesktopIconHide** privilege. For details, see [Application Privilege Configuration Guide](../../device-dev/subsystems/subsys-app-privilege-config-guide.md).
**Objectives**:
This requirement on application icons is intended to prevent malicious applications from deliberately configuring no icon to block uninstallation attempts.
**Setting the application icon to be displayed on the home screen**:
Set **icon**, **label**, and **skills** under **abilities** in the **module.json5** file. In addition, make sure the **skills** configuration contains **ohos.want.action.home** and **entity.system.home**.
```
{
"module":{
...
"abilities": [{
"icon": "$media:icon",
"label": "Login",
"skills": [{
"actions": ["ohos.want.action.home"],
"entities": ["entity.system.home"],
"uris": []
}]
}],
...
}
}
```
**Display rules of application icons and labels on the home screen:**
* The HAP file contains UIAbility configuration.
* The application icon on the home screen is set under **abilities** in the **module.json5** file.
* The application does not have the privilege to hide its icon from the home screen.
* The application icon displayed on the home screen is the icon configured for the UIAbility.
* The application label displayed on the home screen is the label configured for the UIAbility. If no label is configured, the bundle name is returned.
* The name of the UIAbility is displayed.
* When the user touches the home screen icon, the home screen of the UIAbility is displayed.
* The application has the privilege to hide its icon from the home screen.
* The information about the application is not returned during home screen information query, and the icon of the application is not displayed on the home screen.
* The application icon on the home screen is not set under **abilities** in the **module.json5** file.
* The application does not have the privilege to hide its icon from the home screen.
* The application icon displayed on the home screen is the icon specified under **app**. (The **icon** field in the **app.json** file is mandatory.)

**Objectives**:
**By default, application icons cannot be hidden from the home screen in OpenHarmony.**
This requirement on application icons is intended to prevent malicious applications from deliberately configuring no icon to block uninstallation attempts.
OpenHarmony strictly controls applications without icons to prevent malicious applications from deliberately configuring no icon to block uninstall attempts.
**Setting the application icon to be displayed on the home screen**:
Set **icon**, **label**, and **skills** under **abilities** in the **config.json** file. In addition, make sure the **skills** configuration contains **ohos.want.action.home** and **entity.system.home**.

**Display rules of application icons and labels on the home screen:**
To hide an application icon from the home screen, you must configure the **AllowAppDesktopIconHide** privilege. For details, see [Application Privilege Configuration Guide](../../device-dev/subsystems/subsys-app-privilege-config-guide.md). The rules for displaying the entry icon and entry label are as follows:
* The HAP file contains Page ability configuration.
* The application icon on the home screen is set under **abilities** in the **config.json** file.
* The application does not have the privilege to hide its icon from the home screen.
* The application icon displayed on the home screen is the icon configured for the Page ability.
* The application label displayed on the home screen is the label configured for the Page ability. If no label is configured, the bundle name is returned.
* The name of the Page ability is displayed.
* When the user touches the home screen icon, the home screen of the Page ability is displayed.
* The system uses the icon configured for the Page ability as the entry icon and displays it on the home screen. Touching this icon will direct the user to the home page of the Page ability.
* The system uses the label configured for the PageAbility as the entry label and displays it on the home screen. If no label is configured, the bundle name is returned.
* The application has the privilege to hide its icon from the home screen.
* The information about the application is not returned during home screen information query, and the icon of the application is not displayed on the home screen.
* The application information is not returned when the home screen queries the information, and the entry icon and label of the application are not displayed on the home screen.
* The application icon on the home screen is not set under **abilities** in the **config.json** file.
* The application does not have the privilege to hide its icon from the home screen.
* The application icon displayed on the home screen is the default icon.
* The application label displayed on the home screen is the bundle name of the application.
* Touching the application icon on the home screen will direct the user to the application details screen shown in Figure 1.
* The system uses the default icon as the entry icon and displays it on the home screen. Touching this icon will direct the user to the application details screen under application management, as shown in Figure 1.
* The system uses the bundle name of the application as the entry label and displays it on the home screen.
