Structure of the deviceConfig Tag

The deviceConfig tag contains device-specific configuration of the application, including attributes such as default, tv, car, and wearable. The default configuration applies to all types of devices. You need to declare the peculiar configuration of a specific device type in the associated sub-tag of this type.

Internal Structure of the deviceConfig Tag

Table 1 Internal structure of the deviceConfig tag

Name	Description	Data Type	Initial Value Allowed
default	Application configuration that provides full access to system capabilities.	Object	Yes (initial value: left empty)
tablet	Application configuration specific to tablets.	Object	Yes (initial value: left empty)
tv	Application configuration specific to smart TVs.	Object	Yes (initial value: left empty)
car	Application configuration specific to telematics devices.	Object	Yes (initial value: left empty)
wearable	Application configuration specific to wearables.	Object	Yes (initial value: left empty)

For details about the attributes of the deviceConfig tag, see Internal Structure of the deviceConfig Attributes.

Internal Structure of the deviceConfig Attributes

Table 2 Internal structure of the deviceConfig attributes

Name	Description	Data Type	Initial Value Allowed
process	Name of the process running the application or ability. If the process attribute is configured in the deviceConfig tag, all abilities of the application run in this process. You can set the process attribute for a specific ability in the abilities attribute, so that the ability can run in the particular process. The value can contain a maximum of 31 characters.	String	Yes (initial value: left empty)
keepAlive	Whether the application is always running. This attribute applies only to system applications and does not take effect for third-party applications. The value true means that the application will start during the OS startup and keep alive. If the application process exits, the OS will restart it.	Boolean	Yes (initial value: false)
supportBackup	Whether the application supports backup and restoration. The value false means that the application does not support backup or restoration.	Boolean	Yes (initial value: false)
compressNativeLibs	During HAP packaging, whether the libs libraries are packaged to HAP after being compressed. - true: The libs libraries are packaged in the HAP file after being compressed. - false: The libs libraries are stored without being compressed. During application installation, whether the libs library needs to be decompressed. (Since API version 16, this field is supported. In earlier versions, the libs library is decompressed by default.) - true: The libs library is decompressed. - false: The libs library is not decompressed.	Boolean	Yes (During HAP packaging, initial value: false; during application installation, initial value: true)
network	Network security configuration. You can customize the network security settings of the application in the security statement of the configuration file without modifying the application code.	Object	Yes (initial value: left empty)

Internal Structure of the network Attribute

Table 3 Internal structure of the network attribute

Name	Description	Data Type	Initial Value Allowed
cleartextTraffic	Whether to allow the application to use plaintext traffic, for example, plaintext HTTP traffic. - true: The application is allowed to use plaintext traffic. - false: The application is not allowed to use plaintext traffic.	Boolean	Yes (initial value: false)
securityConfig	Network security configuration of the application.	Object	Yes (initial value: left empty)

Internal Structure of the securityConfig Attribute

Table 4 Internal structure of the securityConfig attribute

Name	Description	Data Type	Initial Value Allowed
domainSettings	Security settings of the custom network domain. This attribute allows nested domains. That is, the domainSettings object of a network domain can be nested with the domainSettings objects of smaller network domains.	Object	Yes (initial value: left empty)

Internal Structure of the domainSettings Attribute

Table 5 Internal structure of the domainSettings attribute

Name	Description	Data Type	Initial Value Allowed
cleartextPermitted	Whether cleartext is allowed in the custom network domain. If both cleartextTraffic and security are declared, whether cleartext is allowed in the custom network domain is determined by cleartextPermitted. - true: Cleartext is allowed. - false: Cleartext is not allowed.	Boolean	Yes (initial value: left empty)
domains	Domain name. This attribute consists of two sub-attributes: subdomains and name. - subdomains (boolean): specifies whether the domain name contains subdomains. If it is set to true, the domain naming convention applies to all related domains and subdomains (including the lower-level domains of the subdomains). Otherwise, the convention applies only to exact matches. - name (string): indicates the domain name.	Object array	Yes (initial value: left empty)
