Application Package Structure Configuration File

When developing an application in the Feature Ability (FA) model, you must declare the package structure of the application in the config.json file.

Internal Structure of the config.json File

The config.json file consists of three mandatory tags, namely, app, deviceConfig, and module. For details, see Table 1.

Table 1 Internal structure of the config.json file

app	Global configuration of the application. Different HAP files of the same application must use the same app configuration. For details, see Internal Structure of the app Tag.	Object	No
deviceConfig	Application configuration applied to a specific type of device. For details, see Internal Structure of the deviceconfig Tag.	Object	No
module	Configuration of a HAP file. It is valid only for the current HAP file. For details, see Internal Structure of the module Tag.	Object	No

The app tag contains the global configuration information of the application. For details about the internal structure, see Table 2.

Table 2 Internal structure of the app tag

Attribute	Description	Data Type	Initial Value Allowed
bundleName	Bundle name, which uniquely identifies an application. The bundle name can contain only letters, digits, underscores (_), and periods (.). It must start with a letter. The value is a string with 7 to 127 bytes of a reverse domain name, for example, com.example.myapplication. It is recommended that the first level be the domain suffix "com" and the second level be the vendor/individual name. More levels are also accepted.	String	No
vendor	Description of the application vendor. The value is a string with a maximum of 255 bytes.	String	Yes (initial value: left empty)
version	Version of the application. For details, see Table 3.	Object	No
apiVersion	OpenHarmony API version on which the application depends. For details, see Table 4.	Object	Yes (initial value: left empty)
singleton	Whether to enable singleton mode for the application. This attribute applies only to system applications and does not take effect for third-party applications. If this attribute is set to true, the application always runs in singleton mode, even in multi-user scenarios. This attribute is supported since API version 8.	Boolean	Yes (initial value: false)
removable	Whether the application can be uninstalled. This attribute applies only to system applications and does not take effect for third-party applications. It is supported since API version 8.	Boolean	Yes (initial value: true)

Table 3 Internal structure of version

Attribute	Description	Data Type	Initial Value Allowed
name	Application version number visible to users. The value can be customized and cannot exceed 127 bytes. The customization rules are as follows: API 5 and earlier versions: A three-segment version number is recommended, for example, A.B.C (also compatible with A.B). In the version number, A, B, and C are integers ranging from 0 to 999. Other formats are not supported. A indicates the major version number. B indicates the minor version number. C indicates the patch version number. API 6 and later versions: A four-segment version number is recommended, for example, A.B.C.D. In the version number, A, B, and C are integers ranging from 0 to 99, and D is an integer ranging from 0 to 999. A indicates the major version number. B indicates the minor version number. C indicates the feature version number. D indicates the patch version number.	Number	No
code	Application version number used only for application management by OpenHarmony. This version number is not visible to users of the application. The value rules are as follows: API 5 and earlier versions: It is a non-negative integer less than 32 bits in binary mode, converted from the value of version.name as follows: The conversion rules are as follows: Value of code = A * 1,000,000 + B * 1,000 + C. For example, if the value of version.name is 2.2.1, the value of code is 2002001. API 6 and later versions: The value of code is not associated with the value of version.name and can be customized. The value is a non-negative integer ranging from 2 to 31. Note that the value must be updated each time the application version is updated. The value for a later version must be greater than that for an earlier version.	Number	No
minCompatibleVersionCode	Earliest version compatible with the application. It is used in the cross-device scenario to check whether the application is compatible with a specific version on other devices. The value rules are the same as those of version.code.	Number	No (initial value: code attribute value)
