Application Profile Overview (FA Model)
Each application project must add configuration files in the project's code directory. These configuration files will provide basic information describing the application to the HarmonyOS compilation tool, HarmonyOS operating system and application market.
The application configuration file must declare the following:
- The application's package name, application developer, version number and other basic configuration information of the application are required to be set under the app field.
- Basic information about the components of the application, including all capabilities, device types, component types, and the syntax type used by the current component.
- Configuration information of the application on a specific device. This information will affect the specific functions of the application on the device.
During the application development process of the FA model, the application package structure needs to be declared in the config.json configuration file.
The internal structure of the configuration file
config.json consists of three parts: app, deviceConfig and module, all of which are indispensable.
| Property name | meaning | type of data | Whether it can be defaulted |
|---|---|---|---|
| app | Identifies the global configuration information of the application. The app configurations of different HAPs for the same application must be consistent. | object | Cannot be defaulted. |
| deviceConfig | Identifies the configuration information applied to a specific device. | object | Cannot be defaulted. |
| module | Identifies the configuration information of HAP. The configuration under this label only takes effect for the current HAP. | object | Cannot be defaulted. |
config.json example:
{ "app": { "vendor": "example", "bundleName": "com.example.demo", "version": { "code": 1000000, "name": "1.0.0" } }, "deviceConfig": { }, "module": { "mainAbility": ".MainAbility_entry", "deviceType": [ "tablet" ], "commonEvents": [ { "name": ".MainAbility", "permission": "ohos.permission.GET_BUNDLE_INFO", "data": [ "com.example.demo", "100" ], "events": [ "install", "update" ] } ], "abilities": [ { "skills": [ { "entities": [ "entity.system.home" ], "actions": [ "action.system.home" ] } ], "orientation": "unspecified", "visible": true, "srcPath": "MainAbility_entry", "name": ".MainAbility_entry", "srcLanguage": "ets", "icon": "$media:icon", // $string:MainAbility_entry_desc为资源索引 "description": "$string:MainAbility_entry_desc", "formsEnabled": false, // $string:MainAbility_entry_label为资源索引 "label": "$string:MainAbility_entry_label", "type": "page", "launchType": "standard" } ], "distro": { "moduleType": "entry", "installationFree": false, "deliveryWithInstall": true, "moduleName": "myapplication" }, "package": "com.example.myapplication", "srcPath": "", "name": ".myapplication", "js": [ { "mode": { "syntax": "ets", "type": "pageAbility" }, "pages": [ "pages/index" ], "name": ".MainAbility_entry", "window": { "designWidth": 720, "autoDesignWidth": false } } ] }}

Here is a "Hongmeng Zero Basics Beginner's Study Guide", hoping to provide some help to those who want to learn Hongmeng but have no direction. This document is suitable for beginners in HarmonyOS application development (due to the excessive content of the document, in order to avoid affecting everyone’s reading experience, only part of the content is shown in screenshots. There is a free way to obtain the detailed full version at the end of the article!)

3. Resource classification and access
During application development, resources such as colors, fonts, spacing, and pictures are often used. The values of these resources may be different in different devices or configurations.
- Resource classification and access

- Resource directory
- Resource group directory
- Create resource directories and resource files
- Create resource directories and resource files
- Create resource directory
- Create resource files
- resource access
- Application resources
- system resource
- Resource matching
4. Learn ArkTs language
ArkTS is the preferred main application development language of HarmonyOS. ArkTS has further expanded on the TypeScript (referred to as TS) ecosystem around application development. It inherits all the features of TS and is a superset of TS. Therefore, before learning the ArkTS language, it is recommended that developers have TS language development capabilities.
