每個應(yīng)用項目必須在項目的代碼目錄下加入配置文件，這些配置文件會向HarmonyOS的編譯工具、HarmonyOS操作系統(tǒng)和應(yīng)用市場提供描述應(yīng)用的基本信息。

應(yīng)用配置文件需申明以下內(nèi)容：

應(yīng)用的軟件包名稱，應(yīng)用的開發(fā)廠商，版本號等應(yīng)用的基本配置信息，這些信息被要求設(shè)置在app這個字段下。

應(yīng)用的組件的基本信息，包括所有的Ability，設(shè)備類型，組件的類型以及當前組件所使用的語法類型。

應(yīng)用在具體設(shè)備上的配置信息，這些信息會影響應(yīng)用在設(shè)備上的具體功能。

在FA模型的應(yīng)用開發(fā)過程中，需要在config.json配置文件中對應(yīng)用的包結(jié)構(gòu)進行聲明。
