What is config apk app?

Config APK app is an Android application package file that contains configuration data for an application. It is used to customize the behavior of an application before installation on a device. The configuration data can include settings such as default language, server addresses, security keys, feature activation, branding elements, and other preferences.

The Config APK app works by overriding the default settings of the base app and applying custom settings during installation or first launch. It is often used by developers to create multiple versions of an app with different configurations for different customers or regions. Config APKs are also used by system administrators to deploy Android apps with custom settings to devices in an organization.

To create a Config APK app, the developer needs to use Android Studio or other build tools to build an APK file of the app with the default settings. The developer then needs to create a separate Config APK file with the custom configuration data. The Config APK is then packaged into the main APK as an extra package, which is installed along with the base app when it is installed on an Android device.
