What is config apk?

A config APK, also known as a configuration APK, is a file used in Android applications to store settings or configuration data separate from the main APK file. This allows developers to make changes to the app's settings without having to release a new version of the app.

Config APKs are typically used for things like feature flags, AB testing, remote configuration settings, and other dynamic content that may need to be updated frequently. By separating this data into a separate APK file, developers can make changes to the app's configuration without needing to push out a new update to users.

Config APKs can be created using tools like bundletool and can be distributed alongside the main APK file through the Google Play Store or other distribution channels.

Overall, config APKs help developers to manage and update app settings more efficiently, without requiring users to download a new version of the app every time a change is made.
