Definition and structure of an APK file
An APK file is essentially a ZIP file that contains four main components:
AndroidManifest.xml: This is a file that defines the app's identity, features, permissions, activities, services, etc. It also specifies the minimum Android version required to run the app.
classes.dex: This is a file that contains the compiled Java code of the app. It is converted into a format that can be executed by the Android Runtime (ART) or Dalvik Virtual Machine (DVM).
resources.arsc: This is a file that contains the compiled resources of the app, such as strings, images, layouts, etc. It is used to provide different versions of the resources for different languages, screen sizes, orientations, etc.
res: This is a folder that contains the raw resources of the app, such as images, sounds, fonts, etc. It is used by the resources.arsc file to access the resources.
An APK file can also contain other optional components, such as:
META-INF: This is a folder that contains metadata and signatures of the app. It is used to verify the authenticity and integrity of the app.
lib: This is a folder that contains native libraries of the app. These are files written in C or C++ that can be executed by the device's processor directly.
assets: This is a folder that contains additional files of the app that are not compiled into resources.arsc or classes.dex. These can be any type of files, such as HTML, CSS, JavaScript, etc.
