Technical Details
An APK file is essentially a ZIP archive that contains compiled code (in Dalvik executable format), resources, assets, certificates, and a manifest file (AndroidManifest.xml). The manifest file describes the essential information about the app, such as its name, version, permissions, and required hardware features. The compiled code is usually in DEX format, which is optimized for the Android runtime environment.
