La storia

COME APK
È NATO.

2008

2018

2021

2026

APK — Android Package Kit — shipped with Android 1.0 in September 2008 as the installation format for Android apps. Technically an APK is a ZIP archive with a specific layout: AndroidManifest.xml describes permissions and components, classes.dex contains the Dalvik bytecode, resources.arsc holds compiled resources, and a META-INF directory holds the digital signature.

For 12 years every Android app shipped as an APK. Then Google introduced Android App Bundles (.aab) in 2018 and in August 2021 made AAB mandatory for new apps on Google Play — though direct APK distribution (side-loading, F-Droid, corporate MDM) remains fully supported. In 2026 most power-user and developer audiences still download apps as APKs; everyday users get per-device-optimized splits generated from AABs.

CURIOSITÀ E
ANEDDOTI.

An APK is literally a ZIP archive — rename to .zip and you can browse the DEX bytecode, resources, and manifest inside.

Every APK must be cryptographically signed — Android refuses to install unsigned apps since Android 1.0.

Google Play switched to requiring AAB (App Bundle) uploads for new apps in 2021, but APKs remain valid for distribution everywhere else.

F-Droid, the open-source Android app store, only hosts APKs — its entire ecosystem depends on the format staying alive.

Android's DEX format — Dalvik Executable, inside classes.dex in every APK — was designed for the Dalvik VM and later ART runtime.

PUNTI DI FORZA E
LIMITAZIONI.

Punti di forza

Universal Android distribution since 2008.
Self-contained: one file, installs anywhere.
Cryptographically signed — tamper-evident.
Supports side-loading, corporate distribution, and alternative stores.
ZIP structure makes inspection trivial.

Limitazioni

Google Play prefers AAB for new submissions since 2021.
File sizes can be large — game APKs often exceed 150 MB.
Without code obfuscation, decompilation is straightforward.
Multi-architecture APKs bloat file size for users.

Dimensioni e pesi tipici

Simple utility app

2-15 MB

Typical consumer app

30-80 MB

Modern 3D game

150 MB - 2 GB
