Google confirmed to Android Authority that it is committed to publishing Android’s source code, so this change doesn’t mean that Android is becoming closed-source. The company will continue to publish the source code for new Android releases, so when Google releases Android 16 later this year, we’ll get the source code for the update. In addition, Google will continue to publish the source code for Android’s Linux kernel fork, as it is licensed under GPLv2, which mandates source code releases, and is separate from AOSP.
What will change is the frequency of public source code releases for specific Android components. Some components like the build system, update engine, Bluetooth stack, Virtualization framework, and SELinux configuration are currently AOSP-first, meaning they’re developed fully in public. Most Android components like the core OS framework are primarily developed internally, although some features, such as the unlocked-only storage area API, are still developed within AOSP.
