Android 17 will introduce a system for "Registered App Stores," allowing third-party app stores that meet Google's certification standards to benefit from a unified installation interface. Users will see a straightforward prompt when installing a certified app store, with clear explanations and links to essential information. Certified stores will automatically gain permission to install and manage other applications, simplifying the installation process and improving user experience. The initiative will reduce barriers imposed by OEMs, ensuring a consistent installation process across devices. Security measures will remain intact, with Google Play Protect continuing to scan apps from all sources. The new system will be integrated into Android 17, with potential support in the initial release or by Android 17 QPR2. Competing app stores will not be able to promote themselves through Google Play, but users can still access certain titles directly through their respective apps.
