Android and Google Play form a vast ecosystem with billions of users and millions of apps, and keeping it safe is a top priority. To combat bad actors, Google invests in AI-powered threat detection, stronger privacy policies, and developer tools. In 2024, Google prevented 2.36 million policy-violating apps from being published and banned 158,000 bad developer accounts. Advanced AI helps identify malware, detect bad apps, and streamline review processes for compliant developers. Google works with developers to reduce unnecessary access to sensitive data and promotes transparency about data handling. The Play Integrity API helps developers prevent abuse like fraud, bots, and data theft. Google Play Protect provides multi-layered protections against bad apps, including rigorous review, user reviews, and built-in security protection. Google Play Protect scans over 200 billion apps daily and identified 13 million new malicious apps in 2024. New improvements to Google Play Protect include reminder notifications, protection against social engineering attacks, and automatic revocation of app permissions for potentially harmful apps. Google also collaborates with governments, developers, and industry peers to advance app security standards and protect the entire ecosystem.
