Google will implement a developer verification program for Android app installations starting next year, requiring all developers to be verified by Google to install apps on certified Android devices. This new requirement extends to third-party app developers and will apply to smartphones with pre-installed Google Services, excluding custom ROMs and certain Chinese devices. Developers distributing apps outside the Play Store must register on a new Android Developer Console for verification. Testing begins in October, with access for all developers by March 2026, and the rollout starts in Brazil, Indonesia, Singapore, and Thailand in September 2026, potentially expanding globally in 2027. Google cites internal data showing sideloaded apps pose a significantly higher risk of malware and aims to establish developer identity to reduce this risk. The changes may also be influenced by a recent antitrust ruling related to third-party app stores.
