Google announced its Android developer verification program last year to enhance the safety of app sideloading for users. Recently, the company updated that Android users will need to wait 24 hours before sideloading apps from unverified developers. Now, Google has shared the timeline for these upcoming sideloading changes.
Beginning this month, Google will implement a new system service that will be automatically installed on most Android devices. This service will also be used to verify developer registration later this year.

In July, Google plans to launch the Android Developer ID Status API globally, alongside providing early access to the Android Developer Console API. An early access option for limited distribution accounts on the Android Developer Console will also be introduced. This type of account is designed for students, hobbyists, and learners, permitting app sharing with up to 20 devices without requiring a government-issued ID or fee.
In August, Google will officially launch the limited distribution accounts and the updated Android Developer Console API. Additionally, an advanced flow for power users to install apps from unverified developers will be made available.
On September 30, new developer verification protections will begin, initially affecting Brazil, Indonesia, Singapore, and Thailand. Registration will be necessary for participating app stores, including Google's Play Store, Honor App Market, Oppo App Market, Galaxy Store, V-Appstore, Palm Store, and GetApps.
Users will still have the option to sideload unregistered apps using Android Debug Bridge (ADB) or the advanced flow.
Timeline shared by Google for its new app sideloading changes coming to Android
By 2027, Google plans to expand the Android developer verification requirement globally, incorporating feedback from partners, users, and the developer community.
For developers distributing apps in Brazil, Indonesia, Singapore, or Thailand using the aforementioned app stores, verification must be completed by September.
