Which Android version introduced the autofill framework?

Android 8.0 introduced the autofill framework.

Released in 2017 under the codename Oreo, Android 8.0 added a system framework that lets apps request saved information for fields such as usernames, passwords, addresses, and payment details. The framework coordinates between an app displaying form fields, the Android system, and an autofill service—often a password manager or another credential provider.

This was more than a visual convenience: it created a standardized way for services to fill fields across different apps. Users still needed an enabled autofill provider, so the feature’s availability depended partly on device settings and installed services. Android 8.0 corresponds to API level 26; Android 8.1 is API level 27 and refined the Oreo release but did not introduce the framework itself.

A common mix-up is confusing Android’s autofill framework with browser form autofill or older keyboard suggestions. Those mechanisms existed earlier, but Android’s platform-wide framework began with Oreo. Later Android releases connected autofill more closely with credential managers and passkeys.
