Starting with Android version 8, third party applications may register as Autofill services for recognized fields including usernames and passwords. Previously, the only way for RoboForm to fill those fields (which is still supported) was via the Android accessibility API.
Enabling RoboForm as an Autofill service in Android 8 or later
In the RoboForm app click the 3 dots on the top right -> Settings -> App integration -> Autofill in applications
The RoboForm Autofill service will capture usernames and passwords entered into Android apps. However, RoboForm web Logins or those created via the Accessibility object will not populate during Autofill. For the time being, the RoboForm Autofill service needs to capture each Login anew.
We are currently investigating ways to better integrate the Autofill service with existing RoboForm Logins to avoid this extra step.
