[Android] Autofill from saved credentials doesn't work

[TatsuUkraine]

Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

1. Create a form with username and password field
2. Try to use password manager such as Google Password Manager
3. Ensure that password usage requires biometric auth (not sure if it changes anything)
4. Click in Key icon on keyboard and select password

Device for testing

Google Pixel 7 pro, Android 14 (34)

Expected results

Form prepopulates with the selected username/password combination

Actual results

Input loses focus and nothing happens.

Form can be prepopulated only if login/password combination is selected from Keyboard quick actions and no biometric check is requested

Code sample

Code sample (very simple autofillgroup with 2 inputs)

           AutofillGroup(
              child: Column(
                children: [
                  TextField(
                    autofillHints: [AutofillHints.username],
                  ),
                  TextField(
                    autofillHints: [AutofillHints.password],
                  ),
                ],
              ),
            ),

Hi @TatsuUkraine. When you setup details, have you also set those up in the system "autofill service" settings and provide relevant information to the autofill service for it to work ?

[TatsuUkraine]

@dam-ease sorry, not sure that I understood the question( for this example I didn't do any native configuration for Android, basically this issue appears only when app looses focus either because of biometric auth or because you go into the password manager. If biometric auth is not requested, and you using password suggestions from the keyboard quick action - all works fine

[TatsuUkraine]

@dam-ease I already replied😅

[TatsuUkraine]

@dam-ease I added video to the description to better explain what is going on. On a video when screen goes black - it asks for biometric verification. On a video there are 3 attempts:

1. Using Key icon to go to the password manager.
2. Using quick action with biometric verification
3. Using quick action without biometric verification

Autofill works only when app doesn't go to background (3rd try)

[dam-ease]

I guess the time you replied and the time the label updated were the same.
We can reproduce the issue when clicking on Key icon > select saved account (without needing biometric verification). We tested with a Realme 6, Android 11.
Can you confirm again if you also can see the issue when removing biometric verification or not?

It seems biometric verification doesn't affect behavior a lot. If I disable biometric check for password usages only one difference is that there is no scenario 2 (from my prev comment). So it seems autofill just stops working when the app goes to background and the text field loses focus, either because of password manager bottom sheet or because of biometric check

Also, one note, I'm not entirely sure, since I didn't check this explicitly, but I think all was working in prev stable release
