[BUG] PaymentSheet: keyboard dismisses on every card field auto-advance (Android 16)

[andrey2ag]

Summary

In PaymentSheet's card form, when a field is completed (16th card number digit, 4th expiry digit, 3rd CVC digit), focus correctly auto-advances to the next field, but the soft keyboard dismisses. The user has to tap every field to bring the keyboard back. iOS PaymentSheet auto-advances with the keyboard staying open.
We traced it with ImeTracker and a debugger. On field completion, Compose's legacy text input pipeline issues an explicit IME hide during the focus handoff:

InsetsController.hide
← SoftwareKeyboardControllerCompat.hide
← androidx.compose.ui.text.input.InputMethodManagerImpl.hideSoftInput
← TextInputServiceAndroid.setKeyboardVisibleImmediately
← TextInputServiceAndroid.processInputCommands

ImeTracker shows the sequence: client hide (HIDE_SOFT_INPUT_BY_INSETS_API), then the next field's ATTACH_NEW_INPUT show request, which is cancelled by a system hide (IME_REQUESTED_CHANGED_LISTENER). The hide wins, so the keyboard stays down.

The old field's input session stops in one frame and the next field's session starts in a later frame, so the intermediate hide actually runs. A minimal Compose app with the same pattern (NumberPassword fields + LaunchedEffect + moveFocus(Next) on completion) does not reproduce this — the stop/start coalesce in one frame and the keyboard stays open. So it's specific to the PaymentSheet form structure, not generic Compose.

Code to reproduce

paymentSheet.presentWithIntentConfiguration(
     intentConfiguration = PaymentSheet.IntentConfiguration(
         mode = PaymentSheet.IntentConfiguration.Mode.Setup(setupFutureUse = OnSession),
     ),
     configuration = PaymentSheet.Configuration.Builder("Example").build(),
 )
 1. Open the card form, tap Card number
 2. Type 4242 4242 4242 4242
 3. Focus moves to MM/YY, keyboard dismisses
 4. Same happens on completing MM/YY and CVC

I've been trying to repro this week, but haven't managed to do so on my Pixel 10 or the emulator you mentioned. Can you share more info about your environment and the other dependencies you're bringing in? (Specifically your version of Jetpack Compose and associated libraries!)
