Description

Description

When switching between different keyboard types on Android, Keyboard.addListener events and Keyboard.metrics()?.height return the height of the previous keyboard instead of the current one. This issue occurs consistently when the previous and current keyboards have different heights (e.g., switching from numeric keyboard to password keyboard, or from system security keyboard to regular keyboard). The problem affects both event callback heights and the static Keyboard.metrics()?.height value. The issue resolves itself on the next keyboard opening, but can be stably reproduced by switching between different keyboard types.

Steps to reproduce

Steps to reproduce the behavior:

  1. Open an app with text inputs on Android device
  2. Focus on a text input with keyboardType: 'numeric'
  3. Note the keyboard height (e.g., 300px)
  4. Switch to another text input with keyboardType: 'visible-password'
  5. Observe that both Keyboard.addListener events and Keyboard.metrics()?.height return the previous keyboard's height (300px) instead of the current keyboard's height
  6. Close and reopen the keyboard - the issue resolves and correct height is returned

Research direction

Start by reproducing the issue on Android using inputs with numeric and visible-password keyboard types, then inspect the implementation behind Keyboard.addListener and Keyboard.metrics(). Verify the reported height when switching keyboards and when reopening the keyboard; done means both event callbacks and metrics report the current keyboard height.
