Incriminated API

// In Android
Keyboard.addListener('keyboardDidShow', e => {
   // On OnePlus 7, and Pixel 3XL (simulator) this value is underestimated by exactly StatusBar.currentHeight.
    e.endCoordinates.height
})

Prerequisites

In AndroidManifest.xml, set android:windowSoftInputMode="adjustPan".

Visual tests

The black horizontal bar should be the same width (40dp) as the red bar, in a container with a bottom padding of the keyboard's height. This component mimics KeyboardAvoidingView with behavior padding set. The height of keyboard should be the same as the height of the red bar. The issue has been reproduced with GBoard, SwiftKey...

Remarks: I would have imagined that the view height would equal keyboard height + keyboard Y. But that is only true ... on OnePlus7, which is the problematic device!

Steps To Reproduce

1. Open the reproduction demo in a Pixel 3XL emulator with Android 10+.
2. Observe that KeyboardAvoidingView with behavior padding doesn't add enough padding.

Describe what you expected to happen: The padding should match keyboard's real height.

Observations

• StatusBar.currentHeight is substituted to the keyboard layout end frame height.
• StatusBar.currentHeight is also substituted from keyboard layout end frame screenY
