Ionic-framework: bug: ionKeyboardDidShow does not fire on android/chrome

[jmannau]

Bug Report

Ionic version:


[ ] 4.x
[x] 5.x

Current behavior:

On iOS, the ionKeyboardDidShow & ionKeyboardDidHide events are fired correctly. This does not happen on Android devices. I have tested this on the following devices

• Real device with Android 8.0.0 with Chrome 83.0.4103.106
• Android Emulator Android 9.0 with Chrome 69.0.3497. 100

Expected behavior:

For compatible versions of Chrome & Safari, ionKeyboardDidShow & ionKeyboardDidHide events should fire.

Steps to reproduce:

1. Create an Android 9 Emulator
2. On the emulator, open https://jmannau.github.io/ionic-keyboard-event-test/home
3. Click in the input box. The Keyboard Is Visible field should show true. If no events are fired then Keyboard is Visible stays false

Related code:

I have created a simple repository to test the events on different devices https://github.com/jmannau/ionic-keyboard-event-test you can goto this link and test the events https://jmannau.github.io/ionic-keyboard-event-test/home

Other information:

For the devices I have tested, the problems appears to be related to layoutViewportDidChange.

This returns true and prevents the detection of keyboard showing in keyboardDidOpen

Thanks! It looks like when the keyboard opens in Google Chrome on Android, the entire view is resized (both layout and virtual viewports), whereas Safari on iOS only resizes the virtual viewport. Our keyboard utility had too much of a dependence on the layout viewport not changing, which caused this bug.

Can you try the following dev build, and let me know if it resolves the issue?

npm i @ionic/[email protected]

I've updated the test app and tested it on our devices and it looks good :D.

Thanks very much for such a quick response!
