multi-touch / pinch-zoom troubles on android

[ray007]

I have already posted the problem at NativeScript/android#1827, but maybe someone here has an idea on what's going wrong.

Which platform(s) does your issue occur on?

• Android
• tested on Android 13+
• devices, all phones
• tested with versions 1.4.11 and 1.5.0

Please, provide the following version numbers that your issue occurs with:

• CLI: 8.8.2
• Cross-platform modules: 8.8.2
• Runtime(s): android 8.8.5

Please, tell us how to recreate the issue in as much detail as possible.

Even the simplest project with just a single webview fails to work with multi-touch in the webview.

Is there any code involved?

I created a preview app at https://stackblitz.com/edit/nativescript-stackblitz-templates-fblndg?file=app%2Fcomponents%2FHome.vue, but the webview does not show any content in NS-preview.
Generating a simple app with only a webview showing a pinch-zoom test https://humphryscomputing.com/test.pinch.html or https://coderundebug.com/blog/pinch-zoom-move-rotate-image/ should suffice.

Info Update: although pinch-zoom broke when only updating @nativescript/android, a simple test page with the standard WebView still seems to do pinch-zoom fine, while using AWebView (vue variant) does not.

@ray007 Have you tested with vue3? In my case this problem was observed when using vue2, but disappeared in vue3
