TOPIC:

I have found examples in CodeOcean for js_WebWidgetsGUI. 

Folder - CodeOcean\js_Pas2JavaScript\js_WebWidgetsGUI.

I have build in CT 8.7 this project CodeOcean\js_Pas2JavaScript\js_WebWidgetsGUI\20_tests.

I used testCanvas.html from the folder "20_tests" and this site htmltopdf.live/html-to-apk-converter/

to create project of Android App.

After that I have added the folder "assets" to the project.
And copied the files "testcanvas.js" and "testcanvas.js.map" into it.

I renamed testCanvas.html into index.htlm because Java-launcher named MainActivity.java had this code
webView.loadUrl("file:///android_asset/index.html")

If you want you can change Url to "testcanvas.html".

Then I have build the project with sdk in Android studio.

The instructions are given in file Readme.md 

Check this file in downloaded zip-archive from the site htmltopdf.live/html-to-apk-converter/ .


After that I have build another the project - CodeOcean\js_Pas2JavaScript\js_WebWidgetsGUI\10_testcontrols

And did the same steps I have mentioned above to create and build Android app.


Both Android applications successfully started on smartphone with Android 12.


More information - on screenshots attached.


On tab jsGUI Base in CT there are many ready to use components .

I think this is quite enough for start in creating Android app with GUI.
