From Android 4.4 the WebView is changed, and from Android 7.0 it is Chrome engine and not the WebView.
I see that my app is broken with newest Android versions because it uses many features of old WebView, it's targeted Android 3.1 and needs quirksmode, but quirksmode is not enough because some behaviour is unpredictable.
Now I am asking here if it is possible to compile my app so it carries the old WebView whatever the version of the Android OS.
