Android WebView renders blank/white, view doesn't update on css changes or HTML changes, animations are choppy

Question

When ever I make a css class change, the changes don\'t always appear. This appears to happen when I have a touch event that adds something like a down class name to a butto

Answer 1

You should enable hardware by modifying your manifest:

And in your activity onResume()

webView.postDelayed(() -> {
    if (!isFinishing() && webView != null) {
        webView.setLayerType(View.LAYER_TYPE_NONE, null);
    }
}, 1000);

And in your onPause()

webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
