WebView "flashing" with white background if hardware acceleration is enabled (Android 3.0+)

I found the most effective fix for this, first mentioned here, was to set a transparent background color after the layout has been inflated:

webView.setBackgroundColor(Color.argb(1, 0, 0, 0));

Yes, it's a total hack, but it's the only solution I've found to work well without disabling hardware acceleration.

Note that this does not work through setting the background in XML.

This has been resolved in Jellybean, although some users have reported seeing this in KitKat. Check that you have not disabled hardware acceleration, and if the problem indeed disappears, you will probably want to wrap that code in a conditional statement to only target older devices:

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {    webView.setBackgroundColor(Color.argb(1, 0, 0, 0));}

I have enabled the hardware acceleration for the application and have disabled it for the activity. Additionally I set the background to null, as mentioned above. It works for me now.

Another approach (untested): set the layer type to software rendering and set the background to Color.TRANSPARENT (or 0): webview.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

Had this problem on Android 4.4.4 and none of the other solutions here worked. I was messing around with onPageFinished() anyway, so might as well try somthing that should be bullet proof:

I put this in the onCreateView() of the fragment that hosts the WebView:

    webView = (WebView) v.findViewById(R.id.webView);    webView.setVisibility(View.INVISIBLE);    webView.setBackgroundColor(Color.argb(1, 0, 0, 0));             webView.setWebViewClient( new WebViewClient(){        @Override        public void onPageFinished(WebView view, String url) {            view.setVisibility(View.VISIBLE);            super.onPageFinished(view, url);        }    });

The idea is simply to hide the WebView until the first page has loaded. However, it still gave me a small flash of white until I also added the solution provided by Paul Lammertsma, webView.setBackgroundColor(Color.argb(1, 0, 0, 0));
