Android WebView style background-color:transparent ignored on android 2.2

I'm struggling to create a WebView with transparent background.

webView.setBackgroundColor(0x00FFFFFF);
webView.setBackgroundDrawable(myDrawable);

Then I load a html page with

<body style="background-color:transparent;" ...

The background color of the WebView is transparent but as soon as the page is loaded, it's overwritten by a black background from the html page. This only happens on android 2.2, it works on android 2.1.

So is there something to add in the html page code to make it really transparent ?

Solution 1:

This worked for me,

mWebView.setBackgroundColor(Color.TRANSPARENT);

Solution 2:

At the bottom of this earlier mentioned issue there is an solution. It's a combination of 2 solutions.

webView.setBackgroundColor(Color.TRANSPARENT);
webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);

When adding this code to the WebViewer after loading the url, it works (API 11+).

It even works when hardeware acceleration is ON
