java Android - how can I make WebView transparent for android 2.x?

I need a WebView to be transparent, but can't find solution

I've found only 

webView.setBackgroundColor(0x00000000);
webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);

, but this is only for Honeycomb and older and I need my App to work on 2.x also. None of the solutions I've found on stackoverflow are working- webView is still white.

Can anyone tell me what's working for sure for pre-Honeycomb versions?

maybe I should change something in html as well?

I had written a helper method to do that and it seems to work the majority of the time, setting the background color to transparent for all versions and changing the layer type where available...

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@SuppressLint("NewApi")
public static void clearWebViewBackground (final WebView webView) {
    webView.setBackgroundColor(0x00FFFFFF);
    webView.setWebViewClient(new myWebViewClient());
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
        webView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);
    }
}

This worked for me : myWebView.setBackgroundColor(Color.TRANSPARENT);

OR add as part of html here is my code snip :

String css = "<head><style >* {word-wrap: break-word;margin:0;padding:0;font-size:15px; text-align:justify;font-family: Arial, Helvetica, sans-serif}</style></head>";

myWebView.loadData(css, "text/html", null);
myWebView.setBackgroundColor(Color.TRANSPARENT);
