Question

I am trying to make a Browser on Android and it extends WebView class.

There are two functions of my Browser:

1.Could play html5 video tag.
(I enable HardwareAccelerate and setWebChromeClient and it works fine on Android 4.0.)

2.The Browser must have a transparent Background.
(On Android 4.0, just setBackground(0) is not enough. I must also use setLayerType(LAYER_TYPE_SOFTWARE, null).)

But when I use setLayerType(LAYER_TYPE_SOFTWARE, null), the video tag can not paly. And that means setLayerType(LAYER_TYPE_SOFTWARE, null) disable HardwareAccerlarate so the video tag can not work.

So Can I consider that On Android 4.0, the two function is conflicting?Is there any workaround?

//set BackGroundColor
setBackgroundColor(Color.argb(0, 0, 0, 0));
if(android.os.Build.VERSION.SDK_INT>=11){
    setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);
}

//set WebChromeClient
setWebChromeClient(new WebChromeClient());

Answer 1

I have to say that, seems no guys met this issue as me.
So I think the two functions mentioned in my question is really conflicting.
