android – How to get transparent background of webView for 4.0 version-ThrowExceptions

Exception or error:

I am looking for a piece of code which is able to get a transparent background in a WebView for version 4.0 and above. My code is working fine with version 2.3 but it is getting a white background when I run it on version 4.0 and 4.2. I am providing my code which is working for version 2.3, but not in 4.0 and 4.2. Please help me. Thanks in advance…

In XML:

<WebView
    android:id="@+id/webView"
    android:layout_marginTop="6dp"
    android:layout_below="@+id/image"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:hardwareAccelerated ="true"        
    />

In activity file:

webView = (WebView) findViewById(R.id.webView);
backButton = (ImageView) findViewById(R.id.backButton);
webView.setBackgroundColor(0);                      
webView.loadUrl("file:///android_asset/Info.html");
webView.setBackgroundColor(Color.TRANSPARENT);  
/* this is used to make the background white after loading the file on screen. */
How to solve:

Try this:

webView.setBackgroundColor(0x00000000);

and remove android:hardwareAccelerated ="true"
as that is off-topic.

###

If webview is scrolable:

Add this to the Manifest:

android:hardwareAccelerated="false"

OR

Add the following to WebView in the layout:

android:background="@android:color/transparent" android:layerType="software"

Add the following to the parents scroll view:

android:layerType="software"

###

setBackgroundColor(0x00000000);
will make your webview transparent
