The `content` param here is the same as `data` in `WebView.loadData` right? http://developer.android.com/reference/android/webkit/WebView.html#loadData(java.lang.String, java.lang.String, java.lang.String) . 
And in your comment, you say it could be empty, i am suggesting add an overloading api so that it becomes an optional params. (As Java doesn't provide way to give default value for params)
