I have a simple webview client that gets the content from a url and
loads it into the WebView. When the activity starts and the first
data is loaded into the WebView it works beautifully. I can click the
href of the image returned in the url data and the WebView launches
the browser just fine. However, if I then update the contents of the
WebView with another call to loadData, the WebView displays the new
data but you cannot click on anything in the WebView...
I do not see any logs like
Starting activity: Intent { action=android.intent.action.VIEW
categories={android.intent.category.BROWSABLE}
in the log viewer...
If I relaunch my activity, it again works the first time but not for
additional content. Is there something else I am supposed to do to
get the WebView to support the clicking of hrefs in the data that was
loaded?
thanks, Mark
