I need to put up a context menu in the app when the user selects text
in the WebView. The options in that context menu depend on yes or no
answers I pull from javascript. The content is local content that is
set up to deliver these answers.
if(webView.needsOption1())
// Add option1 to context menu.
I find it strange that this is such a difficult task in Android. I
feel like I'm almost there, I'm just missing something thread related
that causing my web view to lock.
