title: Executing math equation in Android
body: <p>I need to be able to handle a math equation such as "(45+9)/8" in my app. I wanted to just eval it using JavaScript, but realized that I can't use javax.script in Android. So, I found WebView, but I'm having a bit of trouble using it. Most of the examples refer to using an external page with the JS code, or using "javascript: var return ...etc." I'd need to use the latter, but I've been having a bit of trouble with returning the variable to my app. </p>
  
  <p>Is it possible to have the JS eval it and then write the value to a hidden TextView?</p>
