title: Casting to String by parentheses gives crash on Android
body: <p>I know how to get a String from a TextView with toString(), but i would like to understand why if i cast the TextView's text to String by parentheses, it leads Android to crash at runtime ?</p>
  
  <p>e.g "<code>String text = (String)((TextView)findViewById(R.id.myTextViewId)).getText();"</code></p>
