title: Android: Is it good practice to store Views as global variable in class?
body: <p>I am new to Android, and have been reading that memory management is very important in those memory limited apps.</p>
  
  <p>I have read some where that activity's <code>findViewById()</code> is very expensive. So i'm wondering, if it is good practice to store the Views that you will be using as a global variable and reuse the object? Or is it better to run <code>findViewById()</code> everytime i need to use the view?</p>
  
  <p>Thanks,
  Kev</p>
