title: Does the parsing of xml files in android happen at runtime or compile time?
body: <p>I am far from an expert when it comes to understanding the minutia of code compilation. But I am learning some android development, and I noticed how layouts and other things are essentially parsed out of xml. I was wondering if this parsing happens at compile time or at runtime? If it is at runtime, it seems like there might be some overhead associated with parsing out a very complex layout. </p>
  
  <p>Hope that this question isn't too vague or doesn't make sense.</p>
