title: Android app always crashing
body: <p>I'm new at programming for android so i've started to follow tutorials on the internet, very simple stuff but when I compiled it in order to run on the emulator it always says: "Unfortunately your program has stopped" on my device emulator (nexus 4) so i thought I had an error on my java code.</p>
  
  <p>So I created a brand new project unmodified with the usual "hello world" so it should work, but when I'm going to run it appears the same thing. "Unfortunately your program has stopped".
  Here's what shows on my console.</p>
  
  <p>Maybe it has something to do with the version of the API i'm using?</p>
