title: Android: How to stop emulation
body: <p>I'm coming from Visual studio and C# and am new to Android (and eclipse) so quite ignorant of basic functionality.
  I've written a short app and ran it under the emulator. No problems.
  Now I've made some changes and want to test them. In VS I'd stop the application debug run before making code changes, and after the code changes run again.</p>
  
  <p>I can't find the 'stop' debug button in eclipse. How do I run my app after I've made changes?</p>
