title: After change some code, should i restart the Android Emulator?
body: <p>I have opened the Android Emulator for my first set of code change. Then later i change some of my code. Should i want to close the emulator and relaunch (re-run) the code to reflect my new changes? or else simply pressing run key in eclipse will reflect the changes?</p>
  
  <p>Please clarify. </p>
  
  <p>PS : Till now, i wont close and relaunch the emulator for every code change. But today i faced the error in console like "Application already running, uninstall the application and try". That's why i have doubt on this.</p>
