title: Android emulator is not working properly. Why?
body: <p>I have been using Android studio and emulator for the past 2 months now, and it was working very well and fast.</p>
  
  <p>Now, once I shut down my laptop while android studio running, I don't know if this is the reason that caused this.</p>
  
  <p>Now, Android monitor goes crazy when I run my application, it doesn't happen when I do it in my device, only in AVD.</p>
  
  <p>P.S.: I have tried rebuilding, invalidate cache and restart, re-install AVD, re-install android studio (complete uninstallation with SDK) but the problem still persists. (Here's the log (not full logcat) and device boots like after 2 mins, earlier it used to be like 10 secs and then there's black screen)</p>
