title: How to stop emulated app from running? (Android Studio, 64-bit Win7 SP1)
body: <p><a href="http://developer.android.com/training/basics/firstapp/running-app.html#Emulator" rel="nofollow">Running Your App -> Run on the Emulator</a> clearly explains how to RUN an app from within Android Studio by launching the emulator.</p>
  
  <p>My question is - 
  Once I've done that: "How should I STOP the emulated app from running?"</p>
  
  <p>Thought #1 - Use the "Run -> Stop (Ctrl + F2)" option on Android Studio's menu. But, when running my simple Hello-World-type application, that option is disabled.
  Accordingly, Ctrl+F2 has no effect.</p>
  
  <p>Thought #2 - Close the emulator window, by right-clicking the emulator's icon in my task bar, and selecting "Close window."
  That closed the application all right, but then it seemed to leave things in a strange state.
  -- When I tried to run the application again, it gave an error and I had to recreate the project.
  That happened repeatably.</p>
  
  <p>Thought #3 - Try shutting down the (emulated) Android device.
  I tried that on Saturday evening: I held down the (emulated) Power button. Clicked the option in the "Device options" window.
  It's now Monday morning, and it still says that it's "Shutting down...".</p>
  
  <p>So, "How should I stop the emulated app from running?"</p>
  
  <p>Thank you for any suggestions/help you can provide.</p>

  <p>I now see that I had asked the wrong question.
  I should have asked how to stop a running emulator.</p>
  
  <p>Although I had been able to do so by right-clicking the emulator's entry in the task bar, and selecting "Close window", that had SEEMED to cause some problems.
  ["The selected device is incompatible" was displayed in the "Device Chooser" dialog.]
  So, I thought that was the wrong way to do it.</p>
  
  <p>Since then, though, I think I've figured out that something else was causing my problems:</p>
  
  <ol>
  <li><p>I had an Android emulator process (emulator-arm.ese *32) which
  hadn't terminated properly.</p></li>
  <li><p>When I selected another device, I hadn't
  given the (slow) Android emulator enough time to clear the "The
  selected device is incompatible" error(s).</p></li>
  </ol>
  
  <p>The problem process stayed in Windows' Task Manager after I shut down Android Studio, and Task Manager's  failed to kill it.
  So I rebooted my PC, and now everything seems to work OK.</p>
