title: Emulator on Android Studio doesn't start after SDK tools update to 25.3.1
body: <p>After updating my Android SDK tools today to 25.3.1, the emulator won't run anymore.</p>
  
  <p>I can open the AVD Manager. When I hit "Play" on one of the emulators on the list, I see the bar below on Android Studio</p>

  <p>But then after the progress bar reaches the end, nothing happens.</p>
  
  <p>I see in the <a href="https://developer.android.com/studio/releases/sdk-tools.html#notes" rel="noreferrer">release notes</a> that the latest update brought changes to the emulator so I'm wondering if that's a bug or I'm missing something about that.</p>
  
  <p>I'm using Android Studio 2.3.</p>
  
  <p>Any ideas?</p>
