title: Android x86-based system image not found in SDK rev 18 update
body: <p>Yesterday I've updated Android SDK to rev 18, but there's only ARM EABI v7a system image for API level 14 &amp; 15, while in <a href="http://developer.android.com/guide/developing/devices/emulator.html#accel-vm" rel="nofollow">this tutorial</a> they say I could use x86-based system image for better &amp; smoother performance of emulator. I've check in sdk-folder\tool\ and "emulator-86.exe" also exists, but no x86 AVD created to run with this. I also install HAXM and it works fine in my machine. In GUI AVD creation, the CPU/ABI dropdown box also be disabled for every API level.</p>
  
  <p>So where I could find and use x86 based system image for my Android SDK? Any help is appreciated. Thanks</p>
