title: How can I install an old emulator image?
body: <p>My app is affected by a bug that is only present on certain builds of Android. Unfortunately, the bug is missing from the emulator images that are currently available through SDK Manager.</p>
  <p>For example, I have revision 8 of the Android 10 emulator image installed, but the bug might only be present on revision 4.</p>
  <p>How can I install an older revision of one of the emulator images, such as revision 4 of the Android 10 image?</p>
