title: AVD manager, unable to locate ADB
body: <p>just started android studio and set up an emulator. when I am in the virtual devices manager i have a nexus 6P api 30.
  when I hit the play button (the green triangle) it says &quot;unable to locate adb&quot; in a small pop-up. however the emulator still runs perfectly fine.</p>
  <p>my biggest problem is that when I try running my code in the emulator I have to select a device. however my emulator is not listed as any devices as it says &quot;no devices connected&quot;.</p>
  <p>Any ideas?</p>
