title: .apk renamed to .txt in AVD
body: <p>I installed Eclipse ADT but the virtual Android 4.4 keeps renaming apk downloads to txt. I would love to rename them but can't install a file manager to do that because it's an apk too! </p>
  
  <p>I wasn't having this problem with another version of SDK manager/android 4.2.2.</p>
  
  <p>What's the best workaround?</p>
