title: Error when starting Android Emulator
body: <p>I am new to Android Studio and fairly new to MacOSX and I have the following error when starting my app in an emulator</p>
  
  <p>03/23 18:17:24: Launching app
  $ adb push /Users/Dave/AndroidStudioProjects/Cookies/app/build/outputs/apk/app-debug.apk /data/local/tmp/com.example.android.cookies
  com.android.ddmlib.SyncException: No such file or directory
  Error while Installing APK</p>
  
  <p>Do I need to create the /data/local/tmp/ folder?
  If yes where do I create it?</p>
