Cannot run Android SDK Manager

After the Android SDK or Xamarin updates, should you ever have trouble to run Android SDK Manager and see the exception:

java.lang.NullPointerException
at java.io.File.(File.java:277)
at com.android.sdklib.internal.avd.AvdManager.parseAvdInfo(AvdManager.java:1623)

then just delete directory “users//.android/avd”.

Happy coding!
