I have been following the Android getting started docs and when I try to run the project I get:
!MESSAGE An internal error occurred during: "Launching HelloAndroid".
!STACK 0
java.lang.NullPointerException
at com.android.ide.eclipse.adt.internal.launch.AndroidLaunchController.launch(Unknown Source)
The application doesn’t launch.
On Top Menu go to “Run” then “Run Configurations” and select your target virtual device. Click apply, and then run the project.
