Throwing NullPointer Exception when we call dismiss() explicitly

[jettimadhu]

Hi,
I have tried to call dismiss() in below cases

1. When the Orientation changes
2. When the user presses the device back key
   It throws below error

When I change the orientatton:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.dispatchConfigurationChanged(android.content.res.Configuration)' on a null object reference

Same issue here!

When the Orientation changes your activity is re-created, so you loose the reference to the te current Tooltip.

Can you create a small project to demonstrate this problem?
