Ich bekommeNullPointerException imonTouchEvent vonCoordinatorLayout.

Ich benutzeDrawerLayout mitCollapsingToolbarLayout von Android-Unterstützung AppCompat v23.0.0 Bibliothek.

Meine Beobachtung ist Absturz zufällig beim Scrollen passierenCollapsingToolbarLayout oder klicken Sie auf Schubladenelemente.

Ist jemand mit diesem Problem konfrontiert? Gibt es eine Möglichkeit, diese Ausnahme zu umgehen?
