Caused by: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

When using Toolbar class with AppCompat v7 support library build v22+, you must use a parent theme with NoActionBar. For example, Theme.AppCompat.NoActionBar
