When I click on my drawer toggle I get the following exception:
java.lang.IllegalArgumentException: No drawer view found with gravity LEFT
The "Android Drawer" needs to be a direct child node of the "DrawerLayout".
In your example above (re: original question example), you only have a single direct child node under "DrawerLayout" ("LinearLayout"), and no drawer view after it.
Move your drawer view out of your LinearLayout and place it after it.
