I suggest to refactor your application to single activity structure. This will help to solve both of your problems.

• You may just open the drawer in activity onCreate method. It is called when activity created, with single activity - when app started.
• Save that drawer was opened to instance state if you need more accuracy here and don't want the drawer to be opened on activity recreation events (states when system decides to destroy your activity to release memory)
• use fragments for showing app screens
• open drawer in this single activity and manage toolbar from activity so it could be opened on every screen

Single activity is the way google recommends to structure apps.
