Building on sonida's answer. After calling setDrawerIndicatorEnabled(false), onNavigateUp wasn't being called still. So, I just created a new onClickListener that called it:

public void setDrawerState(boolean isEnabled) {
    if ( isEnabled ) {
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
        drawerToggle.setDrawerIndicatorEnabled(true);
        drawerToggle.syncState();

    }
    else {
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
        drawerToggle.setDrawerIndicatorEnabled(false);
        drawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                onSupportNavigateUp();
            }
        });
        drawerToggle.syncState();
    }
}

also I think

drawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_UNLOCKED);

has been depreciated, but it works fine without it.
