Question

I have an activity with many fragments that uses action bar and navigation drawer. It has \"home as up\" enabled. I have implemented proper logic that only top level fragmen

Answer 1

Answer/comments of Nikola Despotoski and Andrey Novikov are perfectly correct but I want to mention that after toolbar was replaced with following code:

drawerToggle.setDrawerIndicatorEnabled(false);
drawerToggle.setHomeAsUpIndicator(getV7DrawerToggleDelegate().getThemeUpIndicator());
setSupportActionBar(toolbar);

your activity will receive every onOptionsItemsSelected events even if you enable your drawer toogle again drawerToggle.setDrawerIndicatorEnabled(true); So you need to handle this, I've ended with

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            if (drawerToggle.isDrawerIndicatorEnabled()) {
                return drawerToggle.onOptionsItemSelected(item);
            } else {
                onBackPressed();
                return true;
            }
        default:
            return super.onOptionsItemSelected(item);
    }
}
