I changed from the original ActionBar to the AppCompat Toolbar and setSupportActionBar(toolbar). When I am using getSupportActionBar() and setDisplayHomeAsUpEnabled(true) for the back arrow, the click never calls onOptionsItemSelected or any other listener method.
Do I have to implement some special listener for it? Befor everything was working just fine.
EDIT: Initialise the ActionBar:
mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
mActionBar = getSupportActionBar();
mActionBar.setHomeButtonEnabled(true);
and after replacing the content with a Fragment I do this:
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
mDrawerToggle.setDrawerIndicatorEnabled(false);
mActionBar.setDisplayHomeAsUpEnabled(true);
