First you add the Navigation back button

   getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);

Then, add the Method in your HostActivity.

 @Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId()==android.R.id.home)
    {
        super.onBackPressed();
        Toast.makeText(this, "OnBAckPressed Works", Toast.LENGTH_SHORT).show();
    }

    return super.onOptionsItemSelected(item);
}

Try this, definitely work.
