NavUtils.navigateUpTo() does not start any Activity

Question

I have two activities

• MainActivity
• DeepLinkActivity

I set up everything to use the NavUtils for navi

Answer 1

It doesn't work for me too. So I handle up this way:

   @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == android.R.id.home) {

                Intent intent = new Intent(this, MainActivity.class);
                startActivity(intent);
                finish();
                return true;

        }
        return super.onOptionsItemSelected(item);
    }

My MainActivity is marked as singleTask in android manifest

android:launchMode="singleTask"
