ActionBarSherlock: OnOptionsItemSelected doesn't recognize R.id.home

Question

I'm using the ActionBarSherlock library and I'm following the exact steps as suggested here and here to enable navigation to the previous screen.

My code looks like this:

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

and

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // This callback is used only when mSoloFragment == true (see
    // onActivityCreated above)
    switch (item.getItemId()) {
    case android.R.id.home:
        // App icon in Action Bar clicked; go up
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); // Reuse the
                                                            // existing
                                                            // instance
        startActivity(intent);

        return true;
    default:
        return super.onOptionsItemSelected(item);
    }

But R.id.home is not recognized and home shows up in red. :-/ If I use the native actionbar the home declaration takes me to ids.xml file. But here the declaration is not found while I use the ActionBarSherlock Activity. Am I missing something?

just replace this

android.R.id.home

to

R.id.home

and check your code... run it

because

R.layout.* are layouts you provide (in res/layout, for example).

android.R.layout.* are layouts that ship with the Android SDK.

It gave me a suggestion as R.id.homeAsUp, I selected that and it has saved. I'll update this thread once I find out if it's working. – buggydroid Mar 22 '13 at 09:01
I am afraid this is not the correct answer. android.R.id.home is fine. I suspect the minSdkVersion is too low. Should be 11 or higher. – Frank Rem Jan 20 '14 at 08:42
@Frank: if you have used actionbarsharelock then min sdk is 8. am i right? – Dhaval Parmar Jan 20 '14 at 12:55
According to the Android docs, android.R.id.home was introduced in 3.0. Maybe I am missing something. – Frank Rem Jan 20 '14 at 12:58
Thanks. You mean that the R.id.home is defined in ActionBarSherlock? – Frank Rem Jan 20 '14 at 14:39

I know this is an old question but I believe the right answer is missing.

It should be be android.R.id.home because it is a platform resource, so your code is fine.

Make sure your minSdkVersion is 11 or higher since home was introduced in 11.

Brendan - My problem is not with the R error. It's concerned with ActionBarSherlock library. Try to be more specific with your answers. :) Just a suggestion. Thanks anyway. – buggydroid Mar 22 '13 at 09:05
