GoogleMap Fragment in ActionBar Tabs (with ActionBarSherlock)

Question

I'm running into a (I'm sure) silly problem and could use another set of eyes.

I have an app that requires GoogleMaps be shown in several places in the app. I have it successfully shown in my main activity, all Play libraries are in place, V2 key is all set-up, etc.

My (truncated) mapview.xml looks like:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.SupportMapFragment" />

As I said, on the main activity, I can set the contentView correctly and draw a map, no problem.

However, on a different activity, I'm implementing tabs:

    ActionBar actionBar = getSupportActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    // Add tabs
    actionBar.addTab(actionBar.newTab().setText(R.string.map).setTabListener(this));

Here's where I run into trouble. On the tab selected listener, I do the following, which I'm sure is going wrong (Layout is an empty linear layout):

    GoogleMapFragment mapFragment = new GoogleMapFragment();
    fragmentTransaction = supportFragmentManager.beginTransaction();
    fragmentTransaction.addToBackStack(null);
    fragmentTransaction.replace(layout.getId(), mapFragment);
    fragmentTransaction.commit();

That map fragment looks like:

@Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.map_view, null);
  }

When it runs, I get various errors depending on how I tweak this, such as

android.view.InflateException: Binary XML file line #2: Error inflating class fragment
Caused by: java.lang.IllegalArgumentException: Binary XML file line #2: Duplicate id 0x7f040058, tag null, or parent id 0x0 with another fragment for com.google.android.gms.maps.SupportMapFragment

Like I said, I'm sure this is wrong, it seems like I'm trying to inflate a fragment twice, or perhaps running into issues by using the same fragment in two spots in the app.

At this point I'm not sure how to fix it. Any advice would be greatly appreciated.

you have already define the layout of the fragment in the xml file so you don't have to add it in the runtime, just pass the fragment layout (mapview.xml in your case) as a parameter in setContentView of your activity.

actually i can not see where are you using the mapFragment in your code. – Adil Mar 11 '13 at 23:43
Sorry, there was a typo, corrected. I use it on the replace() call. – Mike P. Mar 12 '13 at 00:01
and the GoogleMapFragment extends what class? – Adil Mar 12 '13 at 01:15

Try use MapView instead of Fragment in your layout.

<com.google.android.gms.maps.MapView
    android:id="@+id/map_view"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

`MapView` is deprecated in v2; it also does not work here. But thank you for the suggestion! – Mike P. Mar 12 '13 at 19:28
