<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />

</RelativeLayout>

my map activity

package com.jr.haliotest;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.util.Log;

import com.google.android.gms.maps.CameraUpdateFactory;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_view_layout); //fails here
        mPosition = getIntent().getParcelableExtra(INTENT_EXTRA_POSITION);
        mCameraPosition = new CameraPosition(new LatLng(
                mPosition.getLattitude(), mPosition.getLongetude()), 0, 0, 0);
        initialiseView();
    }

    private void initialiseView() {

        googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

        if (googleMap == null) {
            Log.d("", "Map wasnt loaded properly");
        } else {
            Log.d("", "Map loaded fine");
            googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        }

        googleMap.moveCamera(CameraUpdateFactory
                .newCameraPosition(mCameraPosition));

    }
}

it works fine if i use MapFragment objects instead of the supported objects.

any ideas? what am i missing? tried cleaning, closing eclipse, reinstalling app, no joy

I managed to get it to work.

here are concrete steps on how to use supported libs with google map v2.

copy google play service lib into your lib folder
copy android supported v4 lib in your lib folder
Add 1 and 2 to your build path
import google play service project into your workspace
select your project and rigght click>properties>android>add project lib(the google play service) and do not tick "is library"
Select the google play service project and right click and go to properties>android>tick "is lib"
Use FragmentActivity and use Support to use supported libs.
do clean and rebuild, exit eclipse, uninstall app previously on your device, load eclipse and do another clean and rebuild. It should now all work

You need to get the Google Play SDK:

http://developer.android.com/google/play-services/index.html

Basically, you may have the code in your extras directory, so you import it into your workspace, then compile it, add it to your project as a library and you should be set.

Thats exactly what i did already. i have the google-play-service.jar on my libs folder – Jono Mar 29 '13 at 00:40
i added the actual project folder as a dependency for my project and now it saying it cannot run the Android library – Jono Mar 29 '13 at 00:53
Are you trying to run the google play project? Otherwise you may want to go into detail with what you are doing. If I right-click on my project and do "run as ..." it finds the library but runs my project. – James Black Mar 29 '13 at 01:22
