public class Map extends FragmentActivity {

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.map);

}

Map.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

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

I've followed the Google dev process and a couple of tutorials but haven't found the answer

Thanks!

Step #1: Get rid of <uses-library android:name="com.google.android.maps" />, as that is not used by Maps V2.

Step #2: If you are on the R22 (or higher) version of the ADT plugin for Eclipse, be sure to fix your build path.

If those do not help, make sure that you have properly attached the Play Services Android library project to your project. For example, if you manually modified your build path (beyond what Step #2 calls for), that wasn't the right way to attach the Play Services Android library project.

It helped but now I'm get an error: android.view.InflateException Binary XML file line #7: Error inflating the class fragment – Mitch Thornton Jun 08 '13 at 23:53
@MitchThornton: Try replacing `class` with `android:name`. Otherwise, post the full stack trace. – CommonsWare Jun 09 '13 at 10:23
Still having problems....I posted the new Logcat above...thanks for your help so far btw – Mitch Thornton Jun 10 '13 at 17:32
@MitchThornton: That still looks like Step #2 and the subsequent paragraph in my answer. – CommonsWare Jun 10 '13 at 17:37
I think it solved the problem for the most part but when I try it on my phone, it says I need to have Google Play on my phone but I already have it – Mitch Thornton Jun 11 '13 at 17:18
@MitchThornton: What you really need is the Play Services Framework. Many devices get that with the Play Store, but not all apparently. Check for it on the Play Store on your device, and install it if you find it. – CommonsWare Jun 11 '13 at 17:23

Add in your fragment attribute android:name="com.google.android.gms.maps.SupportMapFragment" Add full package name in your Manifest in this permission(missing com.): "

<uses-permission android:name="dealtap.permission.MAPS_RECEIVE />

Add google-play-services.jar from extras to your libs, regardless of added library project you already have.

And most important, add in your Activity:

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