Android Google Maps V2 Error inflating fragment

Question

I've seen dozens of similar problems but none have seemed to fix my issue. I have an app that uses google maps v2 (previously used v1). I imported google-play-services and android-support-v4, and created an activity that extended SupportFragment (also tried just fragment). I added all permissions and my key to the manifest, and created a fragment in my layout folder which defines the map. However, my app crashes every time I call setContentView on my fragment within my activity. I imported android.support.v4.app.FragmentActivity and android.support.v4.app.Fragment in this activity, but get an error trying to inflate the fragment. The logcat log is listed below. Thanks in advance!

public class ManualCheckInMapActivity extends android.support.v4.app.FragmentActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_fragment);
         }
}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    
    android:layout_width="match_parent"    
    android:layout_height="match_parent"    
    android:orientation="vertical" >     
    <fragment        
        android:name="com.google.android.gms.maps.SupportMapFragment"             
        android:id="@+id/map"        
        android:layout_width="match_parent"        
        android:layout_height="match_parent" />
</LinearLayout>

UPDATE: I tried cleaning the project, but now get this error. I'm still new at this, no maybe I did not add the libraries properly?
