应用已停止工作-片段布局-Google Maps API v2

Question

I saw a lot of questions on stack overflow and no answer solved my problem, i tried to set a layout to the fragment and the app stops working again and again, i tried too many different templates for the fragment to be in relative layout and to be on it's own without relative layout and nothing happens but stops.

 <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 xmlns:map="http://schemas.android.com/apk/res-auto"
 android:layout_width="match_parent"
  android:layout_height="match_parent"
 tools:context=".MainActivity" >
<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />
 </RelativeLayout> 

when i replace the fragment with a textview or button the app works, thank you very much.

Here's my java code, the app stops when i hash the map code too, i believe it's something in the layout.

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class MainActivity extends Activity {
      static final LatLng HAMBURG = new LatLng(53.558, 9.927);
      static final LatLng KIEL = new LatLng(53.551, 9.993);
      private GoogleMap map;

      @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
            .getMap();

        if (map!=null){
          Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
              .title("Hamburg"));
          Marker kiel = map.addMarker(new MarkerOptions()
              .position(KIEL)
              .title("Kiel")
              .snippet("Kiel is cool")
              .icon(BitmapDescriptorFactory
                  .fromResource(R.drawable.ic_launcher)));
        }

      } 
}

Please post the log as it is not clear from your question.
One possible mistake can be => You are using MapFragment which extends Fragment . Try using SupportMapFragment.
