Bom, estou fazendo uma aplicação que envolve mapas, no entanto, esta dando esse erro.

Essa seria a classe principal que trabalha com o mapa

package com.example.mapadeamigos;

import java.io.Serializable;

import com.example.mapadeamigos.mapas.AtualizadorDePosicao;
import com.example.mapadeamigos.mapas.Localizador;
import com.example.mapadeamigos.mapas.MapaFragment;
import com.google.android.gms.maps.model.LatLng;

import android.content.Context;
import android.content.Intent;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;

public class AmigoMapa extends FragmentActivity {
	
	private AtualizadorDePosicao atualizadorDePosicao;
	private Amigos escolha;

	@Override
	protected void onCreate(Bundle arg0) {
		super.onCreate(arg0);
		setContentView(R.layout.mapa_layout);
		FragmentManager manager = getSupportFragmentManager();
		FragmentTransaction transaction = manager.beginTransaction();
		MapaFragment mapa=new MapaFragment();
		transaction.replace(R.id.mapa_amigos, mapa);
		transaction.commit();
		Intent intent = getIntent();
		escolha = (Amigos) intent.getSerializableExtra("procura");
		if(escolha!=null){
			Localizador localizador = new Localizador(this);
			LatLng local = localizador.getCordenada(escolha.getEndereco());
			mapa.carregaMapa(local);
		} else {
			atualizadorDePosicao = new AtualizadorDePosicao(this,mapa);
		}
		
	}
	
	@Override
	protected void onDestroy() {
		// TODO Auto-generated method stub
		super.onDestroy();
		if(escolha==null){
			atualizadorDePosicao.cancelar();			
		}		
	}

}

classe do gps

package com.example.mapadeamigos.mapas;

import com.google.android.gms.maps.model.LatLng;

import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;

public class AtualizadorDePosicao implements LocationListener {
	
	
	private LocationManager locationManager;
	private final MapaFragment mapa;

	public AtualizadorDePosicao(Activity activity,MapaFragment mapa) {
		this.mapa = mapa;
		locationManager = (LocationManager) activity.getSystemService(Context.LOCATION_SERVICE);
		String provider=LocationManager.GPS_PROVIDER;
		long minTime=20000;//segundos
		float minDistance=20;//metros
		locationManager.requestLocationUpdates(provider, minTime, minDistance, this);
	}

	@Override
	public void onLocationChanged(Location novaLocalizacao) {
		double latitude = novaLocalizacao.getLatitude();
		double longitude = novaLocalizacao.getLongitude();
		LatLng local=new LatLng(latitude, longitude);
		mapa.carregaMapa(local);
	}

	@Override
	public void onProviderDisabled(String provider) {
		// TODO Auto-generated method stub

	}

	@Override
	public void onProviderEnabled(String provider) {
		// TODO Auto-generated method stub

	}

	@Override
	public void onStatusChanged(String provider, int status, Bundle extras) {
		// TODO Auto-generated method stub

	}

	public void cancelar() {
		locationManager.removeUpdates(this);
		
	}

}

E finalmente MapaFragment

package com.example.mapadeamigos.mapas;

import java.util.List;

import android.support.v4.app.FragmentActivity;

import com.example.mapadeamigos.Amigos;
import com.example.mapadeamigos.DAO.AmigosDAO;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MapaFragment extends SupportMapFragment {
	
	@Override
	public void onResume() {
		super.onResume();
		FragmentActivity context = getActivity();
		
		//coloca os amigos no mapa
		AmigosDAO dao = new AmigosDAO(context);
		List&lt;Amigos&gt; amigos = dao.getList();
		for(Amigos amigo:amigos){
			GoogleMap mapa = getMap();
			LatLng localAmigo=new Localizador(context).getCordenada(amigo.getEndereco());
			MarkerOptions options=new MarkerOptions().title(amigo.getNome()).position(localAmigo);
			mapa.addMarker(options);
		}
		dao.close();
	}
	
	//centraliza mapa
	public void carregaMapa(LatLng local) {
		GoogleMap map = getMap();		
		CameraUpdate update=CameraUpdateFactory.newLatLngZoom(local, 15);
		map.animateCamera(update);
		
	}

}
