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

Essa seria a classe principal que trabalha com o mapa

[code]
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();			
	}		
}

}[/code]

classe do gps

[code]
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);
	
}

}[/code]

E finalmente MapaFragment

[code]
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<Amigos> 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);
	
}

}[/code]
