Ошибка в Google Map V2

Question

Я следую учебнику в https://developers.google.com/maps/documentation/android/start, и я считаю, что для меня нет правильного ответа.

Это мой mainactivity.java с моим MainActivity простирается FragmentActivity:

package com.example.googlemaptest; 

import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 

public class MainActivity extends FragmentActivity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
    } 
} 

И файл XML:

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

манифеста, как показано ниже:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.googlemaptest" 
    android:versionCode="1"

</application> 

</manifest>

Answer 1

Используйте поддержкуMapFragment вместо MapFragment.

<fragment 
    android:id="@+id/map" 
    android:name="com.google.android.gms.maps.SupportMapFragment" 
    /> 

GoogleMap gm; 
//oncreate 
setContentView(R.layout.maps) 
gm = ((SupportMapFragment)(getSupportFragmentManager().findFragmentById(R.id.map))).getMap(); 
gm.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
gm.setMyLocationEnabled(true); 
}
