Question

即使我导入：

 import android.support.v4.app.FragmentActivity;  
 import com.google.android.gms.maps.SupportMapFragment;

我仍然收到此错误消息：

不能在我的AVD中工作，或直接在我的手机上工作。我导入google-play-services_lib并将引用放在此地图项目中。用min sdk 8 ......

这是我的编码，

我的布局文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:paddingBottom="@dimen/activity_vertical_margin"
  android:paddingLeft="@dimen/activity_horizontal_margin"
  android:paddingRight="@dimen/activity_horizontal_margin"
  android:paddingTop="@dimen/activity_vertical_margin"
  tools:context=".MainActivity" >

<fragment
 class="com.google.android.gms.maps.SupportMapFragment"
 android:id="@+id/map"  
 android:layout_width="match_parent"
 android:layout_height="match_parent"/>

</RelativeLayout>

MainActivity：

package com.example.googlev2map;

import android.support.v4.app.FragmentActivity;  
import com.google.android.gms.maps.SupportMapFragment;

import android.os.Bundle;

public class MainActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    }
}

我的Manifest.xml：
