主要节日是

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.williamroma.example"
    android:versionCode="1"
    android:versionName="1.0" >

我的活动是：

public class MainActivity extends Activity {

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

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"/>

我将android目标设置为2.2 google api，我在手机上测试它2.3

请帮助

你的min sdk是8.你应该使用支持片段。

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

您的活动必须延长FragmentActivity

SupportMapFragment fm = (SupportMapFragment)  getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap();

确保您已添加支持库

同时确保导入以下内容

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