的mainfest是

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

     android:minSdkVersion="8"

       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 

     <meta-data 
      android:name="com.google.android.maps.v2.API_KEY" 
      android:value="XXXXXXXXXXXXXXXXXXXXXXXXXX" /> 
    </application> 

</manifest> 

我的活動是：

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android的目標設定爲2.2谷歌的API，我爲我的手機上測試它2.3

請幫助

你分鐘SDK是8.您應該使用支持片段。

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

您的活動必須擴展FragmentActivity

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

確保您已經添加支持庫

還要確保您導入下面的

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