那是我的代码！

package com.example.googlemap;

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

public class MainActivity extends FragmentActivity
{
   @Override
   protected void onCreate(Bundle arg0)
   {
      // TODO Auto-generated method stub        
      super.onCreate(arg0);
      setContentView(R.layout.activity_main);

      SupportMapFragment fragment = new SupportMapFragment();
      getSupportFragmentManager().beginTransaction().add(android.R.id.content, fragment).commit();
   }
}

在我看来，meta-data带有 API 密钥的标签应该放在该application部分内。你的就在它外面。

我在之前的两个项目中使用过 Maps v2，并在applicationXML 元素中添加了 API 密钥。

在这里查看：https ://developers.google.com/maps/documentation/android/start#adding_the_api_key_to_your_application

您的 API 密钥应是元素的子application元素。
