我按照此处的说明http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/ 而另一个基本上说同样的东西，但我无法让它工作。 我（希望）正确导入了google-play-services-lib，并为我的程序提取了SHA1密钥。

这是基本程序的代码 MainActivity.java 

package com.km.googlemapsv2;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.GoogleMap;

public class MainActivity extends ActionBarActivity {

// Google Map
private GoogleMap googleMap;

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

    try {
        // Loading map
        initializeMap();

    } catch (Exception e) {
        e.printStackTrace();
    }

}

/**
 * function to load map. If map is not created it will create it for you
 * */
private void initializeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

@Override
protected void onResume() {
    super.onResume();
    initializeMap();
    }

}

activity_main.xml中

<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"

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

</RelativeLayout>

基本上我只需要移动

<!-- Google Maps API Key -->
<meta-data
 android:name="com.google.android.maps.v2.API_KEY"
 android:value="AIzaSyBf-0hUDrDTK-NOveZrnT8wec5TTTLqjAw" />

<meta-data 
     android:name="com.google.android.gms.version"
     android:value="@integer/google_play_services_version" />

进入应用程序标签。感谢用户名arpit获得答案！

在清单中添加此项并清理项目并再次运行

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

在您的AndroidManifest文件中，在应用程序代码中提供 Google Map API密钥元数据和 Google Play服务元数据：

   <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.km.googlemapsv2"
    android:versionCode="1"
    android:versionName="1.0" >

    ...

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

    <!-- Google Maps API Key -->

         android:value="AIzaSyBf-0hUDrDTK-NOveZrnT8wec5TTTLqjAw" />

    <meta-data 
         android:name="com.google.android.gms.version"

    </application>
