【问题描述】：

我一直在向我的一个 android 项目添加地图，当我的班级加载带有地图片段的 XML 文件时，它崩溃了，我正在学习本教程

(https://developers.google.com/maps/documentation/android/start#the_google_maps_api_key)

我使用的是 Nexus 7 (Jellybean 4.1)，所以这应该不是问题，这是我的课程：

package com.app.thetoolstore;

import android.app.Activity;
import android.os.Bundle;

public class Tool_map extends Activity

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

这是我的 XML：

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_
android:layout_
android:background="#001" >


<fragment xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/map"
      android:layout_
      android:layout_
      android:name="com.google.android.gms.maps.MapFragment"/>



</LinearLayout>

最后是我的堆栈跟踪：

更新

我使用本教程 https://docs.google.com/document/pub?id=19nQzvKP-CVLd7_VrpwnHfl-AE9fjbJySowONZZtNHzw 解决了这个问题，特别是我遇到了 libs 和 google-pay 服务的问题。

【参考方案1】：

嗯，很多问题 1）你需要使用FragmentActivity而不是Activity

2) android:name="com.google.android.gms.maps.MapFragment" 替换为 android:name="com.google.android.gms.maps.SupportMapFragment"/>

3) 您需要在清单文件中添加您的密钥并使用 Google Android Map API v2

4) 参考本教程http://www.vogella.com/articles/AndroidGoogleMaps/article.html

【讨论】：

为什么他需要改变这一行：com.google.android.gms.maps.SupportMapFragment 并且他已经给出了链接developers.google.com/maps/documentation/android/…你读过问题了吗？？
