Question

我正在尝试制作简单的谷歌地图应用程序，但每当我启动时它都会崩溃..

mainactivity.java

package com.example.google;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;

import android.support.v7.app.ActionBarActivity;
import android.app.FragmentManager;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends ActionBarActivity {
GoogleMap map=null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        if(map==null)
        {
        map=((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
        }
    }

}

activitymain.xml

<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:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.google.MainActivity" >

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

Answer 1

的哪一部分

您应用的AndroidManifest.xml中的必需元数据标记不存在。您必须在＆lt; application＆gt;中包含以下声明： element：＆lt; meta-data android：name =“com.google.android.gms.version”android：value =“@ integer / google_play_services_version”/＆gt;

你不明白吗？您只声明了API密钥，您也应该添加Play服务版本。
