使用Google Maps API v2時顯示「不幸的應用程序已停止」錯誤

Question

我無法弄清楚我錯過了什麼。我正在嘗試在我的主要活動中實施一個簡單的Google地圖。谷歌地圖應該簡單地顯示在MainActivity中。

Google API密鑰已在Manifest文件中正確更新。我的項目中包含google-play-services_lib.jar。在Eclipse中創建新的Android項目時，Google API 18被選爲「編譯」。

守則MainActivity.java

package com.example.maptest; 
import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 

public class MainActivity extends FragmentActivity { 

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

} 

守則activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" > 

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

</RelativeLayout> 

代碼在我的AndroidManifest.xml

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

<uses-permission android:name="com.example.googlemaps.permission.MAPS_RECEIVE" /> 

<uses-sdk 
    android:minSdkVersion="12" 
    android:targetSdkVersion="18" /> 

<permission 
    android:name="com.example.googlemaps.permission.MAPS_RECEIVE" 
    android:protectionLevel="signature" />

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 

<uses-feature 
    android:glEsVersion="0x00020000" 
    android:required="true" /> 

<application 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 
    <activity 
     android:name="com.example.maptest.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> 

    <meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="MyActualKey" /> 
    <meta-data 
     android:name="com.google.android.gms.version" 
     android:value="@integer/google_play_services_version" /> 
</application> 

</manifest>

Answer 1

1）您沒有爲google play服務版本指定meta標籤。應該有2個元標籤 - 您的地圖密鑰和播放服務版本：

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

2）Android模擬器沒有安裝GooglePlayServices。由於您使用FragmentActivity從支持庫使用真實設備

UPDATE

3），你必須使用支持地圖片段爲好。這種替換您activity_main佈局：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

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

</RelativeLayout>
