我今天的大项目是将我的应用程序迁移到新的 Google Maps API V2。但是，现在我遇到了一个错误，我似乎无法找到根本原因。

我的堆栈跟踪如下所示：

我的活动课程如下所示：

package com.mobile.barwatch;

import android.app.Activity;
import android.os.Bundle;
import com.google.android.gcm.GCMRegistrar;
import com.google.android.gms.common.*;
import com.mobile.barwatch.tasks.*;
import com.mobile.barwatch.models.Constants;

public class TestActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {           
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_screen);              
    }
}

我的布局文件如下所示：

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/mapview"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      class="com.google.android.gms.maps.MapFragment"/>

我的清单的相关部分如下所示：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mobile.barwatch"
    android:versionCode="1"
    android:versionName="1.0" >

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

    <application    
        android:allowBackup="true"    
        android:icon="@drawable/ic_launcher_barwatch"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
    ....
    <activity android:name="TestActivity" 
              android:label="@string/app_name">
    </activity>
    <meta-data android:name="com.google.android.maps.v2.xx"
               android:value="xx"/>       
    </application>       
</manifest>

我真的把我的头撞在墙上，所以任何帮助都将不胜感激。

好的，感谢 A--C 和 qzikl 的回复，我能够找出我的问题所在。填写清单时，我有：

 <meta-data android:name="com.google.android.maps.v2.xx"
            android:value="xx"/>

其中 xx 是我的 api 密钥。实际上，它应该是：

 <meta-data android:name="com.google.android.maps.v2.API_KEY"
            android:value="xx"/>

所以导致我所有错误的原因是我在 API_KEY 中填写了我的 api 密钥，而我应该只为值这样做。

您的 LogCat 显示另一个错误，例如：

12-17 17:16:20.366：E/AndroidRuntime(3634)：原因：android.view.InflateException：二进制 XML 文件第 2 行：膨胀类片段时出错

它是所有问题的线索。如您所见，其中包含的“类”表达错误，但此时我不知道解决方案。

堆栈跟踪包括您的答案：

12-17 17:16:20.366：E/AndroidRuntime(3634)：原因：java.lang.RuntimeException：找不到 API 密钥。检查它是否在 AndroidManifest.xml 的元素中

您需要获取 API 密钥并将其包含在清单中。看起来你有一些东西在那里，但也许它被编辑掉了？
