我今天的大项目是将我的应用迁移到新的Google Maps API V2。但是，我现在遇到一个错误，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：

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看起来像这样：

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

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="15" />
    <uses-feature
        android:glEsVersion="0x00020000"
    android:required="true"/>

            android:protectionLevel="signature"/>
    <permission android:name="com.mobile.barwatch.permission.C2D_MESSAGE"

    <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>

我真的把头靠在墙上，所以任何帮助都会非常感激。

4 个答案:

答案 0 :(得分：6)

好的，感谢A - C和qzikl的回复，我能够找出问题所在。在填写我的清单时，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"/>

因此导致我所有错误的原因是我使用我的api密钥填写API_KEY，我只应该为该值填写。

答案 1 :(得分：1)

你的LogCat显示了另一个错误：

  

12-17 17：16：20.366：E / AndroidRuntime（3634）：引起：   android.view.InflateException：二进制XML文件行＃2：错误   膨胀类片段

这是所有问题的线索。正如你所看到的那样，“类”中包含了错误的表达式，但此刻我还不知道解决方案。

答案 2 :(得分：0)

堆栈跟踪包括您的答案：

12-17 17：16：20.366：E / AndroidRuntime（3634）：引起：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。看起来你已经有了一些东西，但也许它已被删除？

答案 3 :(得分：0)

请尝试按此操作以获取新的API密钥https://docs.google.com/document/pub?id=19nQzvKP-CVLd7_VrpwnHfl-AE9fjbJySowONZZtNHzw
