Android 谷歌地图未显示在模拟器上

Question

我正在尝试实现这个例子 http://www.javacodegeeks.com/2011/02/android-google-maps-tutorial.html我已经完全按照所有步骤进行操作，但在模拟器中， map 没有显示，它只显示框。有人知道我在做什么错吗？下面是 Logcat

这是我的 list 文件，

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

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".GmapActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
     <uses-library android:name="com.google.android.maps" />

</application>
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>

好吧，这是签名 key 的一个小问题，实际上您已经使用自己的 keystore 获取了 map key ，但目前您的应用程序使用默认的 android debug.keystore 进行了签名。使用生成映射 key 的 keystore 对您的应用程序进行签名，然后在模拟器上安装并运行它
