要为 Google Map 充气，您需要在清单中添加以下权限。它在您的 logcat 错误中明确定义。

原因：java.lang.SecurityException：地图 API 需要在 AndroidManifest.xml 中设置额外的以下权限以确保正确的行为：

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

还要确保您还添加了以下权限

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <!-- External storage for caching. -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <!-- Location -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

您的 logcat 清楚地说：

 Caused by: java.lang.SecurityException: The Maps API requires the additional following permissions to be set in the AndroidManifest.xml to 

 ensure a correct behavior: 03-10 16:17:37.977: E/AndroidRuntime(24296): 
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

你需要permission在你的manifest.xml

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

出于 Internet 安全原因，您需要将此权限添加到清单文件。

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