Question

我在我发布的应用中使用Android V2 Google地图库（Google Play服务）。我一直看到Google Play中出现的零星异常似乎表明支持地图片段偶尔会尝试检查网络状态。但是，库文档未提及此权限是必需的。我不直接在我的应用程序中检查网络状态，所以我没有声明此权限。因此，在膨胀支持地图片段时，有时会抛出SecurityException：

我已在我的清单中声明了相关权限，并会查看是否可以解决问题。然而，有人认为这只会发生在某些设备而不是其他设备上。例如，这在我们的内部测试设备和许多其他设备上运行良好。有没有人对这个神秘的问题有任何见解？它可能是由一个程序错误引起的吗？

编辑1：使用Google Play服务库的2.0.10版（541717-10）时发生此错误。

Answer 1

使用最新版本的Google Play服务库，documentation has been updated表示需要此权限。

release notes表示需要此权限的原因：

改善了恢复网络连接的速度。此修复程序需要ACCESS_NETWORK_STATE权限。

Answer 2

是。任何使用getActiveNetworkInfo()方法都需要网络状态访问权限。

你的Manifest中的以下行应该可以解决问题：

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

V2 Maps Library是否需要ACCESS_NETWORK_STATE权限？
