V2 Maps Library是否需要ACCESS_NETWORK_STATE权限？

Question

我在我发布的应用中使用了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,SecurityException在支持地图片段膨胀时,有时会抛出a :

我已在我的清单中声明了相关权限,并将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？
