致命信号11-每次退出android谷歌地图活动时崩溃

我在Android Studio中创建了一个带有谷歌地图活动的新测试应用程序。我所有的项目都是由向导创建的，唯一需要修改的文件是build.gradle，以修复一些版本号。我在模拟器中运行它（Google api level 19，android 4.4.2，x86系统映像），应用程序运行正常，api键正确，地图显示。但是，每当我退出活动（应用程序）时，它就会崩溃：

我最近也遇到了同样的问题，但对我来说是由BluetoothSocket生成的：我当时正试图读取与套接字关联的InputStream，这时它已经关闭。像这样的硬崩溃表明设备或模拟器中存在错误，比您的代码中更严重。如果您没有使用NDK，那么Java级别上没有任何东西会导致

SIGSEGV

。如果您可以创建一个复制错误的示例项目，那么您可能希望在“地图问题跟踪器”上提交一个bug。您可能还希望查看硬件是否崩溃，或者这是否只是模拟器的问题。我只是这样做了：如果其他人有类似的问题，请在那里添加详细信息，不要忘记单击星形图标以表明您也对重新解决的问题感兴趣
