升级到Android 6（棉花糖）后的SQLiteCantoPendDatabaseException

我在PlayStore中有一个应用程序，一些用户报告说，在他们将手机升级到android 6后，该应用程序不再工作。与报告关联的堆栈跟踪如下所示

显然，这个问题与ActiveAndroid（我在这个应用程序中使用）无法打开数据库有关，但我无法重现错误，因为它的条件非常具体（在lolipop手机中安装应用程序>将手机更新为棉花糖）。一个干净的棉花糖安装工程完美。 我的第一个想法是棉花糖中的新权限系统，但就我测试而言，我没有发现任何问题。以防万一，以下是权限列表：

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.VIBRATE" />

如果有人知道问题出在哪里，那会对我有很大帮助
