我在PlayStore中有一个应用程序，有些用户报告说他们将手机更新到Android 6后不再有效。与报告关联的堆栈跟踪如下

显然问题与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（在一个应用程序中安装应用程序） lolipop手机＆gt;将手机更新为棉花糖）。棉花糖上的干净安装完美无缺。 我的第一次尝试是棉花糖中的新权限系统，但据我测试，我没有发现任何问题。以防万一，这是权限列表：
<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" />
如果有人知道问题会是什么，那对我有很大帮助。
