相关疑难解决方法(0)

我最近更新了我的一个(开源)Android应用程序,我的用户正在获得一个我无法复制的例外.关键部分是:

android.database.sqlite.SQLiteDatabaseLockedException: database is locked (code 5)

然后

Caused by: android.database.sqlite.SQLiteException: Failed to change locale for db '/data/data/com.airlocksoftware.hackernews/databases/hacker_news_cache.db' to 'en_US'.

这种情况发生在使用Android 2.3 - 4.2.1的设备上,并且在我尝试连接数据库的应用程序中的多个位置.我使用它后关闭数据库.

我找不到有关"未能更改db语言环境"异常的更多信息.当我查看SQLiteConnection的源代码(第386行)时,它似乎是'android_metadata'表或'使用新的语言环境更新索引'的问题.

这是导致异常的代码(在Github上).
