android.database.sqlite.sqliteDatabaseLockedException：数据库被锁定(代码5)

接着

导致：android.database.sqlite.sqliteException：无法将db’/data/data/com.airlocksoftware.hackernews/databases/hacker_news_cache.db’的区域设置更改为“en_US”.

这是在Android 2.3 – 4.2.1的设备上,以及在我尝试连接到数据库的应用程序的多个位置.我使用它后关闭数据库.

我找不到关于“无法更改数据库区域设置”异常的信息.当我看到source for SQLiteConnection (line 386)时,似乎是“android_Metadata”表或“使用新的区域设置更新索引”的问题.

Here is the code that’s causing the exception (on Github).
