我最近更新了我的一个应用程序，但在极少数情况下会出现上述错误。仅当用户尝试在现有应用上更新应用时，才会出现此错误。这并非每次都发生在每台设备上。我在Android SQLiteException 上发现了一个类似的问题：无法将 db 的语言环境更改为 'en_US'但是回复并没有解决我的问题。我一直试图从一个小时候开始解决这个问题，但我失败了。我使用了 SQLiteDatabase，所以我没有给出任何通往我的数据库的路径。崩溃报告如下
android.database.sqlite.SQLiteException: Failed to change locale for db '/data/data/com.scoreup/databases/scoreUp' to 'en_US'.
