Phone的SQLiteDatabase永久锁定

时间：2013-02-08 02:52:20

标签： android android-sqlite sqliteopenhelper

我的Android应用程序正在使用手机的SQLiteDatabase。似乎在应用程序崩溃的某个时刻，突然很多我的页面/片段无法正常工作，因为数据库被永久锁定。

有没有办法手动解锁/删除问题，以便我可以再次开始访问我的其他功能？相同的代码可以在我的其他朋友的手机上使用，所以我相信我需要在我自己的手机上手动解锁数据库，以便再次进行调试。

以下是我的（编辑：FULL）logcat，如果它有帮助：

2 个答案:

答案 0 :(得分：1)

发生这种情况的原因是因为您一次只能打开一个数据库连接。我相信你没有关闭Db连接，或者当你试图写入它时，某些线程已经写入Db。

我建议您从一个SQLOpenHelper（See this example）访问db，或者确保在完成db helper之后关闭所有db helper实例。

答案 1 :(得分：1)

当您关闭应用程序（或系统将其关闭）时，您的数据库连接将被断开并清除。因此，没有“永久锁定”这样的东西。

02-08 10:40:24.195: E/SqliteDatabaseCpp(7212): sqlite3_exec - Failed to set synchronous mode = 1(Normal) 
02-08 10:40:24.205: E/SQLiteDatabase(7212): Failed to open the database. closing it.

这个问题通常是一个线程试图访问数据库，但另一个线程有锁或正在使用它。解决方案：在应用程序中仅使用一个连接到数据库的实例。 一种方法是将实例存储在subbed的Application类中。
