Android 电话'；的SQLITE数据库已永久锁定

我的android应用程序正在利用手机的Sqlite数据库。似乎在应用程序崩溃的某个时刻，突然间我的许多页面/片段无法工作，因为数据库被永久锁定

是否有办法手动解锁/排除问题，以便我可以再次开始访问其他功能？同样的代码也适用于我其他朋友的手机，因此我认为我需要手动解锁我自己手机上的数据库，以便再次进行调试

下面是我的（编辑：完整）日志，如果有帮助：

发生这种情况的原因是，一次只能打开一个到数据库的连接。我相信您没有关闭数据库连接，或者在尝试写入数据库时，某个线程已经在写入数据库

---

我建议您从一个SQLOpenHelper（）访问db，或者确保在完成db Helper的所有实例后关闭它们。

当应用程序关闭（或系统终止）时，您与数据库的连接将断开并清理。因此，不存在“永久锁定”这样的事情

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：在应用程序中只使用一个数据库连接实例。

---

一种方法是将实例存储在子应用程序类中。

我已经尝试过在构造函数中关闭数据库，但仍然不起作用。。。public PlaceDataSource（Context Context）{dbHelper=new MySQLiteHelper（Context）；dbHelper.close（）；}在代码中执行完sql语句后关闭连接。结束语应该在那之后。请参阅此确定注释，我将再次查看访问数据库的代码。。。thanksok指出，我将再次查看访问数据库的代码。。。谢谢虽然我有点困惑，为什么同样的代码会在我其他朋友的手机上工作，但在我的手机上却不工作。这里有一个类似的代码，我真的不明白。导致上面的logcat的按钮只调用了连接的一个实例，这就是为什么我的其他朋友的手机上的一切仍然正常。为什么只有我的手机不工作？你试过卸载应用程序或重启手机吗？如果在应用程序启动时尝试访问数据库（如果没有）。是的，我在过去几个小时内已多次卸载，并重新运行代码。还是不行。但它适用于所有其他手机，这让我认为这是电话问题，而不是代码问题。。。发布完整的日志会有帮助吗=X
