使用CONFLICT_REPLACE插入时,SQLiteException“无法提交 – 没有事务处于活动状态”

我在更新数据库时遇到了一些麻烦。

这是日志:

这是我用来插入新数据的代码:

 int updateSize = 0; // cvs is an ArrayList array with each entry holding // the new values for a certain table // I know I could use a Map but let's change one thing after another for(ArrayList list : cvs) updateSize += list.size(); Log.d(DEBUG_TAG, "Start updating databases"); Log.d(DEBUG_TAG, "update size: "+updateSize); if(updateSize > 0) { dbHelper = ShaufelDatabaseHelper.getInstance(context); connection = dbHelper.getWritableDatabase(); for(int i=0; i<cvs.length; i++) { String table; switch(i) { case 0: table = "cemeteries"; break; case 1: table = "customers"; break; case 2: table = "graves"; break; case 3: table = "orders"; break; case 4: table = "plants"; break; case 5: table = "plantevents"; break; case 6: table = "services"; break; case 7: table = "serviceevents"; break; default: throw new RuntimeException("wtf"); } Log.d(DEBUG_TAG, "updating table "+table); for(ContentValues cv: cvs[i]) { // replace updated values, insert new ones connection.insertWithOnConflict(table, null, cv, SQLiteDatabase.CONFLICT_REPLACE); } } } 

关于这一点的奇怪之处在于,每次都不会抛出exception。 它更像是这样的:

如果您启动应用程序并登录,则更新将起作用。 如果您然后注销并重新登录(不关闭应用程序),则会再次进行更新,但这次是exception。
如果你关闭应用程序(不只是按回家但是强制关闭android系统)它会再次运行,直到你退出并重新登录。
更新都包含相同的数据(我们目前正在测试这些东西)并且它由相同的代码运行,但它只能工作一半的时间。

这是在HTC Sensation的Android 4.0.3上运行的。

1802SQLITE_IOERR_FSTAT ,当连接仍处于打开状态时删除数据库文件时会发生这种情况。

您是否在更新中删除了任何文件?
