Android：DataBase中的问题

标签： java android sqlite

我创建了一个数据库，其中包含有关某些地方的信息..然后我从数据库中检索以显示Google地图上的地点..

当我调试应用程序时，此异常发生在IllegalStateException类中的“SQLiteCursor.finalize（）”..

这是一个logcat输出：

这是logcat的图片。也许它更清楚。

如果您不再需要游标，则可以显示异常"SQLiteCursor.finalize()" in IllegalStateException Class。所以，不要忘记为游标执行close()。 这不是关键异常，因此应用程序可以使用它，但是当调试eclipse时会破坏此异常。
