close() was never explicitly called on databaseandroid.database.sqlite异常

ERROR/Database(3236): close() was never explicitly called on databaseandroid.database.sqlite.

DatabaseObjectNotClosedException: Application did not close the cursor or database object that was opened here

它会产生一个异常提示，但程序是不会中止。

字面上理解是database没有正常关闭，实际是因为重复实例化了你的database，或者说你连接已经建立，而你又尝试打开另一个连接时才会有异常。所以解决的办法是，保证你只打开一次连接。
