安卓：問題在數據庫

Question

我創建了有關於一些地方..then我從數據庫中檢索到顯示谷歌地圖上的位置信息數據的基礎上..

當我調試應用程序時出現此異常「 SQLiteCursor.finalize（）」中IllegalStateException異常類..

，這是一個logcat的輸出：

而這是用於logcat的圖片。也許它更清楚。

異常"SQLiteCursor.finalize()" in IllegalStateException Class可以，如果你不再需要的時候都不會關閉遊標出現。所以，不要忘記爲光標執行close()。 這不是關鍵的異常，所以應用程序可以忍受這一點，但在此異常調試eclipse中斷時。
