發生錯誤原因分析：
主要錯誤：
02-13 11:58:13.759: ERROR/Database(432): android.database.sqlite.DatabaseObjectNotClosedException: Application did not close the cursor or database object that was opened here
出錯處代碼
SQLiteDatabase db = getWritableDatabase();
意思是指在此處打開數據庫操作之前，應用程序沒有關閉遊標或數據庫對象。
在應用中，對數據庫操作完成後，應該對遊標及數據庫進行關閉操作
if (!cur.isClosed()) {
cur.close();
}
db.close();
解決辦法：
檢查操作數據庫的相關源代碼，增加關閉“cursor or database object”的代碼 。
PS。
