Question

我在服务器json url中有值，然后获取这些值，然后存储到本地数据库中。但是当我得到这些值并存储到本地数据库中时，我无法打开数据库。

SQLiteDatabase checkDB = null;
            try {
                checkDB = SQLiteDatabase.openDatabase("/data/data/com.example.testjson/databases/Details", null,
                        SQLiteDatabase.OPEN_READONLY);
                checkDB.close();


                db.updateDetails(store);


            } catch (SQLiteException e) {
                // database doesn't exist yet.

                // Log.i("DatabaseInserted", "No Found");

                 db.insertDetails(store);

            }

您在更新或插入之前关闭了Db！

将陈述交换为：

db.updateDetails(store);
checkDB.close();
