I am building an android application in which I need to parse the data from the Database through JSON using Volley. I have 17,000+ rows in the table, I need to fetch all the row from the table via JSON and I need to store it in SQLite. Once downloaded the user can modify the fields of all row. Once the fields have been modified. The whole data need to be sent back to the server(Like synchronize).

我的问题是，如果我尝试将大量数据下载到我的应用程序中.它崩溃了.有什么办法可以使此应用程序正常工作.还告诉我如何使用Volley解析服务器中的大量数据.

What my problem is, If I attempt to download this huge data to my app. It's getting crashed. Is there any way that I can do to make this app work. Also tell me how to parse huge data from the server using volley.

推荐答案

1-使用Gson解析数据并将其存储在ormlite数据库中.
2-修改数据库表后，应使用与服务器的同步适配器对表进行逐行同步.
3-使服务同步到服务器

1- Use Gson for parsing data and store in ormlite database.
