Am new for android development am really confused where to start with even after lots of research.

对于Android开发而言，我很难搞清楚，即使经过大量研究，也要从哪里开始。

I made a connection with server and fetched the data successfully and I stored it in sharedpreferences when ever the recent data is updated in server that must be displayed and saved into my sharedpreferences. how can I achieve this so far I have used volley to make connection with server how to fetch only recent data from server is there any idea for that as beginner.

我与服务器建立了连接并成功获取数据，并且当服务器中的最新数据更新时，我将其存储在sharedpreferences中，必须显示并保存到我的共享首选项中。到目前为止我如何实现这一点我已经使用volley与服务器建立连接如何从服务器获取最近的数据是否有任何想法作为初学者。

I really confused how to do this This may be dumb question but as of now I struck with this Please share your ideas !!!
