I need to hit serverside Database and retrieve or post data from server side DataBase.
what i have is .json files and path for the api
How to do this???
Do I need to use any third party libraries ??
If you do not want to use third party libraries, you can just use HttpUrlConnection class which is a pure Java Library. On the other hand there are some third party which are very easy and clear to send and receive requests such as Volley and Retrofit etc.
It is your decision to use whatever you like. I would recommend you to use Volley, because it is a framework of Google.
You can use http://square.github.io/okhttp/ to send or receive data from the server. Tutorial available in http://www.vogella.com/tutorials/JavaLibrary-OkHttp/article.html, Hope this may help you..
