Question

My application is using HttpRequest for many times. is there a way to not call Rest for every time?

i.e How maintain cache for Api Request call. and it should also be worked when there is no internet

Answer 1

Android have own classes to cache responses. To turn cache you should call HttpResponseCache.install method. Such as

HttpResponseCache.install(getCacheDir(), 10 * 1024 * 1024); //10MB cache size

and when you open connection call

connection.setUseCaches(true);

Somthing like this

URL url = new URL("http://site.com/");
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setUseCaches(true);
