Android - Make non-cached request

Question

I am trying to fetch an uncached version of this url: https://github.com/vedantroy/image-test/raw/master/version.txt or this url: https://raw.githubusercontent.com/vedantroy/image-test/master/version.txt in Android.

I thought I solved the problem in this post: Fuel Android - Make non-cached request , but I'm still getting cached versions of those two URLs.

How can I fetch uncached versions of the file at those two URLs?

I'm open to using any Java or Kotlin library.

You are probably getting the content from cache because of the header of your last API call. You can change the Control-Cache header to control wheter you want to cache it or not.

For example with retrofit:

@GET("ws/exampleUrl")
Something getSomething(@Header("Cache-Control") String cacheControl);

and set the Cache-Control header to no-cache If you don't want to hold it:

myApi.getSomething(forceRefresh ? "no-cache" : null);
