OkHttpClient cannot resolve method setCache

In 3.x a bunch of methods on OkHttpClient were moved into methods on OkHttpClient.Builder. You want something like this:

File httpCacheDirectory = new File(getCacheDir(), "responses");
int cacheSize = 10*1024*1024;
Cache cache = new Cache(httpCacheDirectory, cacheSize);

OkHttpClient client = new OkHttpClient.Builder()
    .addNetworkInterceptor(REWRITE_CACHE_CONTROL_INTERCEPTOR)
    .cache(cache)
    .build();
