Okhttp Cache With Expiration

I am new to OkHttpClient and i don't know how to store cache for only 1 week. So when agent update data, it will update in mobile too after 1 week.

Solution 1:

You can use MaxAge and MaxStale parameter of CacheControl

MaxAge

Sets the maximum age of a cached response. If the cache response's age exceeds MaxAge it will not be used and a network request will be made

MaxStale

Accept cached responses that have exceeded their freshness lifetime by up to MaxStale. If unspecified, stale cache responses will not be used

public Interceptor provideCacheInterceptor(finalint maxDays) {      
    returnnewInterceptor() {       
        @Overridepublic Response intercept(Chain chain)throws IOException {
            Responseresponse= chain.proceed(chain.request());
            CacheControlcacheControl=newCacheControl.Builder()
                .maxAge(maxDays, TimeUnit.DAYS)
                .build();
    
            return response.newBuilder()
                .header(Constants.CACHE_CONTROL, cacheControl.toString())
                .build();
        }
    };
}

And later you can add this to your HttpClient

int MaxCacheDays = 7; 
httpClient.addNetworkInterceptor(provideCacheInterceptor(MaxCacheDays));
