How to retry HTTP requests with OkHttp/Retrofit?

Question

I am using Retrofit/OkHttp (1.6) in my Android project.

I don\'t find any request retry mechanism built-in to either of them. On searching more, I read OkHttp seems

Just want to share my version. It uses rxJava retryWhen method. My version retries connection every N=15 sec and almost immediately emit retry when internet connection recover.

public class RetryWithDelayOrInternet implements Function, Flowable> {
public static boolean isInternetUp;
private int retryCount;

@Override
public Flowable apply(final Flowable attempts) {
    return Flowable.fromPublisher(s -> {
        while (true) {
            retryCount++;
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                attempts.subscribe(s);
                break;
            }
            if (isInternetUp || retryCount == 15) {
                retryCount = 0;
                s.onNext(new Object());
            }
        }
    })
            .subscribeOn(Schedulers.single());
}}

And you should use it before .subscribe like this:

.retryWhen(new RetryWithDelayOrInternet())

You should manually change isInternetUp field

public class InternetConnectionReceiver extends BroadcastReceiver {


@Override
public void onReceive(Context context, Intent intent) {
    boolean networkAvailable = isNetworkAvailable(context);
    RetryWithDelayOrInternet.isInternetUp = networkAvailable;
}
public static boolean isNetworkAvailable(Context context) {
    ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}}
