Android Nougat: Too many NetworkRequests filed

Question

After continuos use of application on Android Nougat 7.1.1 it started crashing in background, until started up manually. From Firebase I got following log:

Caused by java.lang.IllegalArgumentException: Too many NetworkRequests filed

I checked android marshmallow source code, it doesn't contain code, that throws this error, but master branch does, so we can conclude this error is Nougat specific.

    private void enforceRequestCountLimit() {
        synchronized (mUidToNetworkRequestCount) {
            int networkRequests = mUidToNetworkRequestCount.get(mUid, 0) + 1;
            if (networkRequests >= MAX_NETWORK_REQUESTS_PER_UID) { //MAX_NETWORK_REQUESTS_PER_UID == 100
                throw new IllegalArgumentException("Too many NetworkRequests filed");
            }
            mUidToNetworkRequestCount.put(mUid, networkRequests);
        }
    }

How often does counter of request resets?

How I can get current network request count to decrease activity when it's close to limit?

From my reading of the source code, you might get this from too many `registerNetworkCallback()` calls without corresponding `unregisterNetworkCallback()` calls. Make sure that you are cleaning up these callbacks. — CommonsWare, Jan 31 '17 at 13:06
@YellowJ I've found several `registerNetworkCallback()` in my code, removed it and now everything fine, thanks to @CommonsWare — Dmytro Rostopira, Aug 25 '17 at 12:31
@DimaRostopira Yes indeed. it is in the 3rd party library I am using. Thanks! — YellowJ, Sep 28 '17 at 03:44

Quoting @CommonsWare from the question comments:

What if I don't register networkCallbacks .... ( I don't know. Maybe retrofit is doing it under the hood? – StayCool Jul 21 '20 at 08:09
