Same issue with the Rx2DnssdBindable version, I am using jdk 1.8
Is there any issue in my code ?

public void discover()
{
clear();
mRxDnssd = new Rx2DnssdBindable(this.mContext);
Log.d("TAG", "Service Discover called from NsdHelper");
mDisposable = mRxDnssd.browse("_services._dns-sd._udp", "local.")
.compose(mRxDnssd.resolve())
.compose(mRxDnssd.queryIPRecords())
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(bonjourService -> {
Log.d("TAG", bonjourService.toString());
if (bonjourService.isLost()) {
Log.d(TAG, "Service discovery failed");
} else {
Log.d(TAG, "Service discovery found");
serviceArr.add(bonjourService);
handler.networkDiscover(serviceArr);
}
}, throwable -> Log.e("TAG", " discover error is", throwable));

}

public void clear()
{
    if (mDisposable != null) {
        mDisposable.dispose();
    }

    mDisposable = null;
}

You can't resolve services from _services._dns-sd._udp. You should just browse them, retrieve information about domains in your local network. And then start browsing in a particular domain.
Please take a look at BonjourBrowser
