[ttym]

when i call the discovery method multiple times then i got this crash on JNI method:

here is my code snippet:

public void startDiscover(String nsdType) {
rxDnssd.browse(nsdType, "local.")
                    .compose(rxDnssd.resolve())
                    .compose(rxDnssd.queryIPRecords())
                    .subscribeOn(Schedulers.io())
                    .observeOn(AndroidSchedulers.mainThread())
                    .subscribe(bonjourService -> {
                        if (bonjourService.isLost()) {
                            xxxx
                        } else {
                           xxxx
                        }
                    }, throwable -> Log.e("TAG", "error", throwable));
}

and this startDiscovery method may call multiple times

Looks like a memory leak. Please write what version do you use? What version of rxDnssd did you create?

I use Version is 0.9.11
rxDnssd create by rx2Dnssd

Thanks for you time

[andriydruk]

It looks like you use DNSSDEmbedded version of Rx2DNSSD
Please, try 0.9.12. I added fix for an embedded version of library
