🇺🇦 #StandWithUkraine

On Feb. 24, 2022 Russia declared an unprovoked war on Ukraine and launched a full-scale invasion. Russia is currently bombing peaceful Ukrainian cities, including schools and hospitals and attacking civilians who are fleeing conflict zones.

Please support Ukraine by lobbying your governments, protesting peacefully, and donating money to support the people of Ukraine. Below are links to trustworthy organizations that are helping to defend Ukraine in this unprovoked war:

Discovery doesn't work with Android 9

I am having some trouble to get this library working on every Android 9 smartphone i have tested on. This problem is only occouring on Android 9 and the same code runs without any problem on all lower versions.

This is a small code snippet that i use currently to test the mDNS-Discovery:

    var rxDnssd = RxDnssdBindable(context)
    rxDnssd.browse("_https._tcp", "local.")
        .compose(rxDnssd.resolve())
        .compose(rxDnssd.queryRecords())
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe({ Log.d("DNSSD", "foundService: $it" },
                   { throwable -> Log.e("DNSSD", "error", throwable) })

When this code gets executed there are no corresponding debug or error messages in the logs.

I have not seen any api changes with Android 9 to why this should not work anymore and i am clueless at this point.

Any help with this is appreciated!

Empty txt-record not shown

I have an avahid service configuration for a txt record that can be empty:

<txt-record value-format="binary-hex">fname=</txt-record>

In avahi-browse the field is shown:

txt = [... "fname=" ...]

In the BonjourBrowser the field is omitted if it is empty.

Is this a feature or a bug?

Add feature: Register service

Hi Andriy! I tried your app and it's working great. Maybe you can add the feature to register a service. Background: I use Unison in Terminal to sync files with my phone. I'd like to configure Unison to sync to hostname.local instead an IP address.

Just add a switch on the menu bar and advertise a _workstation._tcp service on 'hostname'.local like Avahi does.

cannot find ipv4 address in wifi-5g

Some routers has 5g wifi functions,BonjourBrowser performances perfectly under other circumstances but cannot find ipv4 address in 5gwifi.Also I've tried to convert ipv6 to ipv4 but I failed.

No services found

hello
Under what circumstances can a service not be found

couldn't find libjdns_sd_embedded.so

hi
implementation 'com.github.andriydruk:rx2dnssd:0.9.13'

****.apk!/lib/armeabi, /system/lib, /vendor/lib, /product/lib]]] couldn't find "libjdns_sd_embedded.so"

Publish on F-Droid?

Since this is a FOSS app, it should also be on F-Droid.

Release 2.0.2

The last release for play store was on June 2017. Is there any chance we can get a release with the fixes made since then?

Project is a little bit too complex

Thank you for this demo and I just made my application work properly on my device.I want to give some suggestions no offence,when you are showing some functional project can we just make a simple UI?I know it's suggested to uses fragments instead of activties but is hard to analysize your core code.Again,my thanks!

Nothing found on Galaxy Alpha

I tested your library on a wide range of devices and compared the results with https://play.google.com/store/apps/details?id=com.grokkt.android.bonjour

Only a crappy Samsung Galaxy Alpha with Android 4.4.2 did not show anything while at the same time the other app shows everything just fine. I got the following exception:

I'm pretty sure I did nothing wrong using your library because this app here has the same problem. I hope you have an idea what could be wrong.
