# THE PROJECT IS ARCHIVED DUE TO THE RUSSIAN INVASION OF UKRAINE
# 🇺🇦 #StandWithUkraine
On Feb. 24, 2022 Russia declared an [unprovoked war on Ukraine](https://war.ukraine.ua/russia-war-crimes/) 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:

* [Donate to KOLO](https://koloua.com/en/)

## Why I created this library?
My [explanation](http://andriydruk.com/post/mdnsresponder/) about why jmDNS, Android NSD Services and Google Nearby API are not good enough, and why I maintain this library.
## Hierarchy
There are two version of mDNSReposder.

## Binaries on MavenCentral
DNSSD library:
```groovy
compile 'com.github.andriydruk:dnssd:0.9.17'
```
RxDNSSD library:
```groovy
compile 'com.github.andriydruk:rxdnssd:0.9.17'
```
Rx2DNSSD library:
```
compile 'com.github.andriydruk:rx2dnssd:0.9.17'
```
* It's built with Andorid NDK 21 for all platforms (1.7 MB). If you prefer another NDK version or subset of platforms, please build it from source with command:
```groovy
./gradlew clean build
```
## How to use
### DNSSD
Dnssd library provides two implementations of DNSSD interface:
DNSSDBindable is an implementation of DNSSD with system's daemon. Use it for Android project with min API higher than 4.1 for an economy of battery consumption (Also some Samsung devices can don't work with this implementation).
**[Update] Since `targetSDK = 31` (Android 12) system's deamon was deprecated by Google. Consider switching to an Embedded version or some other solution.**
```
DNSSD dnssd = new DNSSDBindable(context);
```
DNSSDEmbedded is an implementation of RxDnssd with embedded DNS-SD core. Can be used for any Android device with min API higher than Android 4.0.
```
DNSSD dnssd = new DNSSDEmbedded();
```
##### Register service
```java
try {
registerService = dnssd.register("service_name", "_rxdnssd._tcp", 123,
new RegisterListener() {
@Override
public void serviceRegistered(DNSSDRegistration registration, int flags,
String serviceName, String regType, String domain) {
Log.i("TAG", "Register successfully ");
}
@Override
public void operationFailed(DNSSDService service, int errorCode) {
Log.e("TAG", "error " + errorCode);
}
});
} catch (DNSSDException e) {
Log.e("TAG", "error", e);
}
```
##### Browse services example
```java
try {
browseService = dnssd.browse("_rxdnssd._tcp", new BrowseListener() {
@Override
public void serviceFound(DNSSDService browser, int flags, int ifIndex,
final String serviceName, String regType, String domain) {
Log.i("TAG", "Found " + serviceName);
}
@Override
public void serviceLost(DNSSDService browser, int flags, int ifIndex,
String serviceName, String regType, String domain) {
Log.i("TAG", "Lost " + serviceName);
}
@Override
public void operationFailed(DNSSDService service, int errorCode) {
Log.e("TAG", "error: " + errorCode);
}
});
} catch (DNSSDException e) {
Log.e("TAG", "error", e);
}
```
You can find more samples in app inside this repository.
### RxDNSSD
- RxDnssdBindable
```
RxDnssd rxdnssd = new RxDnssdBindable(context);
```
- RxDnssdEmbedded
```
RxDnssd rxdnssd = new RxDnssdEmbedded();
```
##### Register service
```java
BonjourService bs = new BonjourService.Builder(0, 0, Build.DEVICE, "_rxdnssd._tcp", null).port(123).build();
Subscription subscription = rxdnssd.register(bonjourService)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(service -> {
updateUi();
}, throwable -> {
Log.e("DNSSD", "Error: ", throwable);
});
```
##### Browse services example
```java
Subscription subscription = rxDnssd.browse("_http._tcp", "local.")
.compose(rxDnssd.resolve())
.compose(rxDnssd.queryRecords())
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Action1() {
@Override
public void call(BonjourService bonjourService) {
Log.d("TAG", bonjourService.toString());
}
}, new Action1() {
@Override
public void call(Throwable throwable) {
Log.e("TAG", "error", throwable);
}
});
```
### Rx2DNSSD
- Rx2DnssdBindable
```
Rx2Dnssd rxdnssd = new Rx2DnssdBindable(context);
```
- Rx2DnssdEmbedded
```
Rx2Dnssd rxdnssd = new Rx2DnssdEmbedded();
```
##### Register service
```java
BonjourService bs = new BonjourService.Builder(0, 0, Build.DEVICE, "_rxdnssd._tcp", null).port(123).build();
registerDisposable = rxDnssd.register(bs)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(bonjourService -> {
Log.i("TAG", "Register successfully " + bonjourService.toString());
}, throwable -> {
Log.e("TAG", "error", throwable);
});
```
##### Browse services example
```java
browseDisposable = rxDnssd.browse("_http._tcp", "local.")
.compose(rxDnssd.resolve())
.compose(rxDnssd.queryRecords())
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(bonjourService -> {
Log.d("TAG", bonjourService.toString());
if (bonjourService.isLost()) {
mServiceAdapter.remove(bonjourService);
} else {
mServiceAdapter.add(bonjourService);
}
}, throwable -> Log.e("TAG", "error", throwable));
