# DataChannel Native
Native platform (Android/iOS/tvOS/macOS) wrapper for [paullouisageneau/libdatachannel](https://github.com/paullouisageneau/libdatachannel): C/C++ WebRTC network library.
## Android
### Add dependency
TODO
### Minimum example
```kotlin
import com.cdnbye.libdc.DataChannel
import com.cdnbye.libdc.DcMessageCallback
import com.cdnbye.libdc.LibDC
import com.cdnbye.libdc.LogLevel.DEBUG
import com.cdnbye.libdc.PeerConnection
import com.cdnbye.libdc.createDataChannel
import com.cdnbye.libdc.rtcConfiguration
// inject custom logger
PeerConnection.initLogger(DEBUG) { level, message ->
// log the message
}
// create config and pc
val config = rtcConfiguration()
val pc1 = PeerConnection.create(config)
val pc2 = PeerConnection.create(config)
// observe local sdp, and set as remote sdp in other pc
pc1?.onLocalDescription {
pc2?.setRemoteDescription(it)
}
pc2?.onLocalDescription {
pc1?.setRemoteDescription(it)
}
// observe ICE candidate, and add to other pc
pc1?.onLocalCandidate { candidate, mid ->
pc2?.addRemoteCandidate(candidate, mid)
}
pc2?.onLocalCandidate { candidate, mid ->
pc1?.addRemoteCandidate(candidate, mid)
}
// observe ICE connection state
pc1?.onStateChange {
// xxx
}
pc2?.onStateChange {
// xxx
}
// observe ICE candidate gathering state
pc1?.onGatheringStateChange {
// xxx
}
pc2?.onGatheringStateChange {
// xxx
}
// observe incoming dc
pc2?.onDataChannel {
// observe dc message
it?.onMessage(object : DcMessageCallback {
override fun onText(msg: String) {
// xxx
}
override fun onBinary(msg: ByteArray) {
// xxx
}
})
// send message
sendMsg(it!!, "pc2", msgCount)
}
// create dc
val dc1 = pc1?.createDataChannel("test")
// observe dc open event
dc1?.onOpen {
// send message
sendMsg(dc1, "pc1", msgCount)
}
// observe dc message
dc1?.onMessage(object : DcMessageCallback {
override fun onText(msg: String) {
// xxx
}
override fun onBinary(msg: ByteArray) {
// xxx
}
})
```
## Apple OS family
The API is almost the same as Android, the difference is just the difference between Kotlin and Swift.
## Development
Before start building, run commands below:
```bash
git submodule update --recursive --init
./run_djinni.sh
# for Android
./build_openssl_android.sh
# for Apple OS family
./build_openssl_apple.sh
```
For Android development, just open the root project as Android Studio project, then you can run and debug it.
For Apple OS family, run `./build_apple.sh` to build the xcframework.
