ByteBuffer byteBuffer = ByteBuffer.wrap(convertFileToByteArray(file)); DataChannel.Buffer buf = new DataChannel.Buffer(byteBuffer, isBinaryFile); dataChannel.send(buf); On the other side, this callback should be called regardless of isBinaryFile value : public void onMessage( final DataChannel.Buffer buffer ){ Log.e(TAG, "Incomming file on DataChannel");

The intent is for this to become a Community Wiki post that is kept up-to-date so developers interested in implementing communication of JSON messages browser-to-browser (p2p) with WebRTC DataChannels have simple yet functional examples. WebRTC DataChannels are experimental and still in draft. It seems that currently the web is a minefield of outdated WebRTC examples and even more so if a developer is trying to learn the RTCDataChannel API. Simple yet functional 1-page examples that work today across WebRTC compliant browsers seem very difficult to find. For example, some examples leave out a
