webrtc-android-codelab's Introduction

Update

As many might have noticed, I haven't been updating this codelab. It has been some time since I worked with WebRTC but it is in my to-do list to get this updated with as much information as possible. For now, I assume this is broken. PRs are welcome until I get the time to fix it myself. I am pretty sure the Signaling and ICE Servers are not working anymore. For ICE, I used a service - Xirsys which changed their APIs and pricing structure. You would have to look for alternatives (or install Coturn on an AWS instance to run the TURN servers yourself). For Signaling, it is not meant to be production ready. It requires a lot of changes to make it work.

I would recommend looking at https://webrtc.org/getting-started/firebase-rtc-codelab for using Firebase for signalling. I intend on getting the following done

Make change to the app code so that it uses Firebase for signalling and that would mean you can use Firebase RTC Codelab above to get the web component
Try to create a multi-peer mesh network (smaller group calls without the need for a media server)
Screen sharing support for mobiles

I don't have a timeline on when I can get to these. If someone wants to collaborate with me on this, I would love to see some PRs.

Thank you for the support!

Setup Instructions

The test setup contains of three components:

Signaling server
WebRTC Android App
WebRTC example web site

Important: The IP address of the signaling server is hardcoded to 192.168.178.207 and need to be changed in files SignallingClient.java and main.js.

Build Android App Client

"Open an existing Android Studio project"
Select the Step-3 folder
On "Unable to get Gradle wrapper properties from:" click "Ok" to recreate gradle files
Ignore/Cancel all git related questions
Agree to update Gradle
Now a warning appears, agree to "Remove Build Tools version and sync project"
Select "Files" "Sync Project with Gradle Files"
Building and installing the App should work at this point

Start Signaling Server

The signaling server works uses npm and nodejs:

cd signalling
npm install
node index.js

The last command start the signalling server.

Start Web Client

cd signalling
python3 -m http.server

Now open http://localhost:8000 in the browser. You can use a different web server as the python buildin, of course.

How to enable HTTPS

Change http to https in signalling/index.js, signalling/js/main.js and Step-3/app/src/main/java/xyz/vivekc/webrtccodelab/SignallingClient.java.

Then create files key.pem and cert.pem (e.g. with openssl) and uncomment the key options in signalling/index.js.

Command to create key.pem and cert.pem:

openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem

webrtc-android-codelab's Issues

I want to add another window when video call is ongoing for seeing my own when video is ongoing what steps I have to do for that?

Video call play remote audio on loudspeaker

Has anyone come work around to this? please share

How do I Mute Microphone ?

I wanted to implement some of the features here, how do I do that

Turn off/mute local microphone
Turn off local video streaming

multi user more then three

how we can observe multiple user and add stream

Connection timeout in socket.io uri

socket = IO.socket("http://192.168.178.207:1794");
socket.connect();

In above issue socket.io not connect it's thrown timeout error

How to run the server which source code in the directory named "signalling"?

I tried use "python -m SimpleHTTPServer 8000", but seems not work.
"code 404, message File not found"
""GET /socket.io/?EIO=3&transport=polling HTTP/1.1" 404 -"

Step3 is not working.

I have run the step3 application on Chrome Browser and Android app. Localvideo is working and remote video is not working.... what I missed?

how to increase the room size

can you please provide code to increase the room size

can't receive remote stream

Hello, I've implemented step 3. Oddly, I could receive the remote video/sound stream only once.

I get the ice servers
I set up my socket.io server properly and it communicates with my app properly.
the first user creates the room successfully
the second user joins the room successfully.

But in the end, the remote video does not appear, only the local one.

Did anybody experience this?

Thanks

Failed to resolve: :libwebrtc:

I am getting an error when i synced the project.

Step 2 - need to be updated

Step 2 nedds to be updated because I have problems to get the video preview.
Im using the version 11–8–2017 specified in step 1(19324.aar)
in MainActivity, you use
VideoCapturerAndroid.create(name, eventsHandler)
but in the mentioned webrtc version, this class was removed

I tried to put the method from step 1 but the preview still show black screen

Regards

livecast streaming

I am new to webrtc and i want to ask:
How can i make livecast streaming ?, means one device(sender) will broadcast and the others(receiver) will watch it.

Any one have simple guide to achieve it or from where can I start?

JNI DETECTED ERROR IN APPLICATION: can't call java.util.List org.webrtc.MediaConstraints

When I running app and try to open another app on same room and same URI I have message: join to room on first app running . But after that maked crashing with this error
JNI DETECTED ERROR IN APPLICATION: can't call java.util.List org.webrtc.MediaConstraints
Is it related to the number of ICE servers as mentioned here https://stackoverflow.com/questions/41788702/android-webrtc-jni-error-app-bug-local-reference-table-overflow-max-512

Step-1: SurfaceViewRenderer cannot be converted to Callbacks

Hello, I am doing the very first step but I met a problem in the last line of code in MainActivity:

localVideoTrack.addRenderer(new VideoRenderer(videoView));

Is this connected with the library which I use? I got it from here:
implementation 'org.webrtc:google-webrtc:1.0.23171'

How to generate key.pem??

When I run signalling project on node js I have this error

I try to use https://www.npmjs.com/package/pem but I did not solve the problem
How to generate key??

How to implement only Voice call

First of all Thx for such great step wise sample.
I need to implement only voice call . I have successfully runs the demo you provided .
But i am unable to implement only Voice calls. Do we need VideoRenderer and SurfaceViewRenderer to create voice only call ? Please provide a solution . I m currently following Step3 Thx

` localPeer = peerConnectionFactory.createPeerConnection(rtcConfig, new CustomPeerConnectionObserver("localPeerCreation") {
@OverRide
public void onIceCandidate(IceCandidate iceCandidate) {
super.onIceCandidate(iceCandidate);
onIceCandidateReceived(iceCandidate);
}

        @Override
        public void onAddStream(MediaStream mediaStream) {
            super.onAddStream(mediaStream);
            if(mediaStream.audioTracks.size() > 0) {
                remoteAudioTrack = mediaStream.audioTracks.get(0);
                remoteAudioTrack.setEnabled(true);
            }
        }
    });`

I am receiving the remoteAudioTrack but how to use it ?

Video freezes after 1 frame on Android

Hi,
Great codelab.
If I use web & android - it works. both direction - audio & video.
if I try to get 2 android devices on the same WIFI - the remote video stops rendering video and goes black after 1 frame.
Audio sometimes continues, video sometimes return in low resolution when the Ice negotiation restarted somehow - any ideas?
Here is the log compare from the 2 configurations.
https://www.diffchecker.com/bPAi8QMK

Here is the gotRemotestream code
remotevideoTrack = stream.videoTracks.get(0);
runOnUiThread(() -> {
try {
remoteVideoView.setVisibility(View.VISIBLE);
remotevideoTrack.addSink(remoteVideoView);
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG,"gotRemoteStream::"+ e.toString());
}
});

Also - the ice negotiation fails

I have tried many combinations of the code - nothing changed the end result.
Thanks,

Even if the activity, which contains the local_gl_surface_view, is destroyed the "I/org.webrtc.Logging" still keeps logging until that activity is created again or the application is altogether closed.

I have released the local_gl_surface_view in onDestroy(). If I don't then the message in the logs changes from:
I/org.webrtc.Logging: EglRenderer: local_gl_surface_viewDropping frame - Not initialized or already released.
to:
I/org.webrtc.Logging: EglRenderer: local_gl_surface_viewDropping frame - No surface.

Should I worry about the appearance of the above message in the logs?
If I should, please help me in getting rid of this message.

webrtc works via WiFi but does not work via LTE

Hello!
My problem is that I can't create a successful connection between an Android app (LTE/4G/3G) and a Deskop app written in JavaScript (connected to WiFi).

Where can I get the addresses of STUN/TURN servers and how do I install them in the application.

Thanks.Valeriy

VideoCapturerAndroid is deprecated in webrtc:1.0.22379

Hello,
I was following your code but in that time i figure out that VideoCapturerAndroid is deprecated and in your step-2 you are using library from lib.
in step-1 you show how to capture video ok i agree with you. But if i can't use VideoCapturerAndroid then how i manage events or handle the CustomCameraEventsHandler which implements CameraEventsHandler.
If you figure out any way please share with us.

SIGSEGV in nativeAddLocalStream

I try to built an Android WebRTC application. Currently I'm receiving the this error:

04-10 15:40:13.082 10122-10122/? A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 10122 (...), pid 10122 (...)

and I have no clue why? The weird thing is that I can't really say when and why it started because the app was running flawless before.

I tried to find the error and with the help of some debugging I found out the error originates in

    MediaStream stream = peerConnectionFactory.createLocalMediaStream("102");
    stream.addTrack(localAudioTrack);
    stream.addTrack(localVideoTrack);
    localPeer.addStream(stream);

where localPeer is my local PeerConnection.

Does anybody have any idea how to solve this?

The whole stacktrace is:

Audio call

Hi vivek, i am new to webrtc and want to make audio call with help of webrtc( no need of video) , is it possible ??

if yes, then can you please guide me or put sample code for establish audio call ?? @vivek1794

Vivek! Does not work!

Hello, my android app shows me, the browser shows me, but the data is not exchanged. It is not working, spent all day, but it does not work. What is the problem?

key.pem not found in signalling project

When i want to run this code i found a error that is key.pem is not found.
Can you share this with us.

Null pointer error in doCall();

i am getting error in doCall();

private void doCall() {
localPeer.createOffer(new CustomSdpObserver("localCreateOffer") {
@OverRide
public void onCreateSuccess(SessionDescription sessionDescription) {
super.onCreateSuccess(sessionDescription);
localPeer.setLocalDescription(new CustomSdpObserver("localSetLocalDesc"), sessionDescription);
Log.d("onCreateSuccess", "SignallingClient emit ");
SignallingClient.getInstance().emitMessage(sessionDescription);
}
}, sdpConstraints);
}

JNI DETECTED ERROR IN APPLICATION: can't call java.util.List org.webrtc.MediaConstraints.getMandatory() on null object.

I think sdpConstraints is null so getting this error, any solution for this? @vivek1794

Error in MainActivity --> getIceServers()

I am getting error in MainActivity.java --> getIceServers() --> for (IceServer iceServer : iceServers)

: java.lang.NullPointerException: Attempt to invoke interface method 'java.util.Iterator java.util.List.iterator()' on a null object reference

For this i think i need to change para in TurnServer.java interface ,
in this interface , request url is there and for that i signed up in xirsys to get new values of param from my account.

from Xirsys account i got detail : ident,secret,channel,secure.

what should i pass in : domain,application,room??

Signalling server error

Problem 1:
Cannot show streams correctly.
Solution:
Change all xxx.src = window.URL.createObjectURL(stream) to xxx.srcObject = stream;

Problem 2:
Cannot send streams correctly.
Solution:
Fix the typo RTCSsseionDescription -> RTCSessionDescription in signalling/js/main.js line 83

Invalid MediaConstraints

Hello,
I followed your code from github, everything is working fine but when i'm passing new MediaContraints() in pc.createAnswer().... pc.setLocalDescription() method was not called. But when i'm passing constraints like "offerToRecieveAudio" and "video" is true, giving error like invalid Constrains.

Could you help me out.

Thanks.

getting onfailure() in getIceServers() method.

Hi,

I'm a beginner of webrtc and trying to review your examples. I tried to get Ice server from xirsys with my info...but failed.
Could you please review my code?
I also tried to get ice server without "<>" in codes....also met exception...please help.

Screeching sound in remote audio. It is barely audible

@vivek1794
Hi I know it might be out of scope for this repository but I have been searching for the solutions for past three weeks I have asked question on stack also Qus but no answer from there also. Please let me know if you know any way to disable amount of noises and screeching sound.
I am properly initializing audio constraints

audioConstraints.mandatory.add(new MediaConstraints.KeyValuePair("googNoiseSuppression", "true"));
audioConstraints.mandatory.add(new MediaConstraints.KeyValuePair("googEchoCancellation", "true"));
audioConstraints.mandatory.add(new MediaConstraints.KeyValuePair("echoCancellation", "true"));
audioConstraints.mandatory.add(new MediaConstraints.KeyValuePair("noiseSuppression", "true"));```

but still it does not work.

signalling client always disconnect after a few minutes.

I have run STEP-3 project on my Android Phone and it is getting disconnect continuously after a few minutes.
what issue is it?

session terminates while a new communication started

we are tried to implement connection between A and B it works while we tried to connect C and D via a different room session terminates for A and B and connection closed , can you please provide a solution for this

How to Run the Android Application ?

Hello,
Thanks for the demo. Can someone please tell me how to run & test this application? I've imported Step-3 on AndroidStudio & successfully run the application (on two devices). But after opening the app (granting Camera & Microphone permission), nothing happen.

I've run the signalling server using node index.js command. After opening the local host (https://localhost:1794/), a prompt opens to insert room name (say "class"). After pressing the OK button, it redirects me to another page where I can see my preview.

Please note that, on my Android Project, at SignallingClient class, I set

instance.roomName = "class";
socket = IO.socket("https://localhost:1794/");

but I can't make any call. Can someone please help me? Thanks.
