AppRTC Android demo

AppRTC demo application with Callstats.io android library integration

Getting Started

These instructions will help you run the apprtc android demo application with callstats integration. See notes on how you will get callstats library related credentials to run the application.

Without the callstats credentials the application will not run.

Prerequisites

• Minimum SDK version 21
• Library dependency
  • WebRTC native
  • Callstats.io android
  • Autobanh websocket
  • JSON WebToken
  • Spongy castle
  • EventBus

Provide credentials

• Get callstats application id, key id, and token. You can hardcoded the token, or use third party server to generate the token and authentication. More details of authentication related integration can be found https://www.callstats.io/blog/2016/09/29/3rd-party-auth-jwt-tokens

  • Apply changes in CsioSHIM.java

    $ Example

Build and run the android application

• In the apprtc demo application give some room name ( for example csio-test-1234 ), and dial
• Open browser, and try to join the same room from here - https://appr.tc/
• Watch your android logcat for sample events
• Or Check your Callstats.io dashboard for given WebRTC sessions

Events implemented in demo

• Look into CSIOEvents.java class for sample events integration in the demo application. Please note that not all the events mentioned in https://docs.callstats.io/restapi/ is implemented. Check the library document for further reference.
• Sample events covered in demo app :
  • Febric setup event
    • Fabric setup - Should call before create and answer or offer
    • Fabric hold, and resume
  • ICE events
    • ICE connection, gathering, signaling change
  • Media Events
    • Mutes/unmutes
    • Video play/pause
  • Special Event - application log
    • Application specific log. Can be anything that you find should be important for your application
    • Example - Toggle between front/rear camera, when user connected/disconnected/join/leave apprtc room, etc.

Integration process

1. Get Callstats.io WebRTC analytic library for android from https://github.com/callstats-io/callstats-android. It also includes the documentation on how we can integrate the library with any WebRTC application along with an integration with callstats own demo application.

2. Include it in your gradle dependency. The apprtc demo is using 0.1.1 version.

   implementation "io.callstats:callstats:<version>"
   

   $ Example

3. Include Google WebRTC prebuild library from JCenter. https://webrtc.org/native-code/android/. The apprtc demo is using 1.0.25003 version

   implementation 'org.webrtc:google-webrtc:<version>'
   

   $ Example

4. [ Optional ] Include EventBus. We are using 3.1.1 version

   implementation 'org.greenrobot:eventbus:<version>'
   

   $ Example

5. Create Callstats object

   callstats = new Callstats(
       context,
       appID, // Application ID from Callstats
       localID, // current user ID
       deviceID, // unique device ID
       jwt, // jwt from server for authentication
       alias, // user alias
       clientVersion, // user version
       callstatsConfig) // Callstats config parameter 
   

   $ Example

6. Start callstats session with a unique identifier. For appRTC session monitoring demo we are using appRTC room number as unique identifier

   callstats.startSession(room)
   

   $ Example

7. Initiate fabric setup event. After fabric setup is complete, we will be able to send data

   // peerConnection - of type WebRTC peer connection
   // peerId - of type string - application specifc identifier for this peer connection
   callstats.addNewFabric(peerConnection, peerId)
   

   $ Example

8. Try to send some data to AppRTC session data. For example -

   • WebRTC ICE Connection state change

     callstats.reportEvent(peerId, new OnIceConnectionChange(newState))
     

     $ Example

   • WebRTC ICE gathering state change

     callstats.reportEvent(peerId, new OnIceGatheringChange(newState))
     

     $ Example

   • WebRTC Signaling state change

     callstats.reportEvent(peerId, new OnSignalingChange(newState))
     

     $ Example

   • On Add new stream

     callstats.reportEvent(peerId, OnAddStream.INSTANCE);
     

     $ Example

   • On audio mute, and unmute

     callstats.reportEvent(peerId, new OnAudio(isMuted, deviceId))
     

     $ Example

   • On video play, and pause

     callstats.reportEvent(peerId, new OnVideo(isPaused, deviceId))
     

     $ Example

   • On fabric hold

     callstats.reportEvent(peerId, OnHold.INSTANCE);
     

     $ Example

   • On fabric resume

     callstats.reportEvent(peerId, OnResume.INSTANCE);
     

     $ Example

   • To send custom message

     // message - of type string
     // level - of type io.callstats.LoggingLevel
     // loggingType - of type io.callstats.LoggingType
     callstats.log(message, level, loggingType);
     
     

     $ Example

9. When a AppRTC peer connection session ends, stop the session monitoring

   callstats.stopSession()
   

   $ Example
