android - 我可以将 Web RTC 应用程序注册为调用应用程序吗

Question

I have web rtc implemented in a webview. Everything working fine as long as app in foreground.

现在如果应用程序位于 背景/剂量模式。我要显示 响铃之类的应用程序 .
当有人打电话时，我收到推送通知。
我知道我可以通过调用声音和通知的 onClick 显示通知警报。我可以显示我的应用 Activity 。
是否存在诸如 this 之类的调用 url
可以是未经通知处理
或者我可以将我的应用注册为调用应用。这样每当通话发生时，我都会注册 ConnectionService
并收到onCreateIncomingConnection

Answer 1

是的你可以。我使用 janus 网关，我的代码部分是相应的，

接收firebase消息。

     if(!remoteMessage.getData().containsKey("hangup")){
         print(remoteMessage.getData());
         try {
             Application.shared.pushMessage = new JSONObject(remoteMessage.getData().toString());
             Application.shared.sipClient = new SipPluginHandler(null,true);
             Application.shared.action = "incoming";
         } catch (JSONException e) {
             e.printStackTrace();
         }

     }else{
         Application.shared.action = "hangup";
       //  Application.shared.voipPlugin.endCall(Application.shared.uuid);
       Application.shared.voipPlugin = null;
     }

SipPluginHanler 是我的应用程序连接 websocket 然后初始化 webrtc 并执行发送接收 jsep 操作的地方。

在初始化处理程序并建立 websocket 连接后处理 firebase 消息。

公共(public)无效声明成功(){

    JSONObject msg = new JSONObject();
    JSONObject result = new JSONObject();

    if (fromConnectionService){

        if(Application.shared.action == "incoming"){
            JSONObject message = Application.shared.pushMessage;

            if (message != null){
                putData(result,"event","incomingcall");

                try {
                    String caller =  message.getString("caller_id");
                    putData(result,"username", "sip:" + caller + "@" + connectionInfo.ulakCagriIp);
                    putData(result,"displayname", caller);
                    putData(msg,"janus","event");


                    JSONObject dtdt = new JSONObject();
                    JSONObject dt = new JSONObject();

                    putData(dtdt,"result",result);

                    putData(dt,"data",dtdt);

                   putData(msg,"plugindata",dt);


                    JSONObject extra = message.getJSONObject("extra");

                    if (extra != null){
                        JSONObject jsep = extra.getJSONObject("jsep");
                        putData(msg,"jsep", jsep);

                        JanusMessage mesg = JanusMessage.fromJson(msg);
                       onEvent(mesg);


                    }




                } catch (JSONException e) {
                    e.printStackTrace();
                }



            }





        }else{

            putData(result,"event", "hangup");
            putData(msg,"janus", "event");
            JSONObject dtdt = new JSONObject();
            JSONObject dt = new JSONObject();

            putData(dtdt,"result",result);

            putData(dt,"data",dtdt);

            putData(msg,"plugindata",dt);

            JanusMessage mesg = JanusMessage.fromJson(msg);
            onEvent(mesg);


        }

    }
}

在事件中，有开关盒检查事件是否来自 janus 网关。

 switch (eventType) {
            case accepted:
            updateUI(eventType);
                onAccepted();
                break;
            case calling:
            break;
            case declining:
            break;
            case declined:
               onHangup();
                onDeclined();
                updateUI(eventType);
                break;
            case hangup:
            onHangup();
            updateUI(eventType);

                if (result.code != 0 && (result.code == 486 || result.code == 503) ){
                    incallManager.stop("_DTMF_");
                } else{ incallManager.stop();
                    //incallManagerPlugin.stopRingtone();
                }
            break;
            case incall:
            break;
            case incomingcall:

              onIncomingCall(result);
               updateUI(eventType);
                break;
            case proceeding:
            updateUI(eventType);
                onPorceeding();
                break;
            case progress:
            break;
            case registered:
            onRegistered(message);

                break;
            case registering:
            break;
            case registration_failed:
            break;
            case ringing:
            break;

        }

最后 onIncoming 函数我检查处理程序类 fromConnection 是否为真，然后我调用 ConnectionService。

 private void onIncomingCall(JanusMessage.JanusResult result) 
    {
         Application.shared.text = result.displayname.replace("\"","");

  if(fromConnectionService){
     Application.shared.voipPlugin = new VoipPlugin();

     uuid = createTransactionID();
     Application.shared.uuid = uuid;
    Application.shared.voipPlugin.reportIncomingCall(uuid,Application.shared.text,Application.shared.text);
   }
}

对于连接服务类，我刚刚修改了下面颤振插件的 android 部分。
