TypeError:null不是对象(正在评估“WebRTCModule.peerConnectionInit”)

react-native-webrtc webrtc

嘿,伙计们,我有一段时间被这个webrtc的东西卡住了

在弹出的expo应用程序中尝试获取对等连接时,我遇到以下错误:

基于这个博客,我在android清单中添加了以下权限: https://github.com/react-native-webrtc/react-native-webrtc/blob/master/Documentation/AndroidInstallation.md

  <uses-feature android:name="android.hardware.audio.output" />
  <uses-feature android:name="android.hardware.microphone" />
  <uses-permission android:name="android.permission.RECORD_AUDIO" />
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
  <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
  <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
  <uses-permission android:name="android.permission.INTERNET" />

我的代码很简单,即使我也能理解,但我不知道它为什么坏了。

import {
    ScreenCapturePickerView,
    RTCPeerConnection,
    RTCIceCandidate,
    RTCSessionDescription,
    RTCView,
    MediaStream,
    MediaStreamTrack,
    mediaDevices,
    registerGlobals
} from 'react-native-webrtc';


export const createMyPeerConnection = () => {
    var peerConnection = null;

    let peerConstraints = {
            iceServers: [
                {
                    urls: 'stun:stun.l.google.com:19302'
                }
            ]
        };
        
        peerConnection = new RTCPeerConnection(peerConstraints);
}

我查看了一些现有的答案,但它们没有帮助: React Native: Error [TypeError: null is not an object (evaluating 'WebRTCModule.peerConnectionInit')]
