Detailed explanation of how uniapp implements phone call recording function (with core code attached)

This article brings you relevant knowledge about uniapp. It mainly introduces how uniapp implements the call recording function. Friends who are interested can take a look below. I hope it will be helpful to everyone.

Recently I need to implement a function of calling a mobile phone through uniapp. After making a call, I will record at the same time. After hanging up the phone, I will upload the recording file. Now I will share some core codes with everyone. I hope it will be helpful to everyone

const recorderManager = uni.getRecorderManager();

onLoad(option) {
            let self = this;
            recorderManager.onStop(function (res) {
                console.log("res",res)
                self.end_time = Math.round(new Date().getTime() / 1000);
                let voicePath = res.tempFilePath;
                self.voicePath = voicePath;
                self.closeTimeOut();

                uni.showToast({
                    icon: 'loading',
                    title: "请稍后...",
                    duration: 0
                });
                uni.uploadFile({
                    url: self.upload_url,
                    filePath: voicePath,
                    name: "file",
                    formData: {
                        id: self.phoneInfo.id,
                        start_time: self.start_time,
                        end_time: self.end_time,
                        phone: self.phoneNumber
                    },
                    header: {
                        Authorization: "Bearer " + uni.getStorageSync(EnumData.token)
                    },
                    success: (res) => {
                        // console.log("文件上传成功")
                        console.log(res.data);
                    },
                    fail(err) {
                        console.log("文件上传失败")
                        console.log(err);
                    },
                    complete() {
                        self.start_time = 0;
                        self.end_time = 0;
                        uni.hideToast();
                    }
                })
            });
            this.getCallStatus();
}

getCallStatus() {
    let that = this;
    let maintest = plus.android.runtimeMainActivity();
    let Contexttest = plus.android.importClass("android.content.Context");
    let telephonyManager = plus.android.importClass("android.telephony.TelephonyManager");
    let telManager = plus.android.runtimeMainActivity().getSystemService(Contexttest.TELEPHONY_SERVICE);
    let receiver = plus.android.implements('io.dcloud.android.content.BroadcastReceiver', {
        onReceive: function (Contexttest, intent) {
            plus.android.importClass(intent);
            let phoneStatus = telManager.getCallState();

            that.callStatus = phoneStatus; //电话状态 0->空闲状态 1->振铃状态 2->通话存在
            switch (phoneStatus) {
                case 0:
                    console.log("3、电话挂断，上传录音")
                    // 结束录音
                    recorderManager.stop();
                    break;
                case 1:
                    // console.log('1、振铃状态');
                    break;
                case 2:
                    console.log('2、通话存在')
                    // 延迟录音
                    that.start_time = Math.round(new Date().getTime() / 1000);
                    recorderManager.start({
                        duration: EnumData.audioDuration, // 时长 10分钟
                        sampleRate: EnumData.audioSampleRate, // 码率
                    });
                    break;
            }
        }
    });

    let IntentFilter = plus.android.importClass('android.content.IntentFilter');
    let filter = new IntentFilter();
    filter.addAction(telephonyManager.ACTION_PHONE_STATE_CHANGED);
    maintest.registerReceiver(receiver, filter);
},

The permissions that need to be applied for can be placed in App.vue

if (plus.os.name == 'Android') {
      plus.android.requestPermissions(
         ['android.permission.ANSWER_PHONE_CALLS',//手动 挂断和接听 需要这个权限
          "android.permission.MODIFY_AUDIO_SETTINGS",//手动 挂断和接听 需要这个权限
          "android.permission.CALL_PHONE",//手动 挂断和接听 需要这个权限
          "android.permission.READ_PHONE_STATE",//>监听电话状态 需要这个权限
          "android.permission.READ_CALL_LOG",//获取号码需要这个权限
          "android.permission.READ_AUDIO" // 录音权限
          ],
      function(resultObj) {
          var result = 0;
          for (var i = 0; i < resultObj.granted.length; i++) {
          var grantedPermission = resultObj.granted[i];
          console.log(&#39;已获取的权限：&#39; + grantedPermission);
          result = 1
      }
      for (var i = 0; i < resultObj.deniedPresent.length; i++) {
          var deniedPresentPermission = resultObj.deniedPresent[i];
          console.log(&#39;拒绝本次申请的权限：&#39; + deniedPresentPermission);
          result = 0
      }
      for (var i = 0; i < resultObj.deniedAlways.length; i++) {
          var deniedAlwaysPermission = resultObj.deniedAlways[i];
          console.log(&#39;永久拒绝申请的权限：&#39; + deniedAlwaysPermission);
          result = -1
      }
     },  function(error) {
          console.log(&#39;申请权限错误：&#39; + error.code + " = " + error.message);
     } );
}

Notes

1. In debugging mode, the call hangup can be monitored normally And I uploaded the file, but it becomes invalid after being packaged?
General mobile phone packaging can be used normally. I use oneplus7. After packaging, it can be installed and used normally. Some mobile phones need to go to the permissions of the system settings and turn on the [Turn on mobile device status code] of the application. This is what I've encountered so far.
