使用telecomManager和我们的自定义协议

问题描述 投票:1回答:1

我正在尝试使用本指南实现与电信服务的互连:https://developer.android.com/guide/topics/connectivity/telecom/

我已经可以在没有电信服务的情况下显示我自己的全屏来电UI,拨打和接听视频电话。所有我想与Telecomservice合作,只是告诉Android操作系统,我们的应用程序在特定时刻启动/停止视频通话,并接收来自其他通话应用程序的来电保留/非保留事件。

主要问题是:

1)addNewIncomingCall在传入调用的情况下什么都不做:onCreateIncomingConnection回调没有被触发(甚至onCreate回调我的ConnectionService根本没有被触发)。为什么没有启动连接服务?

2)在拨打电话的情况下,呼叫尝试用我们的用户ID打开系统呼叫应用,将其称为电话或SIP号码。我可以在没有系统UI的情况下使用placeCall吗?

或者,如果我只想通知系统有关视频通话的问题,我可以使用除TelecomService之外的其他选项吗?

连接创建如下:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        connection?.connectionProperties = Connection.PROPERTY_SELF_MANAGED
    }
    connection?.connectionCapabilities = Connection.CAPABILITY_HOLD and Connection.CAPABILITY_SUPPORT_HOLD
    connection?.setVideoState(VideoProfile.STATE_BIDIRECTIONAL)

拨打电话:

val telecomService = context.getSystemService(Context.TELECOM_SERVICE) as TelecomManager
                    try {
                        val uri = Uri.fromParts(PhoneAccount.SCHEME_SIP, teacherInfo.name, null)
                        telecomService.placeCall(uri, Bundle.EMPTY)
                    } catch (e: Throwable) {
                        e.printStackTrace()
                    }

接听电话:

val telecomService = applicationContext.getSystemService(Context.TELECOM_SERVICE) as TelecomManager
                      try {
                          Log.d("VideoCOnnection", "addNewIncomingCall")
                          telecomService.addNewIncomingCall(CallUtils.getAccountConnection(telecomService), Bundle.EMPTY)
                      } catch (e: Throwable) {
                          Log.d("VideoCOnnection", "crash")
                          e.printStackTrace()
                      }


@SuppressLint("MissingPermission")
fun getAccountConnection(teleconManager: TelecomManager) : PhoneAccountHandle? {
    return if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        val enabledAccounts = teleconManager.callCapablePhoneAccounts
        for(account in enabledAccounts) {
            if(account.componentName.className.equals(BindTelecomService::class.java.canonicalName)) {
                return account
            }
        }
        return null
    } else
        null
}

看起来你想用self-managed connection service实现这个应用程序。

检查您是否拥有权限:

  • MANAGE_OWN_CALLS
  • READ_CALL_LOG
  • READ_PHONE_STATE

使用CAPABILITY_SELF_MANAGED注册电话帐户。

final String phoneAccountLabel = "myPhoneApp";

ComponentName connectionServiceName = new ComponentName(context.getApplicationContext(), TcService.class);
accountHandle = new PhoneAccountHandle(connectionServiceName, phoneAccountLabel);

PhoneAccount phoneAccount = telecom.getPhoneAccount(accountHandle);
if (phoneAccount == null) {
    PhoneAccount.Builder builder = PhoneAccount.builder(accountHandle, phoneAccountLabel);
    builder.setCapabilities(PhoneAccount.CAPABILITY_SELF_MANAGED);
    phoneAccount = builder.build();
    telecom.registerPhoneAccount(phoneAccount);
}

添加新的传入或传出呼叫时,必须添加额外的EXTRA_PHONE_ACCOUNT_HANDLE。

Uri uri = generateCallUri();
extras.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, accountHandle);
telecom.addNewIncomingCall(accountHandle, extras);
