Android 如何在其他呼叫运行时以编程方式合并呼叫（会议呼叫）
我的要求是这样的：假设我当时正在拨打一个号码，我想通过编程方式拨打另一个号码。到目前为止，我所做的是：当某个电话已经接通时，我能够拨打某个特定的号码。例如，假设我正在呼叫号码123，1分钟后（通过使用Android 如何在其他呼叫运行时以编程方式合并呼叫（会议呼叫）,android,api,merge,Android,Api,Merge,我的要求是这样的：假设我当时正在拨打一个号码，我想通过编程方式拨打另一个号码。到目前为止，我所做的是：当某个电话已经接通时，我能够拨打某个特定的号码。例如，假设我正在呼叫号码123，1分钟后（通过使用报警管理器），我触发一个事件来呼叫另一个号码456，这就完成了 Intent intent = new Intent(Intent.ACTION_CALL); intent.setData(Uri.parse("tel:456")); startActivity(intent); 我正在使用这种意
报警管理器Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:456"));
startActivity(intent);
在此图像中，您可以看到一个合并调用的按钮。现在，当用户单击“合并”时，它将合并所有3个调用。我希望以编程方式进行合并，而不是使用用户界面。Android API不支持调用合并功能。您可以看到此线程。 $20call/android开发者/6OXDEe0tCks/8cuKdW1J9b8J
但是，您可以使用aidl打开手机的呼叫板屏幕，用户可以从中添加另一个呼叫或合并呼叫。您无法使用智能手机管理会议。您需要一个可以为您实现这一点的中间服务。您可以使用 Voxeo为CCXML实现提供了一个良好的托管平台，您可以查看他们关于如何设置会议的介绍。在“学习CCXML 1.0\CCXML 1.0中的多方会议”中有一些示例 你可以在Voxeo上免费开发和测试，只有在你投入生产后，他们才会开始向你收费。另一个选择是Twillio 这里有一个链接
检查链接，您将获得有用的信息。#礼貌-因此Afaik，SDK中没有以编程方式进行合并调用的API 对于android用于电话呼叫的呼叫会议，您必须使用
RIL（无线接口层）因此，您必须在套接字中写入AT调制解调器命令，然后调用对供应商库的回调，然后供应商库依次委托无线电固件。您的问题似乎很有趣，因此我开始挖掘Android源代码。以下是我发现的： 您发布的图片中的活动称为 当您开始环顾四周时，您会发现第463行中有：
final boolean canMerge = activeCall.can(Capabilities.MERGE_CALLS);
CallCommandClient.getInstance().merge();
我列出的API大部分都是Android内部的东西。您可能需要使用反射来调用它，或者根本不可能，因为它没有标记为系统应用，所以对您的应用程序来说可能无法访问。android中没有用于获取会议呼叫的api，您可能希望使用根系统来完成工作 官方称，android没有为电话会议提供任何api。您可以在这里学习更多有关根访问的内容
经过大量搜索，我成功地合并了呼叫，在此我想与您分享我的发现。 作为参考，我用了这个
我可以打电话给第三方，问题是如何合并，当我们建立第三个电话，而此时已经有两个人在通话，合并选项出现在电话屏幕上，我不希望用户点击合并按钮并建立电话会议，我想通过编程将其合并我不太确定，但你可以通过performClick（）方法实际调用事件，但你必须在上面搜索ID这是我能做的事情，正如我在信中提到的question@Williams谢谢你的批评。我真诚地接受你的想法，但我只是说它在Android API中不可用，不适用于所有的东西。我也想知道哪个应用程序的名称也一样。这是一个系统应用程序吗？很酷，但需要检查它是否适用于Android手机，如果您发现任何解决方案、任何文章或其他与此相关的内容，请与我们分享。您所在国家的运营商是否支持GSM电话会议？@user755当然可以。这里是yescheck。。嘿，伙计，你怎么打第二个电话的？如果我从AlarmManager尝试startActivity，它将等待呼叫断开，然后它将拨打。。。你能和我们分享你的代码吗？我是按照你的代码来做的，但是我得到了ClassNotFound
