交互式ussd会话（多步骤）在android 8（Oreo）上不起作用

我目前正在使用android api level 26（Nexus 6P）中提供的电话管理器（USSD response）。对于单步ussd会话，它是有效的

参考：

例如：

USSD请求：“A”（USSD会话启动）

USSD响应：“X”（USSD会话终止）

但对于交互式ussd请求响应（多步骤），它不起作用。 多步骤场景如下所示：

第1步

USSD请求：“A”（USSD会话启动）

USSD回应：“X”

第二步

USSD请求：“B”（USSD会议继续）

USSD回应：“Y”

第三步

USSD请求：“C”

---

USSD响应：“Z”（USSD会话终止）

通过使用反射，我设法绕过了一些问题（如多会话USSD响应不工作）。我做了一个GitHub要点

显然，我们的假设是，给出了正确的权限（此时只有

CALL\u PHONE

）——就上下文而言，我只在活动中运行过此功能，但我认为它在大多数情况下（如果不是全部/任何情况下）都可以正常工作

---

下一件事是找出如何维持会话，如果可能的话。

我可以得到一个菜单，通过发送一个数字来响应它，但如果超过了这个数字，我想是由电信公司决定的-他们发送的菜单会阻塞整个屏幕，如果你取消它，整个会话就会消失。在电信行业工作过，我认为这可能与电信公司不同，因为其中一些公司有网关，可以终止用户发起的会话，并用电信端发起的会话替换它。从技术上讲，这两个会话是分离的。但这是我的代码：

如果您使用双sim卡，请确保更改您要测试的网络（在我使用的Airtel（*121#）不幸的是，谷歌在Oreo中添加的API仅适用于USSD服务，在该服务中，您可以在开始时拨打整个USSD代码，并在会话中无需输入任何内容即可获得响应。他们显然没有意识到的是，大多数电信公司出于安全原因，特别是在有PIN输入的情况下，会阻止这种做法f该API实际上似乎是为了处理进一步响应的情况，但正如各种海报所指出的，即使在Android 10上，它实际上也不起作用

我的公司开发了一个Android SDK，它使用可访问性服务来运行多步骤USSD会话，并让它出现在你的应用程序中。你为USSD服务创建配置，触发会话从你的应用程序运行，并传入你需要的任何运行时变量。用户从未看到USSD会话，并且当响应为r时eturned您的应用程序会收到通知，您可以根据需要对其进行解析。它适用于Android 4.3及更高版本

SDK是免费集成和使用的，直到你达到大规模。请参阅我们的开始

（披露：我是Hover的首席技术官）

你好。我现在也遇到了同样的问题。你是如何解决你的问题的？除此之外，我只得到了错误代码-1…直到现在我还没有找到任何解决方案。很高兴你回答了我，我忘记了我对这篇文章的评论…实际上我甚至没有正确阅读你的文章…因为我尝试了多步USSD，它失败了。我求助于单步USSD。N对于multistep，可能您需要覆盖

sendusdrequest

中的某些内容。我发现有一种类似于

onreceivesult

的方法，它可以捕获多步骤的消息，但它不知道如何继续处理请求……现在就忘记多步骤，或者将其集成到您的UI中……我知道了我发现了另一种解决方案，使用android易访问性服务接收USSD响应并给出input@zoraf你能分享这个替代解决方案的链接吗？有没有比USSDresponseCallback的26个更具向后兼容性的解决方案呢？这很遗憾。有时候运营商不提供直接的方式来访问你的互联网计划或其他，只有一个连续的菜单。API实际上是为了处理这个问题而设计的-这就是为什么它将处理程序作为参数。为什么它实际上不处理它是另一个问题…包含处理程序并不意味着API是为了处理基于菜单的USSD而设计的；它只是为调用者提供了一种方法来确保callback操作被发布到他们选择的处理程序。干得好，我们需要更多像你这样的人！在你的示例中，

l

在

newresultreceiver（l）中指的是什么{

？@Razgriz它指的是我在上下文中拥有的一些

处理程序

类型的对象，通常是主UI线程处理程序。因此，要实例化一个，可以这样做：

Handler l=new Handler（Looper.getMainLooper（））

如果您已经在主UI线程中执行，那么您可以省略对主循环器的引用，只使用

新处理程序（）；

。关于这一点有什么建议吗？我无法获得handleUssdRequest方法！@Abdu您是否能够提取

HandleusDreQuest

？@real\u shardul否“SDK可以免费集成和使用，直到您实现大规模应用。”。我可以在您的定价页面上看到（）免费计划中没有提到最大请求数。你能澄清一下吗？嘿@davkutalek有没有办法关闭屏幕上显示动作名称和插入方法extra的数据的自定义内容？@vkamme
