how can i implement call forwarding in an android app?

推荐答案

呼叫转移是由服务提供者的处理，并不能由手机本身。完成

Call forwarding is handled by the service provider and can't be done by the phone itself.

在你的提供商路由呼叫到您的手机，这是不可能的告诉的提供者编程重新路由到其它地方。这不是Android系统的限制，它只是如何电话网络的工作原理。

Once your provider has routed a call to your phone, it is not possible to 'tell' the provider programatically to re-route it elsewhere. This is not a limitation of Android, it's simply how phone networking works.
