我使用意向意图=新的意图（Intent.ACTION_CALL）; 来使从我的应用程序调用

有没有什么办法来终止一段时间后的电话吗？或者，它开始前设置ACTION_CALL定时器吗？

我使用的Prasanta的博客下面code，但由于某些原因上下文越来越下面的错误。有什么建议？

解决方案

您的问题已经被问了很多次。简短的回答是，没有正式的方式来做到这一点。

长回答：

认真阅读。寻找那里有人说，案件用来工作......。

在有人提出要打开飞行模式的问题之一（应用程序需要的权限做的当然是，）。这是粗糙，但它的工作原理。作为一个用户，我将有大约一个应用程序有所保留这样做，虽然。

I am using Intent intent = new Intent(Intent.ACTION_CALL); to make a call from my application.

is there any way to terminate the call after a period of time? Or set a timer for ACTION_CALL before it starts?

I am using the below code from Prasanta's Blog, but for some reason context is getting the error below. Any suggestions?

Your question has been asked a number of times. The short answer is that there is no official way to do that.

The long answers:

Read them carefully. Look for the cases where someone says "used to work...".

In one of the questions someone proposed to turn on airplane mode (the app need permissions to do that, of course). It's crude, but it works. As a user, I would have some reservations about an app doing that, though.
