问题描述
我正在尝试使用可以拨打USSD代码的启动器来设计应用程序.当我从设备上运行应用程序时，收到一条错误消息，指出只能从设备的键盘上拨打服务代码.
我正在使用此代码:
I''m trying to design an application using a launcher that can dial USSD codes. When i run the application from the device, i get an error message stating that service codes can only be dialed from the device''s keypad.
Im using this code:
PhoneCallTask ussd = new PhoneCallTask();
ussd.PhoneNumber = "*111#";
ussd.DisplayName = "Service Info";
ussd.Show();
拨打usdd号码，然后返回菜单，该怎么做.但是不会拨号.
有人知道解决方案吗?
奇怪的是，您可以在联系人中保存USSD(例如* 111#)，然后从那里进行拨号，而无需使用键盘输入数字.
What this should be doing it dialing the ussd number and then returning a menu. But it wont dial.
Does anyone know a solution for this?
The odd thing is that you are able to save a USSD (for example *111#) in your contacts and then dial from there without having to type the number using the keypad.
