获取“<app_name> 无法拨打电话尝试使用其他呼叫重定向应用程序或联系开发人员寻求帮助”拨号时

问题描述

我正在构建一个默认的来电显示和垃圾邮件发送者应用程序，它将检索一个号码的来电详细信息并通过电话拦截详细信息。我使用的是 Android 10.0，不知道此代码如何在其他版本的 Android 上运行。安装应用程序后，我无法拨打任何外拨号码。我收到此错误消息：

Call can't be placed by <appname>. Try using a different call redirecting app or contacting the developer for help.

谁能告诉我如何解决这个问题？
