我正在尝试使用 Android 的 ConnectionService 创建一个呼叫应用程序。我可以成功接听电话，但我试图通过 TelecomManager.addNewIncomingCall 中的“extras”参数传递应用程序特定的数据。但是，当我在 ConnectionService 类中实际创建 Connection 对象时，我找不到访问我设置和传入的 Bundle 的位置。
当我检查 onCreateIncomingConnection(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) 中的传入参数时，connectionManagerPhoneAccount.getExtras() 或 request.getExtras() 都不是我传递给 TelecomManager.addNewIncomingCall 的额外参数。
有没有人在将它传递给 TelecomManager.addNewIncomingCall 后设置和检索这个额外的对象？
我正在尝试将呼叫的电话号码传递给 Connection 对象，以便我可以正确解析来自设备联系人的呼叫者 ID 并显示它。
