I have been trying to stream an on-device audio file to an incoming call, I am not able to achieve that.
(我一直试图将设备上的音频文件流式传输到来电，但我无法实现。)
but it looks google call screen is having no problem streaming audio to an incoming call. (但看起来Google通话屏幕没有问题，无法将音频流式传输到来电。)
I just wanted to understand how are they achieving that, if it is fundamentally not possible?
(我只是想了解，如果根本上不可能，他们将如何实现这一目标？)
