使用Android框架这可能吗？的目的是为了在调用听到音频的另一端的人

Is this possible using the Android framework? The goal is for the person on the other end of the call to hear the audio.

如果这是不可能的，它是一个硬件限制或Android框架的限制吗？

If it's not possible, is it a hardware limitation or a limit of the Android framework?

推荐答案

我相信你能不能做到这一点，根据文档的 这里 ：

I believe that you cannot achieve that, according to the documentation HERE :

请注意：您可以播放音频数据只到标准输出设备。   目前，这是在移动设备的扬声器或一蓝牙耳机。   在通话过程中无法播放的谈话音频声音文件。

Note: You can play back the audio data only to the standard output device. Currently, that is the mobile device speaker or a Bluetooth headset. You cannot play sound files in the conversation audio during a call.
