推荐答案

我发现这个一个解决办法。我播放音频文件与完整的声音设备的扬声器的时候，手机状态改变为 TelephonyManager.CALL_STATE_OFFHOOK

I have found a workaround with this. I play an audio file on device's speakers with full sound when the phone state changes to TelephonyManager.CALL_STATE_OFFHOOK

这确保了在另一侧的用户能够听到在记录

This ensures that the user on the other side can hear the recording.
