I've resolved this problem. 我已经解决了这个问题。 AudioManager.setSpeakerphoneOn() true then false helped me. AudioManager.setSpeakerphoneOn（）true，然后false帮助了我。 Thanks to all. 谢谢大家。

From what I understand, this is possible on some phones, but the general answer is that you can't record calls. 据我了解，这在某些电话上是可以实现的，但通常的答案是您无法录制电话。 The streams for voice are in a lower level of the operating system and aren't accessible on the "application level". 语音流位于操作系统的较低级别，在“应用程序级别”上不可访问。

Plus it is illegal unless you follow some very strict guidelines, see the link. 另外，除非您遵循一些非常严格的准则，否则它是非法的，请参阅链接。
