我开始从我的应用程序中的语音呼叫。现在我想，当另一侧的用户拿起电话，我想打一个录制的音频文件。

I am initiating a voice call from my application. Now i want that when the user on the other side picks up the call, i want to play a recorded audio file.

如何着手呢？请帮帮忙！

How to go about this? Please help!

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.
