问题描述
使用mediarecorder通话录音，在音频源设置为
Using mediarecorder to record calls, with setting the audio source to
MediaRecorder.AudioSource.VOICE_CALL
MediaRecorder.AudioSource.VOICE_CALL
不会对三星Galaxy S2（Android版2.3.4）工作，在应用程序死机，没有记录被创建（VOICE_UPLINK / VOICE_DOWNLINK都工作，但只记录多达/下行链路，而不是两个方语音）。
does not work on Samsung Galaxy S2 (Android 2.3.4), in the application freezes and no recording is created (VOICE_UPLINK/VOICE_DOWNLINK both work, but only record up/downlink, not both party voice).
但是，例如（从Android Market）的应用CallRecorder没有工作（同时录制声音派对）。所以这是可能的。
However, e.g. the CallRecorder application (from Android Market) does work (recording both party voices). So it's possible.
这是如何做呢？
推荐答案
我想通过 AudioSource.CAMCORDER 在银河S2记录，但我有同样的问题;我没有得到任何样品。其实，我想有两个音频源， .MIC 和 .CAMCORDER ，记录样品分开，但我想，就像汗说， .MIC 可能会工作。
I am trying to record through AudioSource.CAMCORDER on a Galaxy S2, but I have the same issue; I get no samples. Actually, I tried to have two audio sources, .MIC and .CAMCORDER, recording separate samples, but I guess, just like khan said, .MIC will probably work.
