Here is what I see.

In AudioRecord.h and in the MediaRecorder.AudioSource, the enum values differ.

In native code (AudioRecord.h), the values are ..
44     enum input_source {
45         DEFAULT_INPUT   =-1,
46         MIC_INPUT       = 0,
47         VOICE_UPLINK_INPUT = 1,
48         VOICE_DOWNLINK_INPUT = 2,
49         VOICE_CALL_INPUT = 3,
50         NUM_INPUT_SOURCES
51     };

In Java MediaRecorder AudioSource, the values are ..
120     public final class AudioSource {
121       /* Do not change these values without updating their counterparts
122        * in include/media/mediarecorder.h!
123        */
124         private AudioSource() {}
125         public static final int DEFAULT = 0;
126         /** Microphone audio source */
127         public static final int MIC = 1;
128
129         /** Voice call uplink (Tx) audio source */
130         public static final int VOICE_UPLINK = 2;
131
132         /** Voice call downlink (Rx) audio source */
133         public static final int VOICE_DOWNLINK = 3;
134
135         /** Voice call uplink + downlink audio source */
136         public static final int VOICE_CALL = 4;
137     }

Now, if you look at AudioFlinger, any input source, whose value of stream type is >=
NUM_INPUT_SOURCES (i.e., 4), we will get an "invalid stream type". Because of the
mismatch of the enums, the Java API sets the value of VOICE_CALL stream type as 4.
So, the check fails and we get the failure.

http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=libs/audioflinger/AudioFlinger.cpp;h=da7cc8a6aa62a9d66097a6d9c7c184d132df7c3d;hb=donut#l2245

Fix:
Set the values of the stream types to be the same in the Java and c++ code.

Hope this helps.

i have Put in Manual Settings for Call Recorder Source as 0,1,2 and 3 All these
Settings only Records Voice Stream from MIC only there is no Such VoiceCall,
VoiceCall Incomming and Outgoing.

I think Google have missed some file to Support it Actual

use vrecorder

android.media.MediaRecorder.AudioSource.VOICE_DOWNLINK  ;
android.media.MediaRecorder.AudioSource.VOICE_UPLINK  ;
These two option do not work!
Whatever I set it to VOICE_DOWNLINK,VOICE_UPLINK or VOICE_CALL, the resault is the
same as VOICE_CALL!
Please fix!
Thanks!

I couldn't figure out how to star... But I need to call records because of my
business..

Fix this google you lazy fucks

fix it to beat iphone

LOL! pls fix guys! come on

The issues related to this bug started over a year ago. Google's inability to fix
this bug presents a great opportunity for competitors to show the inferiority of
Google's support and community help.

Pls fix. I work in service for homeowners. This would help out for me to remember
appts and also to prove to them they had appointments set. PLSSSSSSS fix!!

This is such an important feature. I have been receiving several threats and if this worked then i would be able to get a restraining order, however its broke so i cant. I use a Motorola Droid

It doesn't work in Android 2.1.

Eric Raymond has been doing a good job of selling the Android (Nexus1, etc)  But this is an essential feature.  Without it, I might as well use Symbian S60; they are Open Source now too.  I'll hold out a little while longer for this, but not much.

Seems like this should be fixed.

Something new in Android 2.2 , are there 3 options work now ?

Tried in Froyo (2.2) and the VOICE_DOWNLINK option still records from the MIC, even when you are on a phone call.  So it still does not work, and there seems to be no way to record the voice stream during a call.

I hate to admit it but android is starting to disappoint me. :-(
Maybe I must swallow my pride and become a iphone user since I see this as a requirement for a phone

This issue started almost a year ago and still marked as New. Seems like ignored by developers..
