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.

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!
