After a bit of googling I came to know that recording a call in android is not possible maybe because of some legal reasons, But I want to know whether its's possible to stream the call voice from android, I dont't want to record it, just want to tether it for some functionality requirement..
Thanks in advance...

I search about it a lot but got nothing. I just want to know is it possible or not? If yes than how?
No.
The simple fact is the microphone / input audio stream during a phone call is not able to be pre-processed or replaced with another stream of any form.
So simply while one would think its easy to use media during a call, it simply is not possible due to the way the android system processes the audio.
I have following requirements :
When call is received in android phone instead of streaming microphone output I want to stream a recorded audio every time I receive call.
So that it should be like a virtual mic.
Is it possible to do this?
Is there any API/handlers to do it?
Any references?
From what I've seen, there is no dedicated API for this, nor is there any possible way to do this without rooting the Android device, which can be a very long process depending on the device. I don't know much besides that, however, such as how to do this with a rooted device, so you can probably find better explanations of that from another answer or somewhere else online.
i'm trying to develop an application to record calls bothside(mic and speaker). I've seen there is one app vrecorder providing this vrecorder for android 1.6.
Now i want to do this for android 2.2 and above. Can i know is this possible with MediaRecorder.AudioSource.
I've read some forums they are saying that there are some issues on doing this.
In Stackoverflow itself several questions are about record voice calls saying that not posible. But these posts are older. Is it possible to record phone calls via an Android App? .
But http://code.google.com/p/android/issues/detail?id=2117 in this discussion they are saying that some issues are there but we can implement.
Atlast, please I need some descriptive answers, that can we record voice calls in android both way (from mic and speaker).
Thanks in advance.
Call recording is not yet possible on Android. The feature request you are referencing is still not resolved.
People that have been able to do call recording use rooted phones with custom kernel.
On stock Android phones, you can only record your voice from microphone, but you can not record the sound of the other party. If you only want to record your voice use android.media.MediaRecorder.AudioSource.MIC
I like to make an application for recording voice call.Is it possible? I expecting some proper guiding from well experienced people in android.
i have seen android.media.MediaRecorder class in android. Is that class i need to use for this?
Thanks and Regards

Developers do not have access to the in-call audio stream, sorry. The only way this sort of works is if the device is in speakerphone mode.
my app uses the RecognizerIntent to record the user's voice and doing some speech recognition.
Now, I'd like to compare the results to some open source speech recognition engines. Most of them take an audio file as input. My thought was, to capture the sound from the Android's microphone, and start the RecognizerIntent at the same time. But it seems, that accessing the microphone is exclusive.
Is it possible to use the RecognizerIntent with a recorded audio stream?
Is it possible to access the microphone simultaneously with two Activites?
I have tried to find a solution to the same problem and have not had success. One other approach we explored was to access the web service that Google uses for recognition. I posted a question at Google's voice search speech recognition service, but it still goes unanswered.
There was a good post at Voice recognition on android with recorded sound clip? that dealt with this question and I believe the answer came from a Google employee.
Unfortunately the answer to both of your questions is no, but there are plans to extend this for Gingerbread and 3.0: http://www.mobiclue.com/android-3-0-gingerbread-features-supported-phones.html
I know for sure that is possible to use RecognizerIntent and save the audio, the question is how?
You can see in Google Keep Android applications doing it once you click in the microphone.
