How can I record voice and record Call in Android? [closed]

Answer 1

As far as I know, all the applications that record voice calls on Android have the same problem: they only work on some phones, while on other phones you can only hear one side of the conversation. Some of these apps try to solve this problem by recording from the microphone as well.

If you have root permissions on your Android phone, then I believe there are apps that work better because they have access to the lower level streams, as Emmanuel specified in his answer.

Answer 2

You can't record a phone conversation on Android. The streams are in the lower level operating system and are not accessible in the application level. Sorry.

Answer 3

The API is apparently there, but makers have disabled their radio firmware from being able to do this.

Answer 4

Depends on phone to phone e.g. You cannot record a call on nexus and motorola phones as they do not allow recording from mic till the call is on going. But the same recording from mic while on call works on most samsung and galaxy devices.

Answer 5

Yes It is possible just do this

final MediaRecorder callrecorder = new MediaRecorder();
callrecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
callrecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
callrecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

callrecorder.setOutputFile(filepath);

try {
    callrecorder.prepare();
} catch (IllegalStateException e) {
    System.out.println("An IllegalStateException has occured in prepare!");
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {

    //throwing I/O Exception
    System.out.println("An IOException has occured in prepare!");
    // TODO Auto-generated catch block
    e.printStackTrace();
}

try {
    callrecorder.start();
} catch(IllegalStateException e) {
    e.printStackTrace();
    //Here it is thorowing illegal State exception
    System.out.println("An IllegalStateException has occured in start!");
}

for stopping you can use

callrecoder.stop();

Answer 6

I dont know if its possible but as far as API goes

recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);

this line compiles well in my code where recorder is an Object of MediaRecorder and I was once working on such project but later the project was dumped so not sure if it works or not
