I am starting a service from MainActivity, which run indefinitely looking for incoming and outgoing calls to record.
Why is that the sample "switch-case" doesn't work?
No error occurs but I can record only each of incoming and outgoing.
The service is killed after recording the call, it will be recreated START_STICKY
but never going to get started.
Please help. Thanks in advance!
Is there any other codes to record incoming and outgoing call in android?

final MediaRecorder recorder = new MediaRecorder();
String inc_num="", fname;
public void onCallStateChanged(int state, String incomingNumber) throws IllegalStateException
{
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:

Toast.makeText(getApplicationContext(), "CALL_STATE_IDLE : "+Boolean.toString(recording), Toast.LENGTH_SHORT).show();
if(recording==true)
{
recorder.stop();
recorder.reset();
recorder.release();
Toast.makeText(getApplicationContext(), "Released_idle", Toast.LENGTH_SHORT).show();

break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Toast.makeText(getApplicationContext(), Boolean.toString(recording)+" : Offhook",Toast.LENGTH_SHORT).show();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
String file= Environment.getExternalStorageDirectory().toString();
String filepath= file+"/111111111111Aandroid_Subui";
File dir= new File(filepath);
dir.mkdirs();
if(inc_num.length()==0)
{

}
filepath+="/"+fname+".3gp";
recorder.setOutputFile(filepath);
try {
recorder.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
recorder.start();
recording=true;
break;
case TelephonyManager.CALL_STATE_RINGING:
//CALL_STATE_RINGING
inc_num = incomingNumber;
Toast.makeText(getApplicationContext(), "CALL_STATE_RINGING : "+incomingNumber, Toast.LENGTH_SHORT).show();
break;
default:
Toast.makeText(getApplicationContext(), "Default reached", Toast.LENGTH_SHORT).show();
break;
}
}
}
}
Finally Got the Result... Now I can record both incoming and outgoing calls(2.2)..
Changed the whole structure..
Here is my CallRecordingService.java Toasting will make you understood whats going arround... :)

Instead of myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
use myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
This particular option is described here> http://developer.android.com/reference/android/media/MediaRecorder.AudioSource.html Voice call uplink + downlink audio source That means the recording will contain both voices.
Be careful when you start recording. When the call is initiated or when the other-party answer the call.
