                }

            recorder = new MediaRecorder();
            recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
            recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);

//获取存储路径

ok i have myself solved my problem after a little R&D and posting the solution here so that it could help somebody like me....

//getting path for storage

File audioFile = context.getCacheDir();
        OUTPUT_FILE =audioFile.getPath()+"/"+"myAudioFile.3gp";

//Function for Recoding Voice
	private void startRecording() throws IllegalStateException, IOException{ 
		
		recorder = new MediaRecorder();
		recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
		recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
		recorder.setOutputFile(OUTPUT_FILE);
		recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

        try {
        	recorder.prepare();
        } catch (IOException e) {
            Log.e("development", "prepare() failed");
        }

        recorder.start();
	}
