        } else {

            Log.d(Log_Tag, "onDestroy()");

            recorder = null;
        }
        return super.onStartCommand(intent, flags, startId);
    }
}

 

package com.example.psa987.recorderservice;
//MainActivity.java
import android.content.Intent;
import android.media.MediaRecorder;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class MainActivity extends ActionBarActivity implements View.OnClickListener {
private  static final String Log_Tag = "RecorderService";
    Button record;
    private MediaRecorder recorder = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        record = (Button) findViewById(R.id.record);// 녹음
        record.setOnClickListener(this);
    }
    public  void onClick(View v) {
        if(recorder == null){
            Log.d(Log_Tag, "onClick() record ");
            startService(new Intent(this, RecordService.class));
        record.setText("녹음 중지");
    } else {
            Log.d(Log_Tag, "onClick() record ");
            stopService(new Intent(this, RecordService.class));
            recorder = null;
            record.setText("녹음 시작");

        }
    }
}

녹음 버튼을 누르면 녹음이 시작되었다고 나오는데 파일은 없네요

onCreate에 여러가지 써 봤다가 아닌것 같아서 비워놨는데

어떤 식으로 해야 할지 알려주세요
