Android : Error when running this android app

Whenever I try running this app in the emulator I get this error:

here is my main activity

package com.spookyapps.lollatone;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;


public class MainActivity extends Activity {

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

        final Sounds mSound = new Sounds();
        Thread thread = new Thread(new Runnable() {
            public void run() {
                mSound.record();
            }
        });
        thread.start();


        try {
            wait(10000);
        } catch (InterruptedException e) {
            Log.e("Record", "wait failed");
        }

        //Sounds.mIsRecording = false;

        try {
            thread.join();
        } catch (InterruptedException e) {
            Log.e("Thread", "Join failed");
        }

        mSound.play();
        finish();
        /*GridView gridView = (GridView)findViewById(R.id.gridview);
        gridView.setAdapter(new ImageAdapter(this));

        gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View v, int position, long id) {
                Toast.makeText(MainActivity.this, "" + position, Toast.LENGTH_LONG).show();
            }
        }); */
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

It's supposed to automatically try recording audio and then then playing it back once the app starts but the app never starts at all and I just get those messages in the logcat
