android app crashing after adding navigation drawer

i am working on this android app.In this app, the "StartingActivity.java" is automatically getting changed to "HomeActivity.java" which contains the Navigation Drawer. But while changing the activity,the app crashes.Please help.. Here is the code

StartingActivity.java

 package com.example.abhi.mymanager;
 import android.content.Intent;
 import android.os.Handler;
 import android.support.v7.app.ActionBarActivity;
 import android.os.Bundle;
 import android.view.Menu;
 import android.view.MenuItem;

 public class StartingActivity extends ActionBarActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_starting);
  // for sending it to another activity after a time
    Handler handler=new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
          Intent i=new Intent(StartingActivity.this,HomeActivity.class);
          startActivity(i);
          }
        }
    },5000);
  }

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

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
  }
}
