String url ="http://67.23.166.35:80/android/insertv2.php";

HttpPost request = new HttpPost(url);

Can you paste the exception you are getting from ddms-log when force close happens. That way we can get the exact idea why this is happening. From what i am guessing you are probably doing network operation in Main Thread(UI) which is not allowed after Android 3.0. Please check out this post for details. I might be wrong about that since i am assuming.

AsyncTask:

Thread :

new Thread(){
  public void run(){
    HttpEntity entity;
    HttpClient client = new DefaultHttpClient();
    String url ="http://67.23.166.35:80/android/insertv2.php";

    HttpPost request = new HttpPost(url);
    StringEntity se = new StringEntity(datatoServer);
    se.setContentEncoding("UTF-8");
    se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json"));
    entity = se;
    request.setEntity(entity);
    HttpResponse response = client.execute(request);
    entity = response.getEntity();
        runOnUiThread(new Runnable() {

            public void run() {
                // TODO Auto-generated method stub
                // do what you have to do
            }
    });
  }
}.start();

Donot do network operations in main thread.Use AyncTask

Example:

 AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>() {

    @Override
    protected void onPreExecute() {
         //Show UI

    }

    @Override
    protected Void doInBackground(Void... arg0) {
         // do your background process 
        HttpEntity entity;
        HttpClient client = new DefaultHttpClient();
        String url ="http://67.23.166.35:80/android/insertv2.php";

        HttpPost request = new HttpPost(url);
        StringEntity se = new StringEntity(datatoServer);
        se.setContentEncoding("UTF-8");
        se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json"));
        entity = se;
        request.setEntity(entity);
        HttpResponse response = client.execute(request);
        entity = response.getEntity();
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
                      //Show UI (Toast msg here)

    }

    };

    task.execute((Void[])null);

else you can add 

 super.onCreate(savedInstanceState);

         StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                .permitAll().build();
        StrictMode.setThreadPolicy(policy);

Check following links buddy,

I am assuming that you are getting NetworkOnMainThreadException so you should use AsyncTask and RunOnUiThread methods for sending data to server

for Implement AsyncTask

Hope it will help you.
