     @Override
        protected String doInBackground(String... params)   
        {           
            BufferedReader inBuffer = null;
            String url = "http://ec2-54-243-205-92.compute-1.amazonaws.com/Tests/ping.php";
            String result = "fail";
            try {
                HttpClient httpClient = new DefaultHttpClient();
                HttpPost request = new HttpPost(url);
                List<NameValuePair> postParameters = new ArrayList<NameValuePair>();
                postParameters.add(new BasicNameValuePair("Password", "EGOT"));

                UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(
                        postParameters);

                request.setEntity(formEntity);
                HttpResponse response = httpClient.execute(request);//btw, i'm NOT very sure if this will work LOL
                       result = response.toString();

            } catch(Exception e) {
                // Do something about exceptions
                result = e.getMessage();
            } finally {
                if (inBuffer != null) {
                    try {
                        inBuffer.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            }
            return  result;
        }

        protected void onPostExecute(String result)
        {       
            //textView.setText(page); 
            Toast toast = Toast.makeText(getApplicationContext(), result, Toast.LENGTH_LONG);
          toast.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.ping_server, menu);
    return true;
}

}

Answer 1

You cannot simply convert a HTTPResponse to a String, you'll need to read it into an input stream or similar, give

Replace:

result = response.toString();

with

result = EntityUtils.toString(response);

a go.

Answer 2

The response not only a String type in some times, it can also be a binary, I suggest you should retrieve the content from inputstream

HttpEntitiy entitiy = response.getEntity();
Inputstream inputstream = entitiy.getContent();
//do what you want, e.g. convert to string or decode as bitmap
