Android HTTP Get

by

Android is probably executing your request just fine. You just seem to be ignoring the data returned by the server. You could do something like this, for instance:

public void changText(View view) {
    TextView textv = (TextView)findViewById(R.id.textview1);
    textv.setText("Text Has Been Changed");
    BufferedReader in = null;
    String data = null;

    try{
           HttpClient httpclient = new DefaultHttpClient();

           HttpGet request = new HttpGet();
           URI website = new URI("http://alanhardin.comyr.com/matt24/matt28.php");
           request.setURI(website);
           HttpResponse response = httpclient.execute(request);
           in = new BufferedReader(new InputStreamReader(
                   response.getEntity().getContent()));

           // NEW CODE
           String line = in.readLine();
           textv.append(" First line: " + line);
           // END OF NEW CODE

           textv.append(" Connected ");
       }catch(Exception e){
           Log.e("log_tag", "Error in http connection "+e.toString());
       }
}

It looks like your server is returning a JSON object, so you would probably want to do something more intelligent such as read the entire response, parse it (using new JSONArray(response)), and extract relevant fields, but the above code would at least verify that Android is executing your query.

EDIT: From the exception you report, it appears that you are running your code on the main UI thread. As of API 11 that is prohibited (and was frowned upon before that). There are several articles on how to fix this. See the Guide topic Painless threading as well as tutorials here and here. Also see this thread for more information.
