list.add( jsonArray.getString(i) );
Log.i("Output",jsonArray.getString(i));
}
return "Nothing";
} catch (JSONException e) {
e.printStackTrace();
return json_string;
}
}
private String execHttpRequest(String url) {
try {
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(url);
//We want the JSON version of resource
httpget.addHeader("accept", "application/json");
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
return EntityUtils.toString(entity);
} catch (Exception e) {
e.printStackTrace();
return e.getMessage();

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn = (Button) findViewById(R.id.btn_click_me);
txt = (TextView) findViewById(R.id.txt);
btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
String s = execHttpRequest(SERVICE_URL);
txt.setText(getTheTimeFromJSONString(s));
}
});
