copied!<p>Like Sergey, I've found that the included json library <code>org.json.*</code> on Android is far simpler to use than <code>GSON</code>.</p> <p>For example, in your scenario - your JSON parsing code would look like this.</p> <pre><code>String jsonData = readUrl("http://api.geonames.org/weatherIcaoJSON?ICAO=LSZH&username=demo"); JSONObject weatherJSONObject = new JSONObject( jsonData ); try { // Not sure the format of your data, but you would want something like this String clouds = weatherJSONObject.getString("clouds"); } catch (JSONException e) { e.printStackTrace(); } </code></pre> <p>You would also benefit from <code>AsyncTask</code> or <code>Thread</code>. You never want to run long running operations on the UI thread because the UI will appear unresponsive and sluggish.</p> <p>Below is an example on how you can use <code>AsyncTask</code> to achieve your goal. Read more about it <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="nofollow">here</a></p> <pre><code>private class FetchJSONDataTask extends AsyncTask<String, Void, JSONObject> { // This gets executed on a background thread protected JSONObject doInBackground(String... params) { String urlString = params[0]; String jsonData = readUrl( urlString ); JSONObject weatherJSONObject = new JSONObject( jsonData ); return weatherJSONObject; } // This gets executed on the UI thread protected void onPostExecute(JSONObject json) { //Your function that takes a json object and populates views setUpViews( json ); } } </code></pre> <p>And to execute your task, you should run this code in your activity. </p> <pre><code>FetchJSONDataTask task = new FetchJSONDataTask(); task.execute( new String[] { "http://api.geonames.org/weatherIcaoJSON?ICAO=LSZH&username=demo" } ); </code></pre> <p>Note: This code is untested, but that should be the general idea.</p>
