The suggested way to download the json is not recommended for android anymore as the http client has been removed from the sdk as of api 23.<br> However, <strong>the parsing logic below still applies</strong></p> </blockquote> <hr> <p>Android has all the tools you need to parse json built-in. Example follows, no need for GSON or anything like that.</p> <p><strong>Get your JSON:</strong></p> <pre><code>DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams()); HttpPost httppost = new HttpPost(http://someJSONUrl/jsonWebService); // Depends on your web service httppost.setHeader("Content-type", "application/json"); InputStream inputStream = null; String result = null; try { HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); inputStream = entity.getContent(); // json is UTF-8 by default BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } result = sb.toString(); } catch (Exception e) { // Oops } finally { try{if(inputStream != null)inputStream.close();}catch(Exception squish){} } </code></pre> <p>now you have your JSON, so what?</p> <p><strong>Create a <a href="https://developer.android.com/reference/org/json/JSONObject.html" rel="noreferrer">JSONObject</a>:</strong></p> <pre><code>JSONObject jObject = new JSONObject(result); </code></pre> <p><strong>To get a specific string</strong></p> <pre><code>String aJsonString = jObject.getString("STRINGNAME"); </code></pre> <p><strong>To get a specific boolean</strong></p> <pre><code>boolean aJsonBoolean = jObject.getBoolean("BOOLEANNAME"); </code></pre> <p><strong>To get a specific integer</strong></p> <pre><code>int aJsonInteger = jObject.getInt("INTEGERNAME"); </code></pre> <p><strong>To get a specific long</strong></p> <pre><code>long aJsonLong = jObject.getLong("LONGNAME"); </code></pre> <p><strong>To get a specific double</strong></p> <pre><code>double aJsonDouble = jObject.getDouble("DOUBLENAME"); </code></pre> <p><strong>To get a specific <a href="http://developer.android.com/reference/org/json/JSONArray.html" rel="noreferrer">JSONArray</a>:</strong></p> <pre><code>JSONArray jArray = jObject.getJSONArray("ARRAYNAME"); </code></pre> <p><strong>To get the items from the array</strong></p> <pre><code>for (int i=0; i < jArray.length(); i++) { try { JSONObject oneObject = jArray.getJSONObject(i); // Pulling items from the array String oneObjectsItem = oneObject.getString("STRINGNAMEinTHEarray"); String oneObjectsItem2 = oneObject.getString("anotherSTRINGNAMEINtheARRAY"); } catch (JSONException e) { // Oops } } </code></pre>
