    <p>I have an interesting question for you. I have a function in Android that interacts with the ui by loading a listview with data from a remote server. As expected, this makes my app extremely sluggish.</p> <p>With the minimum amount of code, how do I put this function on its own thread or A Sync Task, while still allowing it to perform like a normal function</p> <p>It did not be extremely efficient. I just need to do this with the minimum amount of code possible.</p> <pre><code>try { //getjson file HttpClient client = new DefaultHttpClient(); HttpGet get = new HttpGet(url); HttpResponse responseGet = client.execute(get); HttpEntity resEntityGet = responseGet.getEntity(); if (resEntityGet != null) { InputStream instream = resEntityGet.getContent(); BufferedReader str = new BufferedReader(new InputStreamReader( instream)); String ans = new String(""); build = new String(""); while ((ans = str.readLine()) != null) { build = build + ans; } //parse json file JSONObject total = new JSONObject(build); JSONArray prices = null; if (!total.isNull("title")){ Prices = title.getJSONArray("title"));} ArrayList&lt;data&gt; newArray = new ArrayList&lt;data&gt;(); for(int i=0;i&lt;Prices.length();i++) { JSONObject price = null; price = Prices.getJSONObject(i); data name = new data (price.getString("StoreName"),price.getString("price"),price.getString("Link")); newArray.add(name); } stockArr = new data[newArray.size()]; stockArr = newArray.toArray(stockArr); //add to listview ListView listView = (ListView) findViewById(R.id.mylist); listadapter adapter = new listadapter(this,R.layout.listview_item_row, stockArr); listView.setAdapter(adapter); } } catch(Exception e) { Toast.makeText(getApplicationContext(),e.toString(), 10).show(); } </code></pre>

    2. COpost your code. Ideally, you should hit the remote server, fetch the data, parse it in background and update the adapter in onPostExecute. Additionally, you can use onProgressUpdate if you want intermediate updates, helpful when parsing huge responses

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
